Description
High-Quality Suspension Components
Sinister Diesel has built quite a name for themselves in the diesel industry, and everything about their 2.5″ Leveling Kit reflects their well-known reputation for quality. Whether you’re looking to clear 35″ off-road tires or you just want a slightly taller ride, the 2.5″ Leveling Kit by Sinister Diesel is more than qualified for the job. Unlike an add-a-leaf leveling kit, this 2.5″ Leveling Kit achieves most of the lift from the thickness of the pack, rather than re-arching the OE leaf pack. This means that ride quality will be maintained while properly leveling your vehicle.
No Modifications Required for Installation
All it takes to install Sinister Diesel’s 2.5″ Leveling Kit and get that wicked stance you’re looking for is a couple hours of your time and basic tools. This leveling kit includes two leaf spring packs as well as longer u-bolts and all required hardware for installation.
Fitment: 1999.5-2004 Super Duty 6.0/7.3L 4WD
Wheel & Tire Fitment: Most trucks will run 35″ tires with this kit, although there will need to be some slight trimming to the lower bumper valance.
Curved U-Bolts Only: this kit will only fit 1999.5 Super Duty models that have curved U-bolts for their front springs. It will not fit early 1999 models with square U-bolts.
