If your Ford F250 Super Duty has started sagging at the doors, squeaking over bumps, or showing rust where the cab meets the frame, your body mounts are the likely culprit. These rubber and polyurethane bushings sit between the cab and the frame rails, and on high mileage Super Duty trucks they crush, crack, and rot out, which throws off door gaps and lets road vibration straight into the cabin. Replacing them restores ride height, tightens up the body, and quiets the cab.
We looked at the body mount kits that actually fit the F250, from direct OEM style rubber replacements to firmer polyurethane upgrades built for towing and off road use. Below are seven kits worth your time, ranked by fitment, durability, hardware quality, and how well they hold up under load. Whether you want a quiet factory feel or a stiffer setup that resists cab roll, there is an option here for your truck and your budget.

1. Energy Suspension Body Mount Bushing Set 4.4118G: Best Overall
Energy Suspension is the name most Super Duty owners land on once they have replaced a set of mushy factory mounts, and the 4.4118G kit is the reason why. This is a full polyurethane set covering both the cab and the radiator core support positions, so you address the whole truck in one job rather than chasing one bad puck at a time. The Hyper-Flex compound shrugs off the oil, road salt, and constant compression that destroy OEM rubber, which is exactly why these are the go to for trucks that tow or plow.
The honest trade off is feel. Polyurethane is firmer than rubber by design, so you will notice a touch more shake at idle and a little more road texture through the floor compared to a soft factory mount. The graphite-loaded formula keeps squeaks down, but it is not silent forever, so a dab of the supplied lubricant on reassembly matters. If you want OEM quiet, look lower on this list. If you want mounts that outlast the truck, this is the set.
- Hyper-Flex polyurethane resists crush, oil, and road salt better than factory rubber
- Complete set covers cab and radiator core support positions in one box
- Available in black or red durometer-matched compound for a firmer but livable ride
Pros: Holds ride height under towing and heavy bed loads; Will not rot or collapse the way OEM rubber does; Includes graphite-impregnated formula to limit squeak
Cons: Transmits slightly more vibration than soft rubber mounts; You supply or reuse the long center bolts and washers
2. Dorman 924-227 Body Mount Bushing Kit: Best OEM Replacement
For owners who just want their F250 back to the way Ford built it, the Dorman 924-227 is the cleanest path. It uses a rubber and steel construction tuned to match the original durometer, so once installed your door gaps line up, the cab sits at proper height, and the ride stays as quiet and compliant as it was new. The big practical win is that Dorman includes new mounting bolts, which is a lifesaver on a Super Duty where the original hardware is often rusted into one solid lump.
The weakness is the same one every rubber mount carries. This is a restoration part, not an upgrade part, so it will soften and break down over years of heat cycling and salt exposure the same way the originals did, just on a fresh clock. It also will not resist cab roll under serious towing the way a poly mount does. For a daily driven or lightly worked Super Duty that you want to feel stock again, though, this kit is hard to beat.
- Replicates the original rubber durometer for a stock ride and door gap
- Kit includes new mounting bolts so you are not reusing rusted hardware
- Engineered to restore factory cab height and quiet operation
Pros: True factory feel with no added vibration; Bundled fresh bolts make a stuck-fastener job far easier; Wide availability and trusted Dorman support
Cons: Rubber will eventually degrade like any OEM style mount; Not as crush resistant under heavy towing as polyurethane
3. Prothane 6-110 Body and Cab Mount Kit: Best for Towing
If your Super Duty earns its keep behind a trailer, the Prothane 6-110 is built for you. This polyurethane cab mount kit is tuned firmer than a restoration part on purpose, which keeps the cab planted when a heavy load shifts weight around. That control translates into more consistent steering feel and less of the wallowy, disconnected sensation that worn mounts produce when you are hitched up. Prothane includes the sleeves and hardware so the job goes together without a mid-install supply run.
The cost of that control is comfort. On broken pavement and expansion joints you will feel more of the road than you would with the factory rubber or the Dorman kit, and that is the deliberate nature of the compound, not a defect. As with any poly mount, thorough greasing on reassembly is the difference between silent and squeaky a year later. For a work truck, the firmness is a feature. For a pavement-only family hauler, it may be more than you want.
