Control the hardest hits
Every big compression ends at the bump stop. TeraFlex bump stops meet that moment with progressive resistance, so trail drops and deep potholes finish with a cushion instead of a jolt.

Tuned to your tires
Extensions, shims and SpeedBump spacers let you set how far the axle can travel for the tire size and fender clearance on your build.
Push harder, land softer
With the end of travel under control, you can carry more pace over rough ground and keep the ride livable on the drive home.

Frequently Asked Questions
Straight answers on specs, fit and support
Why upgrade the bump stops on a lifted Jeep?
A lift and bigger tires change how far the suspension can compress before something makes contact. Upgraded bump stops control that last bit of travel and soften the hit.
How do I know how many spacers I need?
TeraFlex publishes a spacer guide based on tested tires, trim and engine. Follow it, then cycle the suspension to confirm clearance with your tires.
Does my trim or engine change the setup?
Yes. Rubicon fenders allow more up-travel than Sport and Sahara fenders, and diesel and 392 models have minimum spacer requirements.
Is any cutting involved?
The SpeedBump kits require trimming the jounce tube and drilling a new hole. The progressive bumpers, extensions and shims bolt in.
Can I combine extensions and shims?
Yes. TeraFlex designs the strike pad extensions and shim kits to be stacked to fine-tune bump stop height.
What warranty covers bump stops?
TeraFlex lists bump stops under lifetime coverage against defects in materials and workmanship for the original purchaser.

Quality bump stocks, easy to install
Way nicer than bump stock extension blocks. Oxidized red after a few months to match my shocks haha! Make sure to remove the plastic inserts on the fronts. They wouldn't go in with it on.

Better Material
Not sure how this will affect the vehicle, but the material is better in these bump stops. Fit was easy just use some pressure and they pop into place.

Keeps my tires from rubbing!
Installed after Mopar lift and 37s. Keeps the tires from rubbing when flexed. Easy to install.

Made for the job.
I installed these with the Teraflex spacer lift and it was a breeze. They seem very well made and get the job done.

works good
Installed bump stops with my lift kit. The quality and fit are great. Spray some silicone lube on them before install, takes a bit of effort but with a push and twist they went in without too much trouble
