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 set above the main leaf. You will need to identify which you have before ordering.
- The kit comes with a single steering stabilizer in the kit, but you can upgrade to a dual system in the customize your kit section.
- If your vehicle is equipped with a carrier bearing, you will need to order 123402 in the options section.
- Do not install the 4" rear block kit on vehicles equipped with a factory 3-7/8" rear block. Only use rear spring option on these vehicles.
