1. CPP Tubular Upper and Lower Control Arm Set: Best Overall
We compared CPP’s tubular control arm set against several competitors and found it offers the best balance of performance, durability, and ease of installation. The arms are made from heavy-wall steel tubing with fully welded seams and a durable powder coat finish. Based on owner feedback, most users report a noticeable improvement in steering response and cornering stability after installation. The included ball joints are high-quality and the polyurethane bushings provide a firm feel.
However, polyurethane bushings can develop squeaks if not greased periodically, which may be a drawback for those seeking a completely maintenance-free setup. If you prefer a quieter ride and are willing to spend more, consider arms with Delrin or spherical bearings. This set is ideal for street performance and mild track use, but if your build is primarily a show car or you have a very tight budget, you might look elsewhere.
- Precision-engineered tubular design improves suspension geometry and reduces unsprung weight.
- Includes premium ball joints and polyurethane bushings for long service life.
- Direct bolt-in replacement, no modifications required for stock spindles.
Pros: Excellent fit and finish out of the box.; Significant improvement in handling over stock arms.
Cons: Polyurethane bushings may squeak over time without proper lubrication.
2. UMI Performance 2214 Tubular Control Arms: Runner Up
UMI’s 2214 control arms are a strong contender, featuring greasable polyurethane bushings that help mitigate the common squeak problem. In our research, we found that the CNC-machined cross shafts provide a precise fit and allow for easy alignment adjustments. The arms are fully welded and powder coated in a choice of colors. Owner feedback generally praises the handling improvement and the overall quality of the welds.
However, a few users with aftermarket spindles noted that the ball joint taper required a small amount of grinding for proper fit. This is not a universal issue, but it is something to be aware of if you are using non-stock spindles. If you are running a mostly stock suspension and want a reliable, good-performing arm with easier maintenance, these are a solid choice. For those who want absolute bolt-on simplicity with stock parts, CPP might be a better fit.
- Greasable polyurethane bushings reduce squeaking and extend bushing life.
- CNC-machined cross shafts for precise alignment and easy adjustment.
- Includes ball joints and all necessary hardware for bolt-on installation.
Pros: Greasable bushings are a nice upgrade over standard poly.; Good value for the quality.
Cons: Some owners report slight alignment issues with aftermarket spindles.
3. Speedway Motors Tubular Control Arms: Budget Pick
Speedway Motors offers a budget-friendly option that still provides the benefits of tubular control arms. We compared the specifications and found they use similar materials to more expensive sets, though the fit and finish are not as refined. Owner feedback indicates that most users are satisfied with the handling improvement, especially for the price. The arms are lightweight and come ready to bolt on.
However, some users have reported occasional weld spatter or minor imperfections in the powder coat. Also, the included ball joints are adequate but may wear faster than higher-end units. If you are on a tight budget or building a driver that doesn’t see extreme use, these are a great value. But if you demand show-quality finish or plan to race, you may want to invest in a more premium set.
- Affordable price point without sacrificing essential quality.
- Lightweight tubular design reduces unsprung weight.
- Comes with ball joints and polyurethane bushings pre-installed.
Pros: Very competitive price for a complete set.; Good basic performance upgrade.
Cons: Weld quality can be inconsistent; inspect before installation.; Ball joints may have a shorter lifespan than premium brands.
4. Ridetech 11210199 StrongArms Control Arms: Premium Choice
Ridetech’s StrongArms are the premium option we evaluated. They are forged from steel and TIG welded for superior strength. The use of Delrin bushings eliminates deflection and provides precise suspension control, which is ideal for performance driving. Based on owner feedback, these arms transform the handling of tri fives, especially when paired with a good coilover system. The ball joints are high-quality and designed for longevity.
On the downside, Delrin bushings are stiffer and can transmit more road noise and vibration into the cabin compared to rubber or polyurethane. Also, the price is significantly higher than most competitors. If you are building a serious performance car or a track-focused machine and the budget allows, these are the best you can buy. For a street cruiser who values comfort, a poly-bushed arm might be a better choice.
- Forged steel construction for maximum strength and durability.
- Delrin bushings provide precise geometry with no deflection.
- Includes high-performance ball joints and all hardware.
Pros: Exceptional build quality and materials.; Delrin bushings offer great feedback and longevity.
Cons: Higher price may not suit all budgets.; Delrin can transmit more road noise than rubber or poly.
5. PST 6010 Polygraphite Control Arm Set: Best for Street Cruising
PST’s Polygraphite control arms are designed for those who want a stock appearance with modern bushing technology. We researched the Polygraphite material, which is a blend of polyurethane and graphite to reduce friction and noise. These arms are made from stamped steel like the originals, making them a direct replacement for worn-out factory arms. Owner feedback often highlights the ease of installation and the smooth, quiet ride.
