Product Description

The Ridetech 11236699 is a pair of adjustable rear upper StrongArms built as a direct replacement for the stock trailing arms on 1964-1967 GM A-Body cars, spanning the Chevelle, Cutlass, El Camino, F-85, 442, GTO, LeMans, Malibu, Skylark, Special, Sportwagon, Tempest, and Vista Cruiser. If your stamped OEM control arms are holding back the rest of your suspension work, these tubular StrongArms are built to finish the job right.

At the heart of this upgrade is Ridetech's R-Joint Technology - a revolutionary rod end design that combines low-friction movement, full-range articulation, lateral stability, and quiet operation in one bearing. The new adjustable rod ends help eliminate bushing bind, which can otherwise hinder ride quality and performance, while the R-Joint's precision-machined 17-4 stainless steel housing and RTX10 composite cage deliver consistent, maintenance-free movement that shrugs off water, dirt, and grit.

These arms were developed and refined by Ridetech in Jasper, Indiana on an actual running, driving vehicle, ensuring they properly address real-world fitment issues like ShockWave installation clearance, ball joint binding, and frame clearance - problems that stock arms simply weren't designed to handle. Finished in durable black powdercoat over tubular steel construction, these StrongArms are a precision-engineered upgrade for anyone serious about their A-Body's rear suspension performance.
