What is the main benefit of using adjustable control arms?

Adjustable control arms allow you to fine-tune your rear suspension geometry. This includes adjusting the pinion angle for better drivetrain performance and adjusting the rear end position for improved tire clearance, especially with larger aftermarket wheels and tires.

What makes the Teflon-lined rod ends important?

The Teflon-lined spherical rod ends eliminate the binding often found in stock rubber bushings. They also act like solid bushings in drag racing applications, reducing deflection and improving the responsiveness of your rear suspension.

Does this kit come with all the necessary hardware for installation?

The manufacturer's description does not specify if installation hardware is included with this control arm kit. It is recommended to refer to the manufacturer's installation instructions for a complete list of included components and any additional hardware that may be required.

Product Details

This kit from UMI Performance gives you a set of adjustable upper and lower rear control arms, along with high-quality Teflon-lined spherical rod ends. These components are designed to replace your stock rear control arms on 1971-1975 GM H-Body vehicles, including your 1975-1980 Oldsmobile Starfire. By swapping out the old arms, you'll eliminate rear suspension bind, allowing your suspension to move more freely and improving overall articulation. This means better traction and less of that annoying wheel hop when you accelerate hard.

The adjustability built into these arms is a real game-changer for performance builds. You can fine-tune the position of your rear end, which is super helpful if you're fitting larger tires or installing an aftermarket rear axle. The upper control arms are specifically designed so you can set and adjust your vehicle's pinion angle, which is crucial for getting the most out of your drivetrain, especially in drag racing applications where reducing bushing deflection is key. These arms offer a street-able setup that still performs well when you hit the track.

When installing these on a 1975 model, it's a good idea to double-check if your specific vehicle uses upper control arms or a panhard bar setup, as some 1975 H-Bodies were configured differently. This kit is a solid option for anyone looking to improve their vehicle's rear suspension performance and handling.
