UMI Performance 65-67 GM A-Body Adjustable Upper Control Arms- Poly Bushings

If you're looking to dial in the rear suspension on your classic GM A-Body, like a 1965-1967 Chevelle or GTO, getting the pinion angle just right is key. These adjustable upper control arms from UMI Performance help you do exactly that, making it easier to improve traction, reduce wheel hop, and get better performance on the street or track. They're built with solid components designed to handle the demands of a performance-oriented classic car.

What sets these apart is the on-car adjuster. This means you can make changes to your pinion angle without having to pull the control arm off the vehicle, which saves a lot of time and hassle during setup. The arms themselves are constructed from strong 0.250" steel mounting plates, with 4140 chrome moly steel used for the threaded tube adapters and the 1.000" solid adjuster. They also come with grease-able polyurethane bushings that are fluted for better grease distribution, along with new bushings for the rear end housing. The whole assembly is precision CNC machined and fully welded, then finished with a durable gloss powder coat to resist corrosion and wear.

These control arms are a solid option for anyone serious about fine-tuning their classic GM's suspension. They offer a significant improvement over stock, especially when you're trying to optimize for specific driving conditions or performance goals.
