1979-1998 Ford Mustang Street Performance Rear Lower Control Arms (Part #23857)

Street performance rear lower control arms for 1979-1998 Ford Mustang solid-axle models replace soft factory rubber bushings and flex-prone stamped arms with CNC laser-cut 2-inch round steel tubing and 3-piece Poly-Ball bushings.

Factory rubber bushings bind under roll and deflect under acceleration, which can raise effective spring rate and contribute to snap oversteer. These arms reduce bushing deflection while maintaining the articulation needed for predictable rear traction. Part # 23857. Made in the USA by J&M Products.
