Adjustable Rear Lower Control Arms with Poly & Del-Sphere | 1978-1987 GM G-Body

Application: 1978-1987 GM G-Body – Regal, Malibu, Monte Carlo, etc.

Part# 217

These adjustable rear lower control arms for the 1978-1987 GM G-Body cars outperform the flexible, heavy, stamped steel arms and soft rubber bushings that come from the factory. Eliminate wheel hop and increase traction with an easy bolt on installation.

The adjustability feature allows for fore and aft centering of the rear axle housing to correct for factory tolerances, this also allows for fore and aft movement of the entire rear axle assembly to provide for adequate tire clearance when running large tires.

One end is fitted with a grease fitting for easy lubrication of the fluted polyurethane bushings. The other end features a Del-Sphere™ pivot joint that provides for 28° of “bind-free” handling performance. The polyurethane bushed ends are mounted onto the chassis (floor) mount to absorb road noise. These combo ended LCAs will wipe out most bind, yet keep the noise increase minimal for a street driven car.

They’re available powder coated in your choice of bright red or gloss black for a brilliant and durable finish.

Del-Sphere™ Pivot Joints:

The Spohn Performance Del-Sphere™ pivot joint solves the shortcomings of the factory rubber and aftermarket polyurethane bushings. Our Del-Sphere™ pivot joint incorporates a spherical ball which is surrounded by Delrin® bushing cups.

Think of the Del-Sphere™ pivot joint as a Delrin® bushed spherical rod end. After over a year of R&D testing here at Spohn Performance on a streetable spherical joint the Del-Sphere™ pivot joint is the final result. Designed and manufactured exclusively by Spohn Performance, we have taken street suspension performance to the next level.

Our Del-Sphere™ pivot joint features a one piece forged and heat treated 4130 chrome moly housing, a heat treated and chrome plated chrome moly spherical ball, Delrin® bushing cups, heat treated retainer washer and snap ring, heat treated and chrome plated chrome moly threaded adjuster ring, an external grease fitting, and a beautiful silver zinc plated housing finish.

The Delrin® bushing cups absorb shock and road noise so you get the quiet and smooth ride of a bushing as well as 28° of rotation! Our Del-Sphere™ pivot joints will always ship to you fully assembled, however, we also offer an optional adjusting tool that will allow you to do two things.

First, you can disassemble the Del-Sphere™ pivot joint for cleaning, inspection, etc. Second, you can adjust the amount of tension on the spherical ball. The amount of tension can be easily adjusted by using our optional adjustment tool to tighten or loosen the end retainer ring.

What that means is if over time and miles the tolerances open up you can simply re-adjust the retainer ring and have your pivot joint as tight as it was the day it was brand new. We doubt you’ll ever need to replace the Delrin® bushing cups, but they certainly can be. Unlike a spherical rod end, the Del-Sphere™ pivot joint is 100% rebuildable.
