Built for Chevy and GMC 1500 owners who want aggressive stance without sacrificing daily usability — this 3.5" lifted knuckle kit delivers the ideal balance of ground clearance, bold looks, and on-road manners. The precision-engineered knuckle design repositions your CV axles for better clearance and longer boot life, while a front-to-rear level stance eliminates factory rake. Accommodates 33"–35" tires.

What's included
- 3.5" Stamped Steel & Aluminum LCA Knuckles — engineered to raise the CV axle position and reduce boot stress while maintaining compatibility with factory suspension geometry.
