Zone Offroad has spent many hours developing & testing a capable leaf springs for the straight axle Chevy, GMC vehicles. 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 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.
