dynofit F150 3 in Rear Lift Blocks Kit - Stable 3in Rear Lift

In this review the dynofit F150 3 in Rear Lift Blocks kit is judged on fit, durability and value for owners who want a straightforward rear lift for 2004-2020 F-150s. The kit's single biggest advantage is its clean, metal construction and longer U-bolts that replace weaker hardware, delivering a predictable rear lift without extensive fabrication. For owners who need to raise ride height for tire clearance or a level stance, this kit provides a simple mechanical solution with good corrosion protection and a design focused on stability.

Key Features

• Compatibility: Fits 2004-2020 F-150 2WD and 4WD with clear lift expectations per model year so buyers can choose the correct lift for their truck.
• Lift Amount: Provides a full 3in lift on 2WD trucks and calibrated additional lift on 4WD trucks depending on factory block height for predictable ride height changes.
• Stronger U-bolts: Includes longer 10.9 grade U-bolts with 9/16 thread pitch and thicker washers to match or exceed factory clamping strength for safety and longevity.
• High quality block: CNC machined steel blocks with a cross gusset plate locked design keep the leaf pack centered and improve rear stability under load.
• Durable finish: Black powder coating improves rust and corrosion resistance so the blocks maintain appearance and function over time.

Who It's For

This kit is best for owners of 2004-2020 Ford F-150s who want a straightforward rear lift without altering leaf springs, especially 2WD owners who need the full 3in increase or 4WD owners who want the modest additional lift noted for their model years. It also suits DIYers and backyard mechanics comfortable with basic suspension work and torqueing U-bolts to spec.

Customers who require electronic ride height adjustments, extensive suspension redesign, or who prefer polyurethane or adjustable aftermarket blocks should look elsewhere. This is a mechanical leveling/lift solution rather than an active suspension replacement.

Pros & Cons

Pros

• Solid build quality from CNC machined steel gives a metal alternative to plastic blocks and feels durable under load.
• Longer, high-grade U-bolts and thicker washers improve clamp strength and simplify installation without extra fabrication.
• Powder coated finish and cross gusset design increase corrosion resistance and stability over time.

Cons

• Lift amounts differ by year and 4WD models with existing blocks get a smaller net gain, so buyers must confirm fitment.

Frequently Asked Questions

Will this kit raise my F-150 3in?
On 2WD 2004-2020 F-150s it provides the full 3in; on 4WD models the net lift is reduced by the truck's factory block (1in net for 2004-2008 4WD, 1.5in net for 2009-2020 4WD).

Are the U-bolts strong enough for heavy loads?
Yes, the kit uses 10.9 grade U-bolts with thicker washers and longer length to match factory clamping strength and improve compression resistance.

Will sensors or alignment be affected?
Customers report no sensor issues after installation, but an alignment check is recommended after any suspension change to ensure proper handling and tire wear.
