Description

The UMI Performance 4017-B is a set of adjustable upper control arms designed for the rear of GM A-Body vehicles. These arms are constructed from durable 4140 chrome moly steel with TIG welded construction. They feature on-car adjustability for easy pinion angle adjustments and Teflon-lined spherical rod ends to prevent binding.

The control arm mounting points include CNC machined mild steel and 4140 chrome moly tube adaptors, along with a high-strength 4140 chrome moly heat-treated adjuster. The product is designed and manufactured in the USA.
