Product Details

UMI Performance 402500-R adjustable rear upper control arms deliver precision pinion angle adjustment for improved traction, handling, and performance. Designed for serious enthusiasts who demand on-car adjustability without removing components, these control arms are engineered to reduce wheel hop, lower 60-foot times, and optimize power transfer to the ground.

Key Features:

  • On-car adjustability for easy pinion angle changes without removing control arms
  • CNC machined 0.250" steel mounting plates for maximum strength and durability
  • Heat-treated 1.000" solid 4140 chromoly adjusters for exceptional rigidity
  • 4140 chromoly threaded tube adapters for superior thread engagement
  • CNC machined 6061 aluminum step bushings for precise fitment
  • Greaseable Energy Suspension fluted polyurethane bushings pre-installed
  • Includes Energy Suspension rear end housing bushings
  • Durable gloss powder coat finish for long-lasting corrosion resistance
  • Precision CNC machining with fully welded construction

These adjustable upper control arms are essential for vehicles with modified ride height or performance applications where optimizing suspension geometry is critical. The unique on-car adjuster design allows quick pinion angle corrections during tuning sessions, making these ideal for drag racing, autocross, or street performance builds.
