6" 1999-2006 GMC Sierra 1500 (w/gas engine) 4WD Lift Kit by Zone

Ready for all your friends to be jealous? This Zone GMC kit is the ultimate in style and performance. Whether you are just driving to work or playing on the trail, this system was designed to perform. The main crossmembers were designed to match the factory geometry with the new Zone CNC machined steering knuckles creating a true factory quality driving experience. Match this geometry with the heavy duty differential skid plate that locks the main crossemembers together and the compression struts that tie back to the frame and you have a system ready for some serious abuse! 100% Made in the USA!

Features:
- CNC Machined ductile iron knuckles.
- Diffential skid plate included to protect the front differential and lock the crossmembers together.
- Compression struts included to support the main crossmembers for serious off roading.
- 1/4" thick steel used to make indestructable crossmembers.
- 3-point differential mounting system correctly positions the differential so the factory driveshaft can be used.
