"The Timbren active off-road bump stops help you take control of your suspension travel. Unlike factory bump stops, these are designed with a progressive spring rate that absorbs the energy when your vehicle bottoms out and returns it to the axle in a more controlled manner, creating a smoother ride whilst in bumpy terrain. These Aeon® rubber springs possess a unique quality called ""hysteresis."" Simply put, they act as a shock absorber. They’re particularly effective when used as a helper spring for their self-damping quality. With these bump stops, you'll never have to worry about checking pressure, running air lines or watching for leaks like you need to with airbags; just install and forget. Timbren's progressive spring is built with the toughest material available in the industry and is suitable for off roading in any weather or geo-location. These bump stops have been used for over 50 years with Timbren's innovative manufacturing technology and are an affordable alternative to some of the other options available on the market. | Timbren Off-Road Bump Stops ABSTRFK"
