Important Notes

These trucks were manufactured with and without top-mounted overload springs on the rear leaf springs. A top-mounted overload is an extra leaf separate from the pack that sits above the main leaf. You will need to identify which configuration your vehicle has before ordering. If your vehicle is equipped with a carrier bearing, you will need to order part #123402 in the options section. Do not install the 4-inch rear block kit on vehicles equipped with a factory 3-7/8-inch rear block. Only use the rear spring option on these vehicles.
