BMR Upper Control Arms w/ Spherical Bearings, "On-Car" Adjustable (1978-1987 GM G-Body)

Factory control arms are marginal at best. Bushing deflection combined with control arm flex creates erratic handling and inconsistent rear end stability when subjected to the added loads of drag racing or performance driving. BMR control arms are manufactured from large diameter DOM or rectangular tubing to eliminate this flex and stabilize the suspension, allowing the suspension to do it's job more efficiently.

The lower control arms are available with or without swaybar mounting provisions. Our boxed lower arm is manufactured from 1.5" x 3" rectangular tubing and has reinforced swaybar mounting holes. This version is available for the street with greasable, fluted polyurethane bushings or for the track with bulletproof QA1 Teflon-lined spherical bearings.

For applications not requiring a control arm mounted swaybar we also provide chrome moly adjustable lower control arms. These come equipped with QA1 XR series 3/4" Teflon lined HD rod ends.

Upper control arms are available in either fixed length or adjustable versions, with either greasable, fluted polyurethane bushings or QA1 Teflon-lined XR series spherical bearings. Adjustable uppers allow "on-car" pinion angle adjustment by simply loosening the jamnuts and turning the adjuster. No need to unbolt the control arm. These adjusters are by far the strongest in the industry. Made from 1-1/8" CNC machined steel and zinc plated for corrosion resistance, they truly are overkill!

All control arms available in Black Hammertone or red powdercoat finish.
