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 and FJ Cruiser's are the lower control arms. The Dirt King control arms have additional ground clearance and include 1/8" aluminum skid plates for added protection. If there's any major contact the internal ribbed design keeps the crucial parts intact so you're 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" 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.
