BDS1303FS | BDS Suspension 6" Lift Kit For Ford F-250 / F-350 Super Duty 4WD | 1999-2004 | Front U Bolt Square, Rear Block Kit With Factory Overload, Fox 2.0 Performance Series

• 36 x 12.5 with 16 x 10 and 4 in. Backspace

Front U-Bolt Type

This vehicle was manufactured with either square front U-Bolts or radiused front U-bolts. Typically, 1999-2000 are square and 2001-2004 are radiused, but that is not always the case. The radiused U-bolts aren't square or round, but rather have a gentle radius that matches a cast factory upper U-bolt plate on top of the factory spring. Vehicles manufactured prior to 2-28-99 require yet another different box kit due to a change in the factory track bar. Please make the appropriate selection for your particular vehicle.

IMPORTANT NOTES

1. These truck were manufactured with two different style front u-bolts. You will need to know if your front leaf spring u-bolts are square or are half way between round and square with a gentle radius around the OE cast u-bolt plate before ordering.
2. Vehicles produced before 3/1/99 require a different box kit. You must check the production date on the door prior to ordering.
3. The Superduty came from the factory with a 2", 3", or 4" rear block. If you wish to truly level your vehicle it may be necessary to change the rear OE block.
4. Will not fit dually applications.
5. If your vehicle is equipped with a carrier bearing, you will want the 123402 drop kit in the options section.
6. The front driveshaft will need to be lengthened and/or clearance ground depending on how the vehicle is equipped.
