Truck owners, if you're lifting or leveling your GM 1500, these Pro Comp control arms are a massive upgrade over stock. The factory control arms just can't handle off-road use - weak ball joints and stamped steel construction fail when you need them most. These Pro Runners feature oversized stainless steel FK uniball joints that are way stronger than factory ball joints. The 1.25 inch chromoly tubular construction is built to take punishment, and the reinforced pivot bushing mounts eliminate flex during extreme suspension cycling. The PTMeg pivot bushings come with zerk fittings for easy maintenance, and the black powder coat finish looks tough and lasts. Includes billet machined dust caps to keep dirt out of the uniballs. Whether you're hitting trails, towing heavy loads, or just want better handling, these control arms transform your truck's performance. Installation is straightforward if you know what you're doing, and the difference in ride quality and durability is immediately noticeable. Your truck will thank you!
