Whether you're classic B-Body is a restoration project, street car, cruiser or even a drag racer the UMI Performance control arms are an excellent upgrade. This boxed control arm set is a direct bolt-on designed to replace the stock stamped steel control arms. Over time stock control arms rust weakening them, the OEM bushings dry rot, harden and crack decreasing your ride quality and vehicle performance. This new set-up is supplied with grease-able Energy Suspension polyurethane bushings designed to improve ride quality and overall performance. The polyurethane bushings reduce bushing deflection found with stock rubber bushings helping to reduce body roll and increase traction by eliminating wheel hop. The construction of the control arms features 0.120" wall thickness rectangular tubing with CNC machined drawn over mandrel bushing holders and MIG welded end caps to keep out unwanted road debris. Control Arms feature correct spring perches to except the factory spring. Stock hardware can be used or a new hardware kit can be purchased below.

This kit includes all needed Grade 8 hardware for installing (1) set of lower control arms. Note: This hardware kit does not include a new shock mount bolts; you must re-use the OEM bolt. This kit does include new nuts for the shock mount bolt.
