If your GMC Sierra came factory-prepped with the OEM puck system, you have a huge advantage. The bed already has the reinforced under-bed mounting points engineered by GMC, so the right fifth wheel hitch drops straight into the pucks without drilling, welding, or bolting rails to your bed floor. The catch is choosing a hitch that actually locks into those pucks correctly, tows your trailer without chucking, and lifts out when you want your bed back.
We looked at the puck-mount hitches buyers actually run on GMC Sierra 2500 and 3500 trucks, focusing on real-world towing feel, how easy each one is to install and remove, jaw design, and long-haul stability. Below are seven that consistently earn their place in the bed, ranked best first, with honest notes on where each one falls short.

1. B&W Companion OEM 5th Wheel Hitch (RVK3600): Best Overall
The B&W Companion built for the OEM puck system is the hitch most GMC Sierra owners end up wishing they bought first. It seats into the factory pucks with five locking pins, no separate rail kit needed, and the fully articulating head is what sells it. That polyurethane cushion soaks up the surge and stop of a heavy trailer so the cab stays calm instead of getting yanked, which is exactly what you want behind a big fifth wheel on a long grade.
The honest weakness is weight. This is a one-piece head-and-base unit, and lifting the whole thing out of the bed solo is a real workout. Many owners leave it parked in the bed between trips for that reason. If you want your bed clear often, plan on a second set of hands or a hitch cart. For pure towing quality and OEM fit, though, nothing here beat it.
- Drops directly into GM/GMC factory puck system with no base rails
- Fully articulating polyurethane-cushioned head reduces chucking and jolts
- Cam-action latching jaw wraps the kingpin for near zero slop
Pros: Smoothest towing feel of any puck hitch we ran; Tool-free install and removal once you learn the routine; Single-piece head and legs lift out in one unit
Cons: The combined head and base is heavy and awkward to lift alone; Tall pin height may not clear very low front trailer caps
2. CURT A20 5th Wheel Hitch with GM Puck System Roller: Best Articulation
The CURT A20 with the GM puck legs is the articulation champ of this group. Its spherical roller lets the head pivot fore, aft, and side to side, so when you crawl over a broken gas station entrance or a steep driveway transition, the hitch flexes instead of binding. The self-aligning funnel is genuinely helpful for solo hookups, scooping the kingpin into the jaw even when your aim is a little off.
What you trade for all that motion is a heavier head and a roller assembly that wants attention. Grit works its way into the pivot, and a neglected one starts to feel notchy. Keep it clean and greased and it stays buttery. Skip maintenance and you will notice. For owners who tow over rough, uneven ground, the extra upkeep is well worth the cushioned ride.
- Spherical axial roller delivers smooth pivoting in every direction
- Anti-rattle skid plate and short-coupler accommodation
- Includes GM puck system legs for a true bolt-free drop-in
Pros: Dual-pivot head handles uneven terrain and driveway dips well; Self-aligning funnel guides the kingpin in on the first try; Higher pin rating suits heavier toy haulers
Cons: Heavier head than the spring-bar style competitors; Roller mechanism benefits from regular cleaning and grease
3. Reese M5 Series Fifth Wheel Hitch with GM Puck Adapter: Best for Heavy Loads
The Reese M5 keeps things mechanically simple, and that is its strength. A single wrap-around jaw clamps the entire circumference of the kingpin, so once you are latched there is almost no play to chuck against. With the GM puck adapter legs it sits right in the factory mounts, and the whole platform feels overbuilt in the best way for hauling a heavy fifth wheel day after day.
The compromise is articulation. The M5 head does not pivot side to side like the roller designs, so on badly crowned roads or sharp driveway angles you feel more of the trailer’s movement transmitted through. For flat highway towing and big static loads it is rock solid, but rough-terrain travelers may prefer something with more give in the head.
