ReadyLIFT 5.0" Tapered Rear Block Kit | 2017–2026 Ford F-250 Super Duty 4WD

ReadyLIFT 5.0" Tapered Rear Block Kit | 2017–2026 Ford F-250 Super Duty 4WD

Is This for You?
You're running a 2017–2026 Ford F-250 Super Duty 4WD with a 1-piece driveshaft and you need 5" of rear block height to restore rake for towing and hauling, or to level out a heavily lifted front end. You need OEM-quality fabricated steel construction with integrated bump stop landing pads — not lightweight extrusions that flex under load. The ReadyLIFT 66-2750 is a model-specific, OEM-style tapered rear block kit engineered for 1-piece driveshaft F-250 applications, backed by a Limited Lifetime Warranty.

The Result
Five inches of rear lift via two OEM-style fabricated steel tapered rear blocks with integrated bump stop landing pads. The tapered design corrects pinion angle on 1-piece driveshaft applications, maintaining proper driveline geometry at the new block height. Four new long e-coated U-bolts with nuts and washers are included for a complete, clean installation. These blocks pair perfectly with any ReadyLIFT leveling kit and serve as the ideal tow package upgrade for stock-height, leveled, or lifted F-250 Super Duty trucks.

Verified Fitment (OFAS Standard)
✅ Fits: 2017–2026 Ford F-250 Super Duty 4WD (1-piece driveshaft)
❌ Does NOT fit: 2019–2026 Ford F-350 Super Duty — this block is F-250 specific
❌ Does NOT fit: 2-piece driveshaft applications — see 66-2741 for 2-piece driveshaft F-250 applications
❌ Does NOT fit: Trucks equipped with aftermarket or factory add-on air spring/load leveling kits that attach to the bump stop tangs — use of air bag systems on this block will void all warranties and can cause block bump stop tang failure
❌ Note: Lift height will vary depending on what factory block your truck has from the factory

Wheel & Tire Fitment
No wheel or tire restrictions specific to this component. Rear block height affects overall vehicle rake and stance — verify your total lift height and tire clearance with your existing front lift configuration before ordering.

Installation & Engineering Notes
This is a bolt-on rear block kit requiring no cutting or welding. U-bolts must be torqued to OEM specification at ride height. A professional alignment check is recommended after installation to confirm ride height and driveline geometry. Do not use this block kit with aftermarket or factory add-on air spring/load leveling systems that attach to the bump stop tangs — doing so will void the warranty and risks structural failure of the bump stop tang. Lifting your vehicle raises its center of gravity; exercise appropriate caution when towing or hauling. All Advanced Driver Assistance Systems (ADAS) including Ford Co-Pilot360 and automatic headlight leveling should be verified after any suspension height change.

Engineering Question: Does your 2017–2026 F-250 Super Duty have a 1-piece or 2-piece driveshaft, and what is your current factory block height? Confirm your driveshaft configuration before ordering — this kit is engineered for 1-piece driveshaft applications only. For 2-piece driveshaft F-250 trucks, see ReadyLIFT 66-2741.
