Ford 1988-97 F-250/350 Fabricated Blocks

PMF Ford 1988-97 F-250/350 Fabricated Blocks are built for customers who want a stronger, safer, and cleaner rear lift solution than stacked blocks. These heavy-duty fabricated blocks incorporate the U-bolts for an extremely solid and secure setup, helping prevent block shifting and reducing the risk of failure. Built for trucks with a 3-inch wide leaf, they are hand welded from 1/4-inch material to deliver exceptional strength and quality.

These blocks are offered in 1/2-inch increments so you can dial in your truck’s stance exactly how you want it. Multiple pin locations allow axle positioning adjustments when needed to better center the axle in the fender well, and PMF also offers optional bumpstop tabs, air bag tangs, and custom U-bolts to further tailor the setup to your application.
