Zone Offroad Products has introduced 6-inch suspension lifts for '73-'87 Chevy/GMC 1/2- and 3/4-ton trucks and '73-'91 Chevy/GMC 1/2- and 3/4-ton SUVs.
The front suspension features five-leaf-pack springs with anti-friction pads and center leaf spacer plates between each leaf. Zone says this design significantly decreases leaf pack internal friction for a smooth and consistent spring rate. Also included is a 4-inch steering arm to correct the drag link angles; brake line relocation brackets; front and rear yellow zinc-plated U-bolts with high nuts and washers; and front and rear shocks. The rear of this system is lifted with a 4-inch lift block and add-a-leaf to achieve 5 to 6 inches of rear lift.
This kit allows fitment of up to 37x12.50 tires on 15x8 wheels with 3.5 inches of backspacing. Pricing starts at $599.95.
