UMI Performance 65-66 GM B-Body Adjustable Upper Control/Trailing Arm

Upgrade your GM B-Body's rear suspension with UMI Performance's adjustable upper control arm. This direct replacement for the factory arm minimizes wheel hop, improves cornering, and helps track consistency.

Featuring on-car adjustability using a 4140 heat-treated adjuster, this control arm allows for easy pinion angle adjustments without removing the arm from the vehicle. The adjustment can also eliminate the use of shims during installation.

  • On-car adjustability using a 4140 heat-treated adjuster
  • 4140 Chrome-Moly tube adaptors
  • TIG welded construction
  • Grease-able Energy Suspension polyurethane bushings
  • Brilliant durable powder coat
