Zone Offroad now has lifts kits for your 3/4 ton Chevy or GM truck going back to 1973 with this new 4" lift system. Many hours of development and testing have finally produced a capable leaf spring that we are proud to introduce to our lineup. These springs are a 5 leaf pack with anti-friction pads and center leaf spacer plates between each leaf. This design significantly decreases leaf pack internal friction for a smooth and consistent spring rate. This system comes complete with a 4 steering arm to yield the factory drag link angle. Zone Offroad also addresses the brake lines by providing front and rear brake line relocation brackets. Front and rear yellow zinc plated u-bolts with high nuts and washers are included to bolt the front springs and rear 4" lift blocks to the axles. If your truck came with a front sway bar, Zone Offroad has you covered with a unique shackle sway bar link design listed in the accessories that will fit lifts from 2-6. Choose Zone Offroad for an affordable yet high quality system for your 73-87 3/4 ton Chevy truck.
