Sold as one pair, two bump stops COMPATIBLE VEHICLES Toyota Tacoma Gen 1, 2, 3 Toyota Tundra Gen 1, 2 Nissan Frontier Gen 2 Nissan Titan Gen 1, 2 PRODUCT HEIGHT Regular Length Shocks: 76 mm Extended Travel Shocks: 102 mm HARDWARE INCLUDED Bottom plates included as pictured. The faster you hit our parts, the harder they push back. Helping to absorb suspension travel and provide a "bottomless" feel when you're pushing the limits. Low speed Dynamic response On low speed compression, our bump stops allow full suspension travel, while preserving a hard stop to prevent overtravel. Air is forced through the internal ports, reducing the total response force, and enabling a softer ride. High Speed Dynamic response On high speed compression, our bump stops generate internal air pressure, increasing their force feedback by up to 37%. This provides maximum support when you need it. Rebound rate is controlled, while air is pulled back into the part as it returns to shape. This reduces the workload on the shock absorbers to settle rebound speed. Performance: Unmatched energy absorbtion We reached out to an independent third party [Midwest Suspension LLC] to test our product vs our competitors to fully understand how they all stack up, using industry leading test hardware to study their dynamic, variable rate nature.
