Rough Country's Lift Kit is a true four-link setup with new, longer travel arms. The lift kit maintains a strong emphasis on offroad performance, but aims to keep suspension geometry as close to the factory angles as possible. This highly capable setup transforms your rig into a rock crawling beast, while delivering the smooth highway ride quality of a daily driver. 

Features and Benefits: 
- Exceptional On- and Off-Road Ride Quality
- No Welding Required
- True Four-Link Setup with New, Longer Travel Arms
- Prevents Binding and Rear-Steer
- Front Adjustable Track Bar Made of Forged Solid Steel
- Includes N3 Shock Absorbers
- Coil Correction Plates  
- Superior Axle Flex with Optimized Pinion Angles  

Rough Country’s custom-engineered dual-rate coils provide two distinct levels of compression so you can overcome any obstacle with ease. Coil correction plates are included to correct the rear coil spring angle by 10 degrees, allowing them to function more efficiently. A full set of Nitrogen-charged N3 shocks further promote comfortable ride quality while delivering the maximum possible travel. 

You'll also receive a full set of front and rear upper and lower adjustable control arms. These X-Flex control arms give you the ability to adjust the wheelbase and pinion angle. The control arms are constructed of durable heavy-wall DOM tubing for long-lasting flex and performance. The corresponding brackets are made of a 1/4-inch thick high tensile strength plate steel. Each control arm uses Rough Country’s adjustable flex joints with Clevite OEM-style rubber bushings. The fully rebuildable flex joints feature a massive 2.5-inch diameter body and 1.25-inch thread.  

To ease the installation process, Rough Country includes extended stainless steel brake lines and coil correction plates. The kit is easier to install than other long arm kits with no welding and no removal of the factory crossmember required. 

Additional Notes: 
- Does NOT fit 2-door models.
- An upgraded front and rear driveshaft is HIGHLY recommended.
