Better Launches. Replace your upper control arms with a set of J&M Mustang Rear Upper Control Arms for better, faster launches and to eliminate that uncomfortable feeling of "wheel hop" under heavy acceleration or braking.
Better Than the Competition. Unlike other products, the J&M Rear Upper Control Arms use a patented design to keep your Mustang's rear end planted when you mash the gas on the starting line while also improving your handling. Their unique 3-piece "Poly Ball" bushing allows your control arm to move freely when you're carving the corners but keeps it stiff when you're romping on it on the strip or slamming on the brakes. It's truly the best of both worlds.
Made to Last. Everything about these control arms is designed to last - J&M is so confident in their bushing design, they back them with a lifetime warranty should they need to be replaced. The control arms are made from round tubing for strength and finished with a gloss black powdercoat for durability and good looks.
Application. These J&M Rear Upper Control Arms are specifically designed for use on the 1979 to 2004 Mustangs with a solid rear axle, not intended for use on 1999-2004 SVT Cobra's with IRS.
