Dirt King Performance Lower Control Arms | Toyota 4Runner (2003-2024)

The Dirt King performance lower control arms were developed to withstand off road abuse and not compromise the vehicles on road driving characteristics. The most vulnerable suspension component on the 4Runner's are the lower control arms. The Dirt King control arms have additional ground clearance and include 1/8 inch aluminum skid plates for added protection. If there's any major contact the internal ribbed design keeps the crucial parts intact so your not left stranded on the trail.

The outer pivots on the lower control arms utilize heavy duty Moog ball joints which are low maintenance and easily serviceable. Controlled side by side testing was done between Moog ball joints and the industry standard 1 inch uniball for the outer pivot. The result was better on road tracking with the Moog ball joints. Other benefits include a sealed housing to eliminate noise, longer life span, and readily available at auto part stores.

Delrin bushings were chosen for the inner pivots after weighing all the pro and cons between vulcanized rubber bushings, poly bushings, and uniballs. Here are some of their major flaws; vulcanized bushings restrict the amount of articulation, poly bushings are too soft for the amount of force on the lower control arms causing premature wear and noise, uniballs quickly become contaminated with dirt making them noisy and they're also expensive to replace.

Additional features on the Dirt King lower control arms include recessed shock mounting with a drain hole and accepts all types of shocks and struts. It also accommodates for bump stops and limit straps. Progressive steering stops limit the steering throughout the suspension cycle to allow for maximum steering without over articulating the CV's or tie rods. This product is a direct bolt on application with all necessary hardware included. The arms are coated with a durable black powder coat and all the wearable components are replaceable for a product that will last a lifetime.

Installation

The Dirt King Performance Lower Control Arms install as a direct bolt-on replacement using supplied hardware — no welding or frame modification is required. Simply remove the existing lower control arms and install the Dirt King units, using the provided grease fittings to service the bushings prior to final torque. Once installed, verify suspension travel, alignment, and clearances before full use. Professional installation and post-install alignment are strongly recommended to maintain proper suspension geometry.
