ReadyLIFT 1.0-Inch Rear Block Kit | OEM-Style Cast Iron Construction | Integrated Bump Stop Landings + Cast-In Center Pins | E-Coated U-Bolts Included | 2019–2023 Ford Ranger 4WD | SKU: 66-2910

Verified Fitment

Does NOT fit:

• Ford Ranger 2WD / RWD — 4WD only; 2WD Ranger rear suspension geometry is different
• 2024 and newer Ford Ranger — the 2024 Ranger represents a new generation platform (P703) with different rear suspension mounting geometry; this kit is confirmed for the first-generation 2019–2023 Ranger (P375 platform) only; confirm platform before ordering 2024+ applications
• 2018 and earlier Ford Ranger — previous-generation Ranger (pre-2019 return) uses different rear suspension
• Ford F-150 or other full-size trucks — this is a midsize Ranger-specific block

Generation identification: The 2019–2023 Ranger is the first-generation return-to-market platform (P375). The 2024 Ranger is a completely redesigned second-generation truck (P703) with different dimensions and rear axle geometry. If your Ranger is a 2024 or newer model year, text (469) 407-7538 before ordering to confirm compatibility.

Component Specifications

Why cast-in center pins: The center pin on a leaf spring rear block locates the block relative to the spring perch and prevents the block from migrating laterally under braking, cornering, or load cycling. Cast-in center pins — integrated into the block during manufacture — provide more positive location than separate pressed-in pins. This is the same design philosophy as OEM Ford rear blocks.

Why not stacking: ReadyLIFT explicitly notes this kit eliminates the need to "illegally stack rear blocks." Federal Motor Vehicle Safety Standards prohibit stacking lift blocks — multiple separate blocks can migrate and separate under load, creating an uncontrolled suspension condition. A single purpose-built 1" block achieves the height legally and safely.

Field 4 — What Is and Is NOT Included

Critical Compatibility

4WD only — 2WD Ranger does not apply. The 4WD Ranger's rear axle uses different U-bolt sizing and spring perch geometry than the 2WD configuration. This block kit is confirmed for the 4WD rear axle only.

2024+ Ranger generation change. The 2024 Ranger redesign changed multiple rear suspension dimensions. No confirmed fitment data exists for the 66-2910 on the 2024+ platform. The conservative and correct answer is: confirmed 2019–2023; 2024+ requires verification. Do not assume the second-generation Ranger is compatible without confirming.

No block stacking. If 2 or more inches of rear lift are needed, a purpose-built 2" block is the correct approach — not two 1" blocks stacked. Using this block alongside any other block violates federal motor vehicle safety standards and will void the ReadyLIFT warranty.

Installation Notes

Skill level: Beginner to intermediate. Estimated installation time 1.8 hours ±0.5 hours (excluding alignment and wheel/tire assembly). Bolt-on — no cutting or welding required. ReadyLIFT recommends installation by a certified mechanic.

Tools required: Floor jack and rated stands, basic socket set, torque wrench.

Installation sequence:

1. Safely lift and support the vehicle with the rear axle at full droop.
2. Remove the factory U-bolts and lower the rear axle.
3. Remove factory rear block (if present).
4. Position the ReadyLIFT 1-inch block between the axle perch and the leaf spring — align the cast-in center pin with the locating hole in the spring perch.
5. Install the e-coated U-bolts and thread the included nuts.
6. Lower the axle to ride height.
7. Torque U-bolts to OEM specification at ride height — do not torque with the axle at full droop.

Post-installation mandatory steps:

1. Re-torque U-bolts after 500 miles — blocks settle slightly during initial load cycling.
2. Alignment verification — recommended after rear height change.
3. Headlamp aim adjustment — required per ReadyLIFT installation advisory.
4. ADAS verification — check Ford Co-Pilot360 and all associated safety systems for proper function.

Common Questions

Does this fit my 2024 Ranger?
The 66-2910 is confirmed for the first-generation 2019–2023 Ranger (P375 platform). The 2024 Ranger is a completely new-generation platform with different rear suspension geometry. Text (469) 407-7538 before ordering for a 2024 Ranger — we'll confirm current fitment data before you purchase.

Does this fit my 2WD Ranger?
No — the 66-2910 is confirmed for 4WD applications only. The 2WD Ranger's rear suspension configuration is different. If you have a 2WD Ranger, text (469) 407-7538 and we'll identify the correct rear lift option for your application.

Can I stack two of these to get 2 inches of rear lift?
No — block stacking is prohibited by federal motor vehicle safety standards and will void the ReadyLIFT warranty. If 2 inches of rear lift is needed, a purpose-built 2-inch block is the correct solution. Text (469) 407-7538 for available Ranger 2-inch rear block options.

Why is there a center pin in the block?
The cast-in center pin locates the block on the spring perch and prevents it from shifting laterally under braking, cornering, or load. Cast-in pins provide more positive location than separate pressed-in pins. The corresponding locating hole in your factory spring perch accepts the center pin during installation.

Do I need to do anything after installation besides check the U-bolt torque?
Yes — three additional steps: headlamp aim adjustment (the height change alters headlamp projection angles), ADAS verification (Ford Co-Pilot360 and similar systems should be checked for proper function), and an alignment verification is recommended. These are standard post-installation procedures for any suspension height change.

The Obsidian Take

The 66-2910 is the correct, legal rear lift solution for 2019–2023 Ford Ranger 4WD owners who've installed a front leveling kit and need the rear to match — or who simply want to restore towing rake to a truck that squats under load.

The design philosophy is identical to every other ReadyLIFT rear block kit in this catalog: OEM-style construction, integrated bump stop landings, cast-in center pins, included U-bolts, no stacking. The 1-inch height is the right answer for Ranger owners pairing this with a 2-inch front leveling kit — it produces a slight nose-up rake that levels out under normal towing and hauling loads while maintaining a visually purposeful stance.

At 1.8 hours of installation time, this is one of the fastest suspension upgrades in the OFAS catalog. The bolt-on nature of the installation — no cutting, no welding, no specialty tools beyond a floor jack and torque wrench — makes it accessible to any intermediate DIY builder or any shop.

The 2024+ Ranger platform change is the one note worth carrying into any conversation about this kit. The new-gen Ranger is a legitimately different truck from the 2019–2023. Don't assume the block transfers — verify first.

This SKU is for: 2019–2023 Ford Ranger 4WD owners who want 1 inch of rear lift to restore towing rake, pair with an existing leveling kit, or achieve a level lifted stance all the way around — using a purpose-built single-block solution with integrated bump stop landings and cast-in center pins backed by ReadyLIFT's Limited Lifetime Warranty.

This SKU is NOT for: Ford Ranger 2WD owners, 2024 and newer Ranger owners (new platform — confirm before ordering), 2018 and earlier Ranger owners, anyone needing more than 1 inch of rear lift (do not stack — order the correct height block), or anyone running a truck outside the confirmed 2019–2023 first-generation platform.
