78-88 UMI Adjustable Upper A-Arms (pair)

Adjustable tubular upper control arms (pair) by UMI are designed to excel in all forms of racing. The race quality rod ends provide shim-free camber and caster adjustment along with ultimate smooth travel. This arm features a relocated ball joint pad to increase caster and improve stability and steering feel as well as a shortened cross shaft to ball joint distance.

Features include:

  • CNC laser cut ball joint mounting pad.
  • 0.120” wall thickness 1.250” diameter DOM tubing.
  • TIG welded for superior strength and clean looks.
  • 4130 chromoly cross shafts, CNC machined & zinc plated.
  • Polyurethane bump stops included.
  • Travel limiting bolt compatible.
  • Direct bolt-in compatible with factory or UMI lower a-arm.
  • May also work in conjunction with other lower a-arms and/or spindles (contact us to discuss).
  • Package includes recommended alignment specs and detailed installation instructions.


Note: Standard ball joint will usually require the use of taller spindles.
