Overview 

Transform your 5th Gen Toyota 4Runner into the ultimate overland adventure vehicle with the Old Man Emu BP-51 Suspension Lift Kit. Featuring ARB's revolutionary Internal Bypass shock technology, adjustable compression and rebound damping, and suspension tuned for loaded expedition vehicles, the BP-51 delivers exceptional ride comfort, superior off-road control, and unmatched reliability for long-distance travel.

Engineered for serious overland travelers and expedition enthusiasts, the Old Man Emu BP-51 Suspension Lift Kit is ARB's flagship suspension system for the 2010-2024 Toyota 4Runner.

Unlike conventional suspension systems, the BP-51 utilizes Internal Bypass shock technology that provides precise damping throughout the suspension's travel. This advanced design delivers exceptional ride comfort on the highway while maintaining outstanding control across rocky trails, washboard roads, forest service roads, and remote backcountry terrain.

Designed specifically for vehicles carrying additional constant weight, the BP-51 performs exceptionally well with rooftop tents, steel bumpers, winches, skid plates, drawer systems, recovery equipment, refrigerators, and camping gear. Adjustable compression and rebound settings allow drivers to fine-tune the suspension to match their driving style and vehicle setup without sacrificing comfort or control.

Whether you're exploring national parks, tackling remote mountain trails, or embarking on cross-country overland expeditions, the Old Man Emu BP-51 delivers the confidence, comfort, and durability trusted by adventurers worldwide.
