Important Notes

The 1/2-ton commonly came with a factory 52-inch eye-to-eye rear leaf spring. However, some were produced with a 56-inch rear spring. If ordering rear leaf springs, be sure to measure your factory rear spring before ordering. If equipped with a factory front sway bar, order the front sway bar shackle link kit listed in the accessories section. Some vehicles came with factory front dual shocks. If you wish to replace the factory duals, you must order the additional two auxiliary shocks in the options. #001408 comes with OE style rubber bushings installed. Exhaust modification may be required to clear the front driveshaft.
