The UMI tubular trailing arm for 1997–2005 GM W-Body applications is engineered to outperform stamped stock arms by reducing flex and bushing deflection under load. Constructed from 1.250" x 0.120" DOM mild steel tubing with CNC-machined bushing holders, it includes grease-able polyurethane bushings, TIG-welded joins and a durable powder coat. The design lowers body roll and improves handling consistency for spirited driving.