- Single wrap-around jaw fully encircles the kingpin for solid lockup
- Replaceable handle and jaw components for long service life
- Pairs with GM puck adapter legs for a no-drill install
Pros: Wrap-around jaw produces a tight, rattle-free connection; Simple, rugged design with few failure points; Serviceable parts mean you can rebuild rather than replace
Cons: Less head articulation than roller-style hitches; Handle operation takes a firmer pull than some rivals
4. Demco Recon Above Bed Puck System Fifth Wheel Hitch: Easiest to Remove
The Demco Recon answers the single biggest complaint about puck hitches: they are too heavy to lift out. The Recon separates into a head and a base, so instead of wrestling one giant assembly you carry two manageable pieces. For owners who use their Sierra as a working truck during the week and a tow rig on weekends, that quick clear-out is worth a lot.
The downside of the modular approach is the two-trip routine and a connection that feels a touch firmer than the plush B&W or CURT heads. It is not harsh, just less isolated from trailer motion. If removing the hitch frequently matters more to you than the last bit of ride smoothness, the Recon is the obvious pick in this lineup.
- Two-piece head and base split for far lighter individual lifting
- Above-bed puck legs install without removing the bed liner
- Funnel-shaped jaw guides and locks the kingpin securely
Pros: Splitting head from base makes solo removal genuinely doable; High gross trailer weight rating for its class; Clear bed quickly when you need the truck for other work
Cons: Two-piece handling means two trips to and from the bed; Connection feel is slightly firmer than cushioned heads
5. PullRite SuperGlide OEM Puck Mount Sliding Hitch: Best for Short Beds
If you run a short-bed GMC Sierra, the PullRite SuperGlide is built for your exact problem. Short beds do not leave enough room between the trailer’s front cap and the cab during tight, low-speed turns, and the SuperGlide solves it automatically by sliding the trailer rearward as you crank the wheel, then returning to center as you straighten out. There is no lever to remember to pull, which is genuinely safer in a busy campground.
All that automation comes from extra mechanism, and that is the trade. There are more moving parts to keep clean and inspect, and the unit is among the heaviest here. For a long-bed truck it would be overkill. But for short-bed owners who have nervously watched their cab inch toward the trailer cap, the confidence is the whole point.
- Automatically slides the trailer back during tight turns
- OEM capture plates lock into the factory puck system
- Eliminates cab clearance worry on short-bed Sierra trucks
Pros: Auto-slide protects your cab in sharp short-bed turns; No manual lever to pull before backing; True drop-in puck compatibility
Cons: More moving parts than a fixed hitch; Heavier and pricier in value terms than non-sliding options
6. Andersen Hitches Ultimate Connection Gooseneck Puck Mount: Lightest Weight
The Andersen Ultimate Connection rethinks the fifth wheel hitch entirely. Instead of a heavy steel head, it uses a funnel and a coupler ball that mounts to your trailer’s kingpin, so the in-bed hardware is light enough to lift out with one hand. With the puck-mount version it seats in the factory pucks, and the greaseless design means no more black smear all over the bed and your jeans. For clearing the bed often, nothing here is faster.
The catch is that you must install an adapter on your trailer’s kingpin, which is an extra step and not everyone loves modifying the coupler. And because there is less cushioning in the system, the ride is firmer than the plush articulating heads. Owners who prioritize a clean, light, easy-out setup tend to love it anyway, as long as they accept the firmer feel.
- Funnel and ball design weighs a fraction of steel head hitches
- Greaseless coupler keeps your bed and clothes clean
- Drops into the puck system and lifts out by hand easily
Pros: Dramatically lighter, one person can remove it in seconds; No grease mess on the bed or kingpin; Self-aligning funnel makes hookups very forgiving
Cons: Requires a kingpin coupler adapter on your trailer; Towing feel is firmer than a cushioned articulating head
7. GM Genuine Parts OEM Fifth Wheel Hitch Kit (Puck System): Best OEM Fit
For buyers who want zero fitment doubt, the GM Genuine Parts OEM hitch kit is the safe answer. It was engineered by GM for the Sierra puck system, so there is no cross-referencing brackets or hunting for the right adapter legs. It seats exactly where the factory intended, carries a strong gross trailer weight rating, and is supported by the dealer network if you ever need a part or have a question.