However, because they are not tubular, they do not offer the weight savings or improved geometry of aftermarket tubular arms. They are also not as strong for aggressive driving or racing. If you are restoring a tri five to near-stock condition or you prioritize a quiet, comfortable ride over ultimate handling, these are a great choice. But if you plan to autocross or drive hard, you will benefit from a tubular set.
- Polygraphite bushings combine low friction with reduced noise.
- Original-style steel arms maintain stock geometry.
- Pre-assembled with ball joints and bushings for easy installation.
Pros: Quieter than polyurethane bushings.; Good for stock restoration builds.
Cons: Not as strong as tubular arms for high-performance use.; Heavier than tubular designs.
6. SC&C Stage 2 Street Comp Control Arms: Performance Upgrade
SC&C’s Stage 2 arms are designed for enthusiasts who want to fine-tune their suspension. In our evaluation, the adjustable cross shafts stood out as a key feature, allowing up to 6 degrees of caster adjustment. This can dramatically improve highway stability and cornering. The arms are tubular steel with good weld quality and come with polyurethane bushings and ball joints. Owner feedback is very positive regarding the handling gains.
However, the adjustability adds complexity and cost. If you are not planning to have the car professionally aligned or do not need the extra caster, you may be paying for features you won’t use. Also, some users noted that the instructions could be more detailed. This set is ideal for the performance-minded builder who wants to maximize suspension potential. For a simple bolt-on upgrade, a non-adjustable set may be more straightforward.
- Adjustable cross shafts allow for caster and camber tuning.
- Increased caster range improves straight-line stability.
- Includes high-quality ball joints and polyurethane bushings.
Pros: Adjustability is great for dialing in alignment.; Significant handling improvement over stock.
Cons: More expensive than non-adjustable sets.; Installation may require more expertise to set up.
7. Proforged 100-10001 Upper and Lower Control Arms: OEM Replacement Plus
Proforged offers a straightforward OEM-style replacement control arm set. We noted that they are made from stamped steel and come with rubber bushings and ball joints pre-installed. This makes them a convenient option for those simply replacing worn-out parts without seeking performance gains. Owner feedback indicates they fit well and restore original handling characteristics.
However, rubber bushings have a shorter lifespan and can deflect more under load, leading to less precise handling. If you are looking for any upgrade in performance, these will not provide it. They are best suited for a budget restoration or for a daily driver where comfort and low cost are priorities. For anyone wanting improved handling, we recommend spending a bit more on tubular arms with polyurethane or Delrin bushings.
- Direct OEM replacement with rubber bushings for a quiet ride.
- Includes premium ball joints and all hardware.
- Powder coated for corrosion resistance.
Pros: Affordable and simple installation.; Maintains stock ride quality.
Cons: Rubber bushings wear faster than polyurethane.; No performance improvement over stock.
Frequently Asked Questions
What are tri five control arms?
Tri five control arms are suspension components designed for 1955, 1956, and 1957 Chevrolet passenger cars. They connect the frame to the steering knuckle and allow the wheels to move up and down. Upgraded tubular arms are popular for improving handling and reducing weight.
Do I need to replace both upper and lower control arms?
It is generally recommended to replace both upper and lower control arms as a set to ensure balanced geometry and performance. However, if only one side is worn, you can replace just that arm, but mixing old and new may lead to uneven handling.
What is the difference between tubular and stamped steel control arms?
Tubular control arms are made from round or square tubing and are lighter and stronger than stamped steel arms. They also allow for improved suspension geometry. Stamped steel arms are heavier and flex more but are cheaper and maintain a stock appearance.
Will tubular control arms fit with stock spindles and springs?
Most tubular control arms are designed as direct bolt-in replacements for stock spindles and springs. However, some aftermarket arms may require specific spindles or have different ball joint tapers. Always check the manufacturer’s fitment notes before purchasing.
How often should I grease polyurethane bushings?
Polyurethane bushings should be greased periodically to prevent squeaking. Many brands recommend greasing them every 5,000 to 10,000 miles or at each oil change. Some arms come with grease fittings to make this easier.
Our Verdict
After researching and comparing the top options, our top pick is the CPP Tubular Upper and Lower Control Arm Set for its excellent balance of performance, durability, and ease of installation. The runner up is the UMI Performance 2214 Tubular Control Arms, which offer greasable bushings and great value for the price. Both are solid choices for upgrading your tri five’s suspension.
