The Quadratec® Difference
Starting at
Rock Krawler Suspensions 3.5” Flex Systems are designed for the JK owner looking for more out of their vehicle. These kits include the same industry leading products available in our Stock Mod kit. You will receive the same high quality triple rate coil springs, adjustable track bar, and rear track bar relocation/reinforcement bracket. Also included are a pair of front heavy duty adjustable lower control arms and extended brake lines. The adjustable lower control arms allow you to dial in your vehicles caster for a great improvement in handling and performance. 35” tires are recommended for OEM fender flares. 37” tires will fit when vehicle is equipped with flat/high clearance fender flares. You can either purchase shocks separately, or you can select one of Rock Krawler's proven RRD 2.0 Prodigy shock options.
