The Old Man Emu BP-51 Rear Shock Absorber BP5160032 is designed for Jeep Wrangler JK owners who demand maximum rear suspension performance from lifted and heavily equipped vehicles. Built with advanced internal bypass technology, this shock provides position-sensitive damping that automatically changes through the stroke — offering comfort over small bumps and strong control during large suspension movements.
In real-world driving, this translates into smoother ride quality on minor irregularities and increased bottom-out resistance when the suspension is heavily loaded or driven aggressively off-road. The progressive damping curve helps keep the rear axle controlled and stable across varied terrain.
A key feature is the external remote reservoir, which increases oil volume and improves cooling efficiency. This reduces damping fade during long off-road runs and repeated impacts. The BP-51 system also offers independent compression and rebound adjustment, allowing precise tuning based on lift height, rear load, accessories, and driving style.
This makes the BP5160032 an excellent choice for overland builds, expedition vehicles, and performance-oriented Wrangler JK setups that require consistent rear-end control and adjustability.
