Why Core 4X4 Control Arms?

Adjustable control arms allow you to easily re-center your axle, adjust your pinion and caster angles, and allow your axle to move freely on and off the road without unnecessary binding. New control arms with solid bushings can also help with problems like death wobble and uneven tire wear. All our control arms are built with high-quality materials right here in the USA and carry our unique "you manage to break it, we replace it" warranty.
