X Factor X2 Pro Elite w/ 6 Inch Stretch Long-Arm Upgrade For Jeep Wrangler JK Rock Krawler

Rock Krawler X Factor X2 Pro Elite w/6 Stretch Long-Arm Upgrade For Jeep JK/JKU

The Rock Krawler Suspension 4.5 X - Factor X2 6 Stretch Pro Elite Long-Arm System is the ultimate in compromise between daily driver/hard core off-roader. Pro derives from having a set of PB&J (Pure beef and jealousy) Billet aluminum lower control arms.

These arms are custom machined in-house, built using a solid square stock bar of Billet aluminum and engineered to quite literally, handle any abuse you can throw at them. The X - Factor X2 systems combine the benefits of a independent 3 link front and rear suspension system.

This is where conventional on-road handling meets bad ass off-road ability. Our proprietary design utilizes a double adjustable front and rear upper control arm that upsizes the factory hardware to 14mm, 2 3/8 mounting width and 1 Pro Krawler joints at one end.

The rear system uses our tried and true independent 3 link conversion with X2 rear suspension geometry with enhanced rear instant center (s) and rear roll center (s). We provide the necessary brackets and control arms needed to achieve a 6 rear suspension stretch in order to give an enhanced wheelbase.

This helps with greater off-road capability and better on-road handling characteristics in a 2-door wrangler. The new high clearance axle mounts provide 3.5 inch of ground clearance under the rear axle as compared to stock.

The rear upper shock relocation brackets ensure you do not lose any shock or suspension travel.