- Firm polyurethane controls cab movement under heavy trailer loads
- Comes with the sleeves and hardware needed to complete the swap
- Resists deflection so steering and bed alignment stay consistent
Pros: Excellent cab control for trucks that tow or haul often; Hardware included reduces parts-store trips mid-install; Lifetime-style durability versus collapsing rubber
Cons: Noticeably stiffer ride on rough pavement; Some squeak possible if not greased thoroughly on assembly
4. Daystar KF04017BK Polyurethane Body Mount Bushings: Best Value Polyurethane
Daystar built its reputation on polyurethane suspension parts that punch above their weight, and the KF04017BK body mount set carries that forward for the Super Duty. You get the long-term benefits of poly, namely resistance to crush, salt, and chemical attack, at a more accessible entry point than the premium full kits. The black compound is UV and chemical resistant and made in the USA, and it holds your cab at the right height instead of slowly sinking the way tired rubber does.
The catch to watch is hardware. Depending on your exact F250 year and configuration, this set may not include every center bolt and washer you need, so confirm your fitment and be ready to source fresh hardware if your originals are seized or stripped. You will also pick up a little more noise and vibration than a soft rubber mount, which is the universal trade for poly durability. For owners who want the poly upgrade without stretching the budget, this is a smart pick.
- Durable polyurethane upgrade at an accessible entry point
- Black UV and chemical resistant compound made in the USA
- Maintains ride height without the collapse of worn rubber
Pros: Strong durability for the value; USA-made polyurethane with chemical resistance; Good middle ground between stock softness and full race firmness
Cons: May not include all center bolts depending on your truck year; Slightly more NVH than OEM rubber
5. Dorman 924-262 Cab Mount Bushing: Best Single Position Fix
Not every Super Duty needs a full set. On a lot of trucks one or two specific mounts, usually the rotted rear cab corners, fail long before the rest, and the Dorman 924-262 lets you address exactly that position without buying a whole kit. It is a direct-fit rubber and steel piece matched to factory specs, so installing it brings that corner back to correct height and snaps the door gap back into line. For a targeted repair, it is efficient and low effort.
The honest caveat is consistency. If your other mounts are also tired, dropping one fresh mount next to several crushed ones can leave the cab sitting unevenly and just move the squeak somewhere else. And like all rubber, it is a restoration part with a finite life, not an upgrade. Inspect every position before you commit to a single mount fix. If only one corner is truly gone, this is the right tool. If the whole set is soft, buy the full kit.
- Targets a single failed mount position instead of a full set
- Direct-fit rubber and steel design matches factory specs
- Restores correct height and door alignment at the worst corner
Pros: Lets you fix only the mount that has failed; Factory-matched ride and fitment; Simple, lower-effort repair
Cons: Mixing one new mount with old ones can leave height uneven; Rubber durability limits long-term life
6. Prothane 6-111 Radiator Core Support Bushing Kit: Best Front-End Companion Kit
Body mount jobs on the F250 often stop at the cab and ignore the radiator core support, which is exactly where a lingering front-end rattle hides. The Prothane 6-111 targets those core support bushings with polyurethane that resists the rust and crush that let the front clip work loose over the years. Paired with a cab mount kit, it turns a partial repair into a genuinely complete body mount refresh, which is why we treat it as the front-end companion to the sets above.
Be clear about scope before you buy. This kit only covers the radiator core support, so it is an add-on rather than a standalone fix, and you will still need a cab mount set for the rest of the truck. Installation is also more involved because reaching these bushings usually means pulling part of the front clip apart. If you are already in there chasing a front rattle or doing a full mount overhaul, though, this is the piece most people forget and later wish they had done.
- Replaces the often-overlooked core support bushings up front
- Polyurethane resists the rust and crush that loosen the front clip
- Pairs with a cab mount kit for a complete body mount refresh
Pros: Fixes front-end rattle that cab mounts alone miss; Durable poly in a frequently neglected spot; Affordable add-on to a full mount job
Cons: Only covers the core support, not the cab mounts; Front clip removal makes install more involved
7. Dorman 523-227 Body Mount Hardware and Bushing Set: Best Complete Hardware Bundle
The single worst part of a Super Duty body mount job is rarely the bushing, it is the rusted, seized hardware fighting you the whole way. The Dorman 523-227 was assembled with that reality in mind, bundling the rubber bushings together with the bolts, brackets, and washers so you can replace the corroded original hardware instead of wrestling it back into service. The rubber compound is matched for a stock feel, so the truck rides and sounds factory once it is back together.
