ZONE 4" RADIUS ARM LIFT SYSTEM WITH FRONT COILS AND REAR BLOCKS WITH NITRO SHOCKS | 11-16 SUPERDUTY DIESEL WITH OVERLOAD SPRINGS

• Full length replacement coil springs add additional ride height while maintaining ride quality.
• Heavy-duty track bar re-centers front axle, adds strength and limits lateral movement.
• High-strength, 1/4" steel construction corrects caster, improves tire clearance, and maximizes ground clearance.
• Rear lift block and longer U-bolts for easy installation and level stance.

Important Note: Although extremely rare, front and/or rear drive-line vibration may occur and require drive-line modification. This kit is not designed for dually models. This lift will require replacing your truck's factory rear block to achieve a level stance; total height gained will vary depending on the size of the factory block. Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid / eliminate driveshaft vibration.
