3-Piece Poly-Ball Bushings
The J&M Poly-Ball bushing design is engineered to allow the suspension to articulate more freely than a basic polyurethane bushing setup. Reduced bind helps the rear suspension move through its intended range while maintaining improved control under acceleration and cornering loads.
On-Car Adjustability
The double adjustable design allows upper control arm length to be changed without removing the arm from the vehicle. This makes it easier to fine-tune rear suspension geometry and pinion angle as the vehicle setup changes.
Heavy-Duty Construction
J&M equips the control arm with rugged 1-inch-14 threaded bungs and an adjuster for strength in high-load performance applications. A one-piece saddle-style axle housing mount adds rigidity, while available powder coat finishes provide corrosion resistance and a clean appearance.
