This ReadyLIFT 5 inch rear block kit is for the 1999-2010 Ford F-250 and F-350 Super Duty with a two-piece driveshaft. The blocks are cast iron, based on OEM designs, with integrated bump stops, and the kit comes with longer E-coated U-bolts and hardware. It is not for trucks with a one-piece driveshaft.
Key features
- Cast iron blocks based on OEM designs, not lightweight extrusions
- Integrated OEM-style bump stops
- Longer U-bolts and hardware included
- Puts a slight rake in the truck for hauling or towing, and is meant to work with a ReadyLIFT leveling kit
What's included
- (2) 5 inch rear blocks

Fitment and compatibility
- Fits 1999-2010 Ford F-250 and F-350 Super Duty 2WD and 4WD with a two-piece driveshaft only
- Not compatible with aftermarket or factory add-on air spring or load leveling kits that attach to the bump stop tangs. Doing so voids all block warranties and can cause failure of the block bump stop tang

Installation
Allow about 1.8 hours, plus or minus 0.5, not counting alignment or wheel and tire assembly. ReadyLIFT lists it as a do-it-yourself install but recommends a certified mechanic. Your vehicle may need an alignment, the headlamp aim must be checked and adjusted, and driver-assist systems on some vehicles may need dealer tools and factory-trained technicians.
Modifying your suspension can change handling and rollover risk (SAE J2492). California Prop 65 notice: the manufacturer lists DEHP.
