Built for OBS Chevy and GMC 1500 owners who want aggressive ground clearance without sacrificing daily-drivability, this 6-inch lift kit combines improved suspension geometry with heavy-duty fabricated components. You'll gain up to 35-inch tire clearance while maintaining stock track width and factory alignment characteristics — meaning better handling on and off road.
