New upper double-adjustable rear control arms for '78-'87 GM G-bodies with special Polyurethane bushings. This "double-adjustable" style is better than just being "adjustable", by allowing adjustments in length WITHOUT removing either end from the car. We have taken the best characteristics from the many different designs available and wrapped them all up into one, and included several improvements. The most noticeable improvement is our much bigger 1.0" diameter CNC threaded center adjusting screw, compared to others with a 3/4" diameter. Not only does this improve upon strength, but it also improves the overall stiffness of the control arm. This aids in keeping the rear of the car level under acceleration, and with handling characteristics. This also allows for much larger 1.0" locking nuts (1.5" across flats) to be used. These larger nuts provide a drastically improved locking force, which ensures that they stay just the way you set them for many years to come. The center adjusting screw and locking nuts are all plated for rust prevention and appearance.
They come equipped with both straight and custom 45 degree grease fittings to allow easy access on all cars. The grease enters an area between the two poly bushing inserts, and is directed to the inner spacer. Once there, the grease coats the inner spacer 360 degrees around, through several grooves in the poly bushings. This will eliminate any possible binding or squeaking, and allow quicker movement for improved performance. Also included with every pair of control arms is a pair of custom poly bushings with grease fittings, for the top ears/brackets on the rearend housing. These custom new control arms will allow enough flex for comfortable street driving, but also be stiff enough to perform under the most severe racing conditions. These are a direct bolt-in replacement for the stock lower rear control arms on the following vehicles:
* '82-'87 Buick Regal (GN, GN-X, T-Type, WE-4)
* '82-'87 Chevy El Camino
* '82-'83 Chevy Malibu
* '82-'88 Chevy Monte Carlo
* '82-'87 GMC Caballero
* '82-'88 Olds Cutlass RWD
* '82-'86 Pontiac Bonneville
* '82-'87 Pontiac Grand Prix
They will provide more stability for better handling, quicker acceleration and lower 60 ft. times, and are designed to work great on the street & track without any compromises in either area. The following are details and features included with each pair:
1.) CNC machined/threaded round steel tubing
2.) Super thick 1/4" steel U-bent brackets with extra clearance
3.) Special welding equipment & process for superior strength
4,) Black powdercoat finish, best heavy-duty coating available
5.) Custom Polyurethane bushings from Energy Suspensions*
6.) Special grease grooves in bushings and grease fittings included
7.) Custom machined inner steel spacer for improved performance
8.) Custom bushings #0500 for top ears/brackets on rearend housing
9.) All necessary grade 10.9 hardware to install, plated for rust prevention
10.) Easy to upgrade/install, with detailed instructions included
11.) One Year limited warranty, applies under racing conditions
12.) Comes complete and partially assembled, ready to install
Also included are instructions for setting and checking the pinion angle, along with recommendations for various applications. We believe these are by far the strongest and highest quality available anywhere, and will outperform other adjustable control arms available at much higher prices. They are an excellent upgrade from the stock components, and are designed for street and track at any HP level. As noted above, there are many improvements even over the stock arms that have been boxed with upgraded Poly bushings. Our design will transfer power to the ground quicker than other arms with Poly bushings, and ride much smoother on the street than "rod-end" type or solid bushing styles. Our new control arms have been proven by Terry Houston at 8.60's and over 160 mph.
We also have a NON-adjustable style of upper rear control arms available for the above applications.
