The Rock Krawler rear lower long arm is a replacement lower control arm for 2018+ Jeep Wrangler JL two-door and JLU four-door models. It extends the lower link length to correct axle location after a lift and helps restore proper rear suspension geometry. Install it with other long-arm components to maintain alignment and predictable handling under load.
