Upgrade Your Chevelle, GTO, Skylark, or Cutlass With Our A-Body Rear Upper Control Arms

If you’re driving a GM A-body—Chevelle, GTO, Cutlass, or Skylark—you already know the factory triangulated four-link rear suspension falls short when it comes to high-performance handling, but our GT Series rear upper control arms offer an easy fix. Designed to eliminate the articulation issues of the stock setup while improving stability, traction, and responsiveness, these arms are crafted from TIG-welded 4130 Chromoly for exceptional strength and durability. Available with low-friction rod ends that maximize articulation and minimize deflection, friction, and weight, they’re perfect for performance focused builds. Precision CNC-machined spacers ensure a perfect fit, and the durable satin black finish delivers a sleek, high-end look—giving your A-body the rear suspension performance and style it deserves.

Why We Avoid Jackscrews, And Why You Should Too

Some aftermarket companies use jackscrews in their upper control arms to make pinion angle adjustments easier. But here’s the problem:

  • Jackscrews add weight and reduce strength.
  • Pinion angle adjustments are rare; you’ll likely set it once and forget it unless you change ride height, transmissions, or rear ends.

That’s why we prioritize strength and weight savings over unnecessary complexity.

Part of Our GP-R Series – Race-Bred Performance for the Track
These rear lower control arms are part of our GP-R Series—engineered for uncompromising performance on the track and in competition. Built for racers and hardcore enthusiasts, the GP-R line is all about maximizing capability under extreme conditions. Whether you’re chasing lap times, dialing in your setup for time attack, or building a no-compromise pro touring machine, GP-R components deliver the strength, adjustability, and precision you need to dominate.