This is still a rubber kit, so the same durability ceiling applies. It is a restoration solution that will age the way OEM mounts do rather than an upgrade that outlasts the truck, and the extra brackets and fasteners make it a heavier purchase than a bushing-only set. For someone facing a corroded frame where reusing hardware is not realistic, the convenience and completeness of this bundle are exactly what make the job doable in a single weekend.
- Includes bushings plus the bolts, brackets, and washers in one box
- Designed for trucks where the original hardware is too rusted to reuse
- Restores factory cab height with a stock-feel rubber compound
Pros: All-in-one bundle removes the rusted-bolt headache; Factory ride feel from matched rubber; Convenient single purchase for a full job
Cons: Rubber life is shorter than polyurethane; Heavier kit price for the added hardware
Frequently Asked Questions
How do I know if my F250 body mounts are bad?
The classic signs are sagging door gaps where the doors no longer line up flush with the body, a creaking or popping noise over bumps and driveways, and visible rust or crumbling rubber where the cab meets the frame rails. You may also feel more vibration in the cab and notice the cab shifting or rocking slightly when you climb in. Get under the truck and look at each mount. If the rubber is cracked, oil-soaked, flattened, or rotted away, or if you can see a gap that should not be there, the mounts are due. On Super Duty trucks the rear cab corner mounts and the radiator core support bushings tend to fail first.
Should I choose polyurethane or rubber body mounts for my F250?
It comes down to how you use the truck. Rubber mounts like the Dorman kits restore the exact factory ride, stay quiet, and feel stock, which is ideal for a daily driver or a lightly worked truck. Polyurethane mounts like the Energy Suspension, Prothane, and Daystar sets are firmer and far more durable. They resist crushing, rust, and chemical attack, hold ride height under load, and control cab movement when you tow or haul. The trade-off is a bit more vibration and the chance of squeak if you do not grease them well on install. Tow heavy or work the truck hard, go poly. Want quiet and stock, go rubber.
Do I need to replace all the body mounts at once?
Not always, but it is usually the smarter move. If only one corner has clearly failed, a single-position part like the Dorman 924-262 can fix it. However, on a high mileage Super Duty the mounts age together, so installing one fresh mount next to several crushed ones can leave the cab sitting unevenly and simply relocate the squeak. Since you already have the truck on a lift or jack stands and the access is the hard part of the job, replacing the full set saves you from repeating the labor in a year. Inspect every position before deciding, and if more than one looks tired, do them all.
Can I install F250 body mounts myself?
Yes, it is a doable DIY job for someone comfortable under a truck, but it is not a quick one. You will need a way to safely support the cab and lift it slightly off the frame, penetrating oil for the rusted bolts, and ideally an impact tool. The biggest challenge on a Super Duty is the corroded hardware, which is exactly why kits that include new bolts, like several of the Dorman sets, are worth the extra outlay. Work one or two mounts at a time so the cab stays supported, never get under an unsupported cab, and grease polyurethane mounts thoroughly to prevent squeaks. Budget a full day if rust is involved.
Will new body mounts fix my sagging doors and uneven gaps?
In most cases, yes. Sagging doors and uneven body gaps on an F250 are very often caused by collapsed or rotted body mounts letting the cab drop at one or more corners. Replacing the failed mounts restores the cab to its proper height and brings the door gaps back into alignment. That said, if the gaps stay off after fresh mounts, check for related issues like a bent hinge, a corroded cab corner, or frame damage. Body mounts are the first and most likely fix for sag, but they are not the only possible cause, so verify the mounts are truly the problem before and after the repair.
Our Verdict
For most F250 Super Duty owners, the Energy Suspension 4.4118G is our top pick. It covers the cab and radiator core support in one complete polyurethane kit, holds ride height under towing and heavy loads, and simply outlasts the factory rubber it replaces, which makes it the set you install once and forget. If you would rather keep that quiet, stock factory feel, the Dorman 924-227 is our runner up, restoring original ride height and door gaps with matched rubber and including fresh bolts to beat the rusted hardware that makes this job a chore. Choose by how you drive: poly for work and towing, rubber for a daily that you want feeling factory again.
