These innovative TeraFlex SpeedBump Bump Stops meet the demand of high-performance driving. Composite construction combined with a progressive nature reduces suspension compression impacts and harshness when bottoming out whether driving off-road or on poorly maintained highways. Reducing this impact increases driver ability to maintain vehicle control as well as reduces the risk of bending an axle housing tube.

Other features include performance-tuned closed-cell nitrogen charged microcellular polyurethane technology that will not fade or dissipate under extended heavy use to maintain its progressive nature. This material is unaffected by temperature extremes and retains its flexibility under thermal or sub-zero temperatures.

Front SpeedBump Bump Stops also feature a self-lubricating Delrin acetal resin polymer shaft to withstand 1,000s of continuous cycles without wear or abrasion. The external shaft seal also prolongs shaft life by wiping and cleaning the shaft to prevent contaminants from entering the SpeedBump housing. The front bump stops feature a simple bolt-on installation simply requires removal of the factory bump stop bell with no welding required.

Additionally, these maintenance-free SpeedBump Bump Stops don't require any adjustment or tuning.
