SPC Performance 55-57 Chevrolet Tri-5 Upper Adjustable Control Arm

Starting with a 1/2" taller ball stud than stock, these SPC Performance upper adjustable control arms are built to give your classic Tri-Five Chevy a more modern feel on the road. This unique, patented design offers the most adjustability and best clearance available for these iconic vehicles. By allowing you to dial in both caster and camber, you can significantly improve the suspension geometry, leading to a more stable and predictable ride, whether you're cruising daily or hitting the track.

These arms are constructed from forged steel for strength and durability. The ball joints are designed to be greaseable and fully rebuildable, meaning you can maintain them for long-term performance. SPC also offers optional OE length and 1/4" extended studs, allowing for further fine-tuning of your suspension geometry to match your specific driving needs. Sold as a pair, these control arms are a key component in transforming the front suspension of your classic American muscle car.

To get the most out of your suspension upgrade, consider pairing these upper control arms with SPC's available lower control arms. This comprehensive approach can help you achieve a truly modernized suspension setup for your Pro Touring build, track car, or daily driver.
