Product Description

The ARB BP5160025 BP-51 rear bypass shock is engineered for ultimate off-road control and comfort across a wide range of Toyota and Lexus 4WD platforms--including 4Runner, Prado, GX, and FJ Cruiser. Featuring a 51 mm bore, remote reservoir, and internal bypass technology, this shock delivers smooth ride quality with firm support near end-of-travel to prevent harsh bottoming.

CNC-machined from aircraft-grade 6061-T6 aluminum and Type-III anodized for rust resistance, this shock is fully rebuildable and re-valvable. With external knobs for on-vehicle compression and rebound tuning, it adapts to different loads and terrains. Designed for up to 2" rear lift (with VM80010010 kit) and including a fit kit, it's a bolt-on upgrade that maintains factory-level mounting. Backed by a 3-year Old Man Emu warranty, it offers premium durability and performance.