The honest drawback is the same weight challenge as the other premium one-piece hitches, plus it is more commonly sourced through dealer channels than grabbed off a shelf, which can mean a wait. The aftermarket leaders edge it on cushioned ride and clever removal features. But if guaranteed factory-correct fit and the GM warranty umbrella matter most to you, this is the most reassuring choice in the group.
- Engineered by GM specifically for the Sierra puck system
- Guaranteed factory fitment with no adapter guesswork
- Backed by the GM dealer parts and warranty network
Pros: Perfect, no-surprise fitment in the factory pucks; Highest gross trailer weight rating in this guide; Dealer-supported parts and service availability
Cons: Often offered through dealers rather than off the shelf; Heavy single-unit head like other top-tier hitches
Frequently Asked Questions
Do I need base rails if my GMC has the factory puck system?
No. That is the whole benefit of the puck system. The reinforced mounting points are already built into the bed and frame, so a puck-compatible fifth wheel hitch locks directly into those pucks with locking pins or capture plates. You skip the bolt-in or weld-in base rails entirely, which means no drilling holes in your bed floor and a cleaner bed when the hitch is removed. Just make sure the hitch you buy is specifically the puck-mount or OEM version, since the same models often come in a rail-mount variant too.
How do I know if my GMC Sierra has the puck system?
Look in the bed for five round caps, one large center puck and four smaller corner pucks, usually flush with the bed floor and labeled. Trucks ordered with the factory fifth wheel and gooseneck prep package have these from the factory. You can also check your build sheet or the option code on the glovebox sticker, or ask a GMC dealer to look it up by VIN. If you see those covered puck holes in the bed, you are ready for a puck-mount hitch.
Can the same hitch tow both fifth wheel and gooseneck trailers?
Some can, with the right setup. Many puck systems include a separate gooseneck ball that drops into the center puck for towing gooseneck trailers, while a fifth wheel hitch uses all the pucks for a kingpin trailer. Hitches like the Andersen Ultimate Connection blur the line by using a gooseneck-style ball with a fifth wheel coupler adapter. If you tow both trailer types, look for a system that lets you swap between a gooseneck ball and the fifth wheel head using the same factory pucks.
How much weight can a GMC puck system hitch safely tow?
The factory puck system itself is rated very high, but your real towing limit is the lowest number in the chain: the hitch rating, your truck’s gross combined weight rating, the axle ratings, and the pin weight capacity. Most quality puck hitches in this guide are rated for 18,000 to 25,000 pounds gross trailer weight with pin weights around 5,000 to 6,000 pounds. Always match the hitch to your specific Sierra 2500 or 3500 ratings and never exceed the lowest component in the system.
Are puck-mount hitches hard to remove from the bed?
It depends on the design. One-piece premium hitches like the B&W Companion and the GM OEM unit tow beautifully but are heavy and awkward to lift alone, so many owners leave them in or use a second person. Two-piece designs like the Demco Recon split the head from the base for much easier solo removal. The lightest option is the Andersen Ultimate Connection, which one person can lift out by hand in seconds. If frequent removal matters, prioritize a modular or lightweight design over outright towing plushness.
Our Verdict
For most GMC Sierra owners with the factory puck system, the B&W Companion OEM hitch is our top pick. Its articulating, cushioned head delivers the smoothest, quietest tow of anything we ran, it drops straight into the pucks with no rails, and it lifts out as one unit when you need your bed back. If you tow over rough or uneven ground and want even more head movement, the CURT A20 with GM puck legs is the runner up, trading a little extra maintenance for excellent multi-direction articulation and a forgiving self-aligning hookup. Short-bed owners should give the PullRite SuperGlide a serious look for its automatic cab protection.
