Superlift 99-10 Ford F-250 SuperDuty 4in Block Kit w/ 3 7/8 AxleTube w/o Top Mounted Overload Leaf

This Superlift 4-inch rear block kit is what you get when you need to lift the back of your 1999-2004 Ford F-250 or F-350 Super Duty. Inside the box, you'll find two solid cast iron blocks, four U-bolts, and all the necessary nuts and washers to get them installed. This kit is specifically designed for trucks with a 3 7/8 inch axle tube and without the top-mounted overload leaf spring.

Superlift has been around since 1975, and they build their parts with truck owners in mind, whether you're on the road or heading off-road. These cast iron blocks are a straightforward way to add height to your rear suspension, and the included hardware means you've got most of what you need for the job. Just make sure your truck has the specific axle tube size and overload leaf configuration this kit is made for.
