Description
Control your Control Arm Flex. J&M's control arms increase straight-line traction and improve cornering performance. Their exclusive design allows your lower arms to articulate during cornering but stay stiff under acceleration.
Better than Stock. Handling characteristics like wheel hop, rear end instability, or even snap oversteer can be the result of the OEM control arm design. Get rid of it with these arms.
Better than the Competition. These arms feature a steel inner ball surrounded by polyurethane outer cups. The result is great traction during straight-line acceleration and predictable grip during hard cornering. And unlike other arms, they don't put stress on your torque box.
Quality. J&M's arms are made of rugged 1 1/4" threaded bungs and adjuster. Manufactured from round tubing, they're lighter, stronger, and more resilient to bending and torsion compared to rectangular or square tubing. With custom made pinion snubbers, these upper control arms are the perfect suspension upgrade.
