Rock Krawler X Factor X2 PRO ELITE Long-Arm Upgrade For Jeep JK/JKU
The Rock Krawler X-Factor ELITE PRO Long-Arm Upgrade is specifically designed for Wrangler owners who want to push their vehicle to its limits with hard core rock crawling. This upgrade features an Independent 3 link design for maximum articulation and off-road performance. The lower control arms are our signature PB+J (Pure Beef and Jealousy) arms machined from 2” x 3” billet 7075 Aluminum. We have built the X-Factor X2 system to be the toughest 3-Link setup on the market. At the frame connections of the lower control arms, our "Adventure Series" maintenance free joint is used to cut down on the amount of grease points, and provide excellent vibration absorption and proper joint misalignment when off-road. The combination of long-arms and 3 link suspension geometry lets you dominate the trails. When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail! Thank you for considering Rock Krawler Suspension.

General Notes:
All lift heights based on Rubicon models for standard style build (i.e. front bumper and winch, rear bumper and full size spare).
If building with a spare delete we recommend dropping 1” in coil lift height for the rear.
If building an overland or heavily up-fitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
We recommend a new front driveshaft if you plan to off-road routinely. (Adam's Driveshaft Woods, J.E. Reel, etc.)
