Fitment: 2011-2019 F250 Super Duty ONLY. F350s come with a 4" block stock.
Fits 2-Piece Driveshafts Only: This 4" Rear Block Kit is designed to fit stock 2-piece driveshafts ONLY.
Towing Information: Because this kit was designed with F250 trucks that are used for towing, a slight front-end rake will be added to your Super Duty. The look gets evened-out when you're actually towing, however, for proper weight distribution.
