Rear Adjustable Control Arm Kit

The Opt Offroad rear adjustable control arm kit offers a high-strength solution for 1996–2002 Toyota 4Runner owners looking to improve suspension geometry on lifted rigs. Designed to support up to 4 inches of lift, these arms ensure precise alignment correction, effective pinion angle adjustment, and improved axle positioning, all while maintaining factory-like on-road manners. Built for durability, the kit uses 1.625-inch DOM steel for lower arms and 1.0-inch DOM steel for upper arms, finished with a textured black powder coat for corrosion resistance. The integration of custom Johnny Joints® at all pivot points provides maximum articulation and minimal maintenance requirements. Each arm features machined wrench flats for 1.25-inch and 1.5-inch wrenches, simplifying adjustments in the field. This kit is compatible with factory bolt hardware, which must be reused as no new hardware is included. For enthusiasts building dedicated trail rigs, the manufacturer recommends pairing these control arms with optional lower and upper link reinforcement kits.
