About this kit

2.5-Inch M1 Leveling Kit with Track Bar, fitment-checked

This package goes past springs alone — two 2.5-inch front leaf springs, front and rear M1 monotube shock pairs, a tubular track bar rated for 2.5-3 inches of lift, and a universal U-bolt kit. It fits 1999–2004 Ford F-250, F-250 Super Duty, and F-350 Super Duty 4WD, and excludes V-8 gas engines, dually axles, and production dates before 3-1-1999.

Built as a 2.5-inch leveling kit for the 1999–2004 Ford F-250 and F-350 Super Duty 4WD, this version arrives with the geometry parts included: a tubular track bar rated for 2.5-3 inches of lift keeps the front axle centered at the new ride height, and a universal U-bolt kit comes along with the front leaf springs. M1 monotube shock pairs handle damping front and rear. Confirm the truck is not a dually, does not have a V-8 gas engine, and was built on or after 3-1-1999. Shipping weight is 181 lb.
