Product Description

Replace your Mustang 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.

Bushing Lubrication
The suspension bushings included with this part can only be lubricated with PTFE grease, also referred to as "Marine Grease". PTFE grease is a very sticky, opaque grease that is water proof and will not degrade the bushing material. If lubed properly at installation, these bushings will not need to be lubricated again. Use of any other grease on these bushings will cause the bushing to fail and any bushing warranty to be voided.
