So what are we talking about here with Teraflex Speed Bumps? What are they, what's the advantage? Their purpose is to reduce suspension compression impact. In simpler terms, they act to keep your axle from slamming into the frame during big impacts, thus reducing the chance of bending or damaging the axle housing tube. They act like a shock absorber, working in a progressive manner to absorb large impacts, slowing the axle down during the compression stroke.
Features & Benefits
- Jk/Jku specific tuned for high-speed performance
- Absorbs large impact energy progressively during compression to prevent bent axle tubes
- Quiet movement and function (no pad slap)
- Maintenance free, all composite construction
- Resistant to all types of environmental conditions
- Subzero temperature flexibility reduces fatigue
- Compatible with all suspension systems that retain factory axle spring mounting locations
- Lifetime guarantee
Here's a walk through the install on Rubi. This install requires removing the factory bump stop bell with no welding required. This was my previous set-up. You can clearly see the factory bump stop.
Let's get everything out of way...
Next it's time to modify the bump stop housing to accept the speed bumps...
My lower bump stop pads had a corroded bolt we ended up cutting off. With the new set-up, I will be adjusting how many pads I will run. Teraflex gives a recommendation based on lift height, wheel size as a starting point.
Here is the finished install...
Here's a look at the SpeedBumps in action...
What I really like about these is knowing if I'm surprised by a really big suspension bottoming bump, I have the SpeedBumps to take the hit and protect the axle. These have run completely silent, both on and off road. Another great TeraFlex product!
