Description

This new replacement rear control arm mount replaces the stock control arm mount that attaches the rear upper control arm to the vehicle chassis. This item works excellent when the factory mount is too rusted to re-use or when installing a 12-bolt 4-link set-up into a 3-link equipped vehicle. Replacement bracket is CNC machined from 0.188" thick steel plate, precision bent and supplied with a bright red or gloss black powder coat. Item includes new grade 8 hardware to complete installation.
