Product Overview
More Information

We have a budget, deluxe and premium package available for all these models. The leaf springs used in these packages are made from top quality steel then tapered cut and refined using shotpeening technology to provide excellent ride and superior strength. Teflon friction pads are employed between springs to reduce inter-leaf wear. When the spring is compressed, the pads allow the leafs to slide against each other. This helps make the ride more smooth and improves suspension travel. The springs also come with degree shims attached which reduces drive line angle, thus helping to prevent drive line vibration. In order to keep the steering geometry at the proper angle, a drop pitman arm is used in the taller kits. This reduces 'bump steer' and allows the vehicle to maintain a full turning radius.

Premium Kit Includes:
- Spring Eye Bolt Kit
- Pro Comp Steering Stabilizer w/ Boot
- Front and Rear Brake Lines
- Pitman Arm
- Front and Rear Leaf Springs
- U-Bolts

Important NotesIf vehicle has front or rear 'tulip' style drive shaft (rubber boots on both ends of shaft) must switch to U-joint style drive shaft. 74-75 models must have 131 inch wheel base and 72000 GVWR or more for rear springs to fit.
