Revamp your classic cars handling and stability with our
Massive SpeedCOMPETITIONSeries With factory Sway bar mounts

Stock lower rear control arms on a GM A-Body are of an extremely flimsy stamped sheet metal construction. Soggy rubber bushings complete the recipe for unwanted wheel hop, deflection and flex.

Massive has created a stronger solution. Huge 1.5" heavy wall steel tubing CNC cut and jig welded for a perfect fit. It can handle the highest HP load with ease. They reduce control arm flex during hard cornering and acceleration. Durable and stable polyurethane bushings transfer your hard earned torque where it belongs - the pavement. Prominent Massive logo so people know your using the best. As usual, these arms are MADE 100% IN THE USA - so you know your getting the best.

These armsDO HAVE sway bar hook up provisions. If your car did not come with a bar from the factory, you've eliminated it, or you have an aftermarket bar that moves the end link hook up to the chassis, please see our other items for a hook up free set (they cost less dough!!!). https://massivespeedsystem.com/products/massive-speed-competition-series-lower-control-arms-64-72-gm-a-body-with-out-sway-bar

Includes Massive's HARDCORE HARDWARE kit - the competitors DON'T. Only the finest 170,000 PSI Grade 8 bolts with Nylock nuts and plated washers. Strong enough for all power levels and replaces your weak rusted stock stuff.

Get ready to rock your 60 foot times!!!
