TeraFlex Bump Stops

TeraFlex Bump Stop Kits add additional protection to your suspension over the factory bump stops, which can deform during hard compression and suspension movement.

Our innovative bump stops meet the demand for 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 the driver's ability to maintain vehicle control as well as reduces the risk of bending an axle housing tube. These maintenance-free bump stops don’t require any adjustment or tuning.

Proper bump stop length and/or bump stop strike pad height is crucial for preventing damage to axle housing tubes, suspension components, shock absorbers, and fenders.

1958250 – JK: SpeedBump & Progressive Bump Stop Kit – Front & Rear (3–3.5” Lift)

FEATURES/BENEFITS:

  • Vehicle-specific tuned for high-speed performance

SpeedBump Bump Stops

1958600 – JK: SpeedBump Bump Stop Kit – Front & Rear (6" Lift)

SpeedBump Bump Stops 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.

FEATURES/BENEFITS:

  • Self-lubricating Delrin acetal resin polymer shaft withstands 1,000s of continuous cycles without wear or abrasion
  • External shaft seal prolongs shaft life by wiping and cleaning the shaft to prevent contaminants from entering the housing
  • Simple installation — no welding required*

 

Progressive Bump Stops

1969200 – JT: Progressive Bump Stop Kit – Front & Rear (0–4.5” Lift)

Progressive Bump Stops are constructed from a performance-tuned high-density 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.

FEATURES/BENEFITS:

  • Microcellular Progressive Bump Stops simply pop into the existing factory locations
  • Replaces factory foam bump stops
  • Performance-tuned closed-cell nitrogen charged microcellular polyurethane technology
  • Simple bolt-on installation
