J&M Products – 1982-2002 Camaro / Firebird On Car Adjustable Lower Control Arms 3 Piece Poly-Ball Bushings – Black
Part # 23814B – 3 Piece Poly-Ball Bushings
Made In USA!
Replace those weak, factory stamped lower control arms with J&M Products heavy duty tubular on car adjustable arms. These are a direct bolt-on replacement that minimize wheel hop, improve cornering, lowers ET’s and greatly help your track consistency. J&M Products control arms are constructed from 1.25″ U.S. made DOM steel tubing, 1045 steel threaded tube adaptors (stronger than chrome-moly), completely CNC machined and fully pulse welded for outstanding strength. J&M Products control arms also feature easy adjustment using a super high strength 4340 alloy steel turnbuckle that has been heat treated to the same strength as a grade 8 bolt for superior strength over any other brand turnbuckle on the market. J&M Products also doesn’t cut the threads like our competition but we choose to roll our threads just like rod ends and high quality ARP hardware.

Bushing Design:
The control arm bushings found in the F-Body automobiles can have a significant impact on the vehicle’s ride, comfort, handling, acceleration, noise and vibration. When the car leans (i.e., rolls) in a turn, one side of the chassis moves upward relative to the rear axle, the other side moves downward, and the control arms must twist to allow for the axle to articulate. This causes the control arm bushings to bind. If this bind becomes excessive, it will raise the rear wheel rate and produce sudden, uncontrolled, undesirable changes in handling (e.g., snap oversteer).
Chevrolet minimizes this suspension bind by using compliant rubber bushings in both lower control arms. These relatively “soft” bushings help accommodate the necessary motion of the control arms during body roll. However, the rubber bushings do not provide much in the way of forward and aft support, which can cause wheel hop during hard acceleration and braking.

It has become common practice to replace the stock rubber control arm bushings with solid or two piece polyurethane bushings to resolve the shortcomings of the soft rubber bushings. Hard polyurethane bushings eliminate wheel hop, reduce axle deflection, and improve rear straight line grip. However, the downside of common aftermarket bushings such as delrin, steel, stiffer rubber, solid or two piece polyurethane bushings is they prevent the necessary movement of the control arms during body roll, which in turn produces significant binding in the suspension when the vehicle is cornering. The polyurethane bushings also place unnecessary high stresses on the torque boxes, which are the attachment points for the control arms to the chassis. Standard aftermarket control arms do not allow for rotation of the control arm during cornering because of the stiffness of the bushings.

J&M Products Solution:
We at J&M Products designed and built a Camaro/Firebird lower control arm using 1.75″ high strength round tube to eliminate the unwanted uncontrolled control arm flex. Round tubing is harder to work with but has many other advantages over square or rectangular tubing. It is stronger in bending, torsion, and also lighter than square or rectangular tubing.

We then solved the shortcomings of the factory rubber and other aftermarket polyurethane and st
