Overview
The Rubicon Express lower bump stop, part number RE1383, is a 3.0-inch extended bump stop for coil spring applications, sold as a pair. Bump stops limit how far the suspension can compress, and these extended stops fit inside the front coil to give extra limitation for larger tires.
Based on the title, the stops are for Jeep TJ, LJ, XJ and ZJ models. The title lists TJ/LJ/XJ/ZJ, so the fitment below follows those chassis codes and their years.
- 3.0-inch extended length
- Sold as a pair
- Fits inside the front coil for coil spring applications
- Self-tapping mounting bolts included
Choosing bump stop height
Bump stops limit how far the suspension can compress, which protects the shock, the axle and the frame from hitting each other at full travel. Extended stops start working sooner, which can help on larger tires where the suspension moves further than the stock setup.
Extended stops change how the suspension behaves under heavy compression. Check that the stop does not contact the coil or other parts earlier than intended, and look at the travel left before the stop reaches the frame. Taller stops reduce the chance of bottoming out but can make the ride firmer over large bumps.
Inspect bump stops during regular service. Look for cracks, crumbling rubber or loose bolts, and replace any stop that is damaged. Self-tapping bolts can strip the threads in a pocket, so run them in carefully and check that they are secure before driving.
