Rock Krawler Suspension
LJ 5.5 Rock Runner (Stage 1)
- 2004 to 2006 LJ Wrangler Unlimited and Rubicon Unlimited
The LJ 5.5" Rock Runner System is perfect for those looking to get the most out of your Wrangler. The wheel base is stretched to 99" making it great for just about all off-road conditions as well as street use. The high clearance lower control arms improve cross over angles and off-road ability. The sport tuned 14" travel front and 13" travel rear 2 5/8 RRD Racing Coil Overs provide great on road ride and off-road performance. Like all of our RRD products, they are full adjustable and tunable. The rear coil overs are frenched into the frame ahead of the axle enhancing the off-road ability even further, much like an off-road race vehicle! Please make sure to review the requirements for the system and proper fitment before purchasing in the notes below.
