Stock stamped steel 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 additional loads of performance driving and racing.
BMR control arms are manufactured from heavy duty 1-5/8" x .120" DOM tubing with 1/4" thick mounting plates for a bulletproof combination.
These Upper control arms are equipped with double adjusters to allow easy, "on-car" adjustability by simply loosening the jamnuts and turning the adjuster. This allows you to easily adjust your pinion angle without unbolting the control arm, a convenience not offered by most.
These adjusters are by far the strongest in the industry. Made from 1-1/8" CNC machined steel and then zinc plated for corrosion resistance, they truly are overkill!
