Product Details

Climb up and stand out from the crowd with this 4" Lift Kit that will have you clearing 35" tires. You'll definitely make a statement with this complete with leaf spring & block lift for your 4WD 1999 Ford F-250 / F-350.

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.
