Rock Krawler's 3 Inch X Factor System is, in Rock Krawler's words, an amazing starting point. It is a complete bolt-in kit that you can reverse. You get RRD 2.625 inch remote reservoir coilovers on all four corners with adjustable lift from 2 to 3 inches, fabricated front upper A arms, adjustable rear control arms and a rear track bar with a raised bracket. It is built for 35 to 37 inch tires on factory fender flares, and for owners who plan to add more Rock Krawler parts later.

Pick your package
The arms, coilovers and track bar are the same in both stages. Package is about the adjusters.
- Stage 1: RRD 2.625 inch remote reservoir coilovers at all four corners, with the arms and hardware listed above.
- Stage 2: Everything in Stage 1, with Fast CD adjusters on the coilovers. The adjusters let you dial in on-road and off-road damping to your own taste.
