SPC Performance 58-64 Chevrolet Bel Air / Caprice / Impala Upper Adjustable Control Arm

Starting with a 1/2" taller ball stud than stock, these SPC Performance upper adjustable control arms are designed to significantly improve the camber curve on your classic 1958-1964 Chevrolet Bel Air, Biscayne, Caprice, or Impala. This unique, patented design offers the most adjustability and best clearance available for these popular classic Chevy applications, allowing you to dial in caster and camber for a truly modern suspension feel. The forged steel construction ensures a solid foundation for your front end, and the ball joints are not only greaseable but also fully rebuildable, meaning you can maintain them for long-term performance. You can further fine-tune your suspension geometry by choosing between the included extended ball studs, OE length studs, or an additional 1/4" extended stud option, which are sold separately. These arms are sold as a pair and are essential for anyone looking to transform their classic American muscle car for Pro Touring, track-ready use, or even just a more comfortable daily driver.

The adjustability range for camber and caster is ±3.00°, giving you the flexibility to achieve precise alignment settings. This level of control is crucial for optimizing tire contact with the road, especially when upgrading to wider tires or modifying your vehicle for performance driving. By allowing for more caster, you can improve steering stability and return-to-center feel, while precise camber adjustment helps manage tire wear and maximize grip during cornering. The ability to rebuild and grease the ball joints means you can keep your suspension performing optimally for years to come, making this a worthwhile investment for your classic Chevy.
