These new Zone Offroad leaf 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. These springs are designed to give 4" of lift for the front or pickup, Blazer, Jimmy, or Suburban. These Chevy/GMC leaf springs are designed maintain the factory ride, but can still hold up and handle your load of gear all at a fair price you have come to expect from Zone Offroad.
