Bring Your Rear Suspension Back Into Balance

If you’ve leveled or lifted the front of your 2017–2024 F-250 Super Duty and noticed the rear end sagging a little more than you’d like, the ReadyLift 66-2740 4" Rear Lift Block Kit is the simple fix that brings back the rake and balance your truck needs for serious towing or hauling. Whether you’re towing a camper, hauling materials, or just want your truck to sit right, this kit helps restore that factory-style stance without compromising strength or durability. The 4-inch tapered blocks are built from heavy-duty fabricated steel, giving you the kind of support you can count on under load. Integrated bump stop pads help preserve factory ride control, so you get a lift without losing drivability. And if you’re running a 1-piece driveshaft, this kit bolts right up with zero cutting or guesswork. It even comes with long, e-coated U-bolts and all the hardware you need for a smooth install. This kit is a favorite for truck owners who want their rig to look right and perform even better, especially when that trailer’s hooked up and the road ahead isn't flat.

Engineered To Work With Your Suspension Setup

The ReadyLift 66-2740 kit is precision-built for 2017–2024 Ford F-250 Super Duty 4WD trucks equipped with a 1-piece driveshaft and a single-rear-wheel axle. The tapered 4-inch blocks are designed to accommodate factory bump stop contact, helping maintain proper suspension geometry and shock control through the full travel of your rear axle. By lifting the rear end to match a leveled front, this kit prevents squat under load and promotes better load distribution across your suspension system. Each block is fabricated from high-strength steel and paired with four long U-bolts that are treated with a corrosion-resistant e-coat for maximum durability. The hardware package also includes all the necessary nuts and washers for a secure fit you won’t have to second guess. Installation is straightforward and fully bolt-on, making it a solid option whether you're upgrading your truck at home or handing it off to a shop. It's important to note this kit is not compatible with trucks using air spring or load-leveling systems mounted to the bump stop tangs, as those setups can interfere with block integrity and void the warranty.
