Fitment and compatibility
- Fits 1999-2010 Ford F-250 and F-350 Super Duty with a one-piece driveshaft; two-piece driveshaft trucks are covered by separate listings
- Does not fit F350 dually applications, because the U-bolts will not fit
- Not designed for aftermarket or factory add-on air spring or load leveling kits that attach to the bump stop tangs. Doing so voids block warranties and can cause tang failure
