Rear Lower Control Arms, Del-Sphere & Poly Bushing, 1971-1996 GM B-Body, Black 1991-1996 Buick Roadmaster

This part fits 1991-1996 Buick Roadmaster vehicles.
If youve got a big wheeled Donk, or youre laying in the weeds, then these arms have your name written all over them! Replace the factory rear lower control arms on your 1971-1996 GM B-Body with our adjustable units!
These allow for centering the rear end after lowering or lifting your ride height. They also allow for fore and aft alignment of the rear end for clearance when running larger tires and greatly increase the rear ends stability.
These are the best compromise for a combination of street driving and performance. The Del-Sphere pivot joints mount to the rear axle housing and provide for 28 of bind-free articulation, perfect for the enthusiast looking for maximum suspension articulation, while the chassis mounted fluted polyurethane bushings isolate noise, vibration, and harshness.
Tech Notes
Adjustability Ranges: OEM: 22.0 Fully Compressed: 21.125 Maximum Extended: 23.125
Rear Sway Bar: These adjustable rear lower control arms have NO PROVISIONS to mount a rear sway bar. Because the arms mount on an angle on the car, any change in length of the arm changes the positioning of the sway bar mounting holes and the rear sway bar will not line up with the holes. If you tried to adjust the length of the control arm with a rear sway bar mounted to the arm it would just bind up. If you want a rear sway bar you will need to use a rear sway bar that mounts to the chassis, not the control arms.
Rear Upper Control Arms: You will need to use Spohn SKU 634 or 635 adjustable rear upper control arms to maintain proper pinion angle.
Del-Sphere Pivot Joints: Think of the Del-Sphere pivot joint as a Delrin bushed spherical rod end. 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! Unlike a spherical rod end, the Del-Sphere pivot joint is 100% rebuildable.
