Important Notes
- Removal of the factory block is required.
- Installation of the rear block kit will result in a "pre-runner" look with the rear of the vehicle 2" lower than the front. To get a level stance you must upgrade to the rear leaf spring option.
- 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.
- If your vehicle is equipped with a carrier bearing, you will need to order 123402 in the options section.
- Although extremely rare, front driveline vibration may occur.
- Front exhaust modification may be required to clear the front driveshaft on gas models.
- U-bolts will not fit dually models.
- Dropped pitman arm will not fit 10 lug wide track F350 models.
