Racewill Leaf Spring Lowering Block Kits bring a simple mechanical change for owners seeking a lower rear stance on leaf-sprung vehicles. Lowering by a fixed amount can improve the vehicle's look and stance while keeping load-bearing capacity intact. Will the 2-inch drop and supplied hardware match your needs and workshop capabilities?
⚡ At a Glance
- • Lowering Effect: Replacing the spacer between leaf spring and frame can reduce rear ride height by 2 inches
- • Best for: Owners who want a lower rear stance while retaining standard leaf-spring geometry
- • Not ideal for: Vehicles requiring specific manufacturer‑approved suspension settings or electronic ride-height systems
Extruded aluminium blocks sit between the leaf spring and frame to alter spring perch height, producing a controlled rear drop. Galvanised steel U-bolts and full hardware are included for a complete rear axle clamp-up.
Lower Rear Ride Height – thanks to a 2-inch lowering block
A direct-replacement block fits between the leaf spring and axle saddle, increasing the distance between spring perch and axle centre. The 2-inch stack changes the static ride height without altering spring rate or adding coil components.
A predictable 2-inch reduction in rear height achieves a lower stance while keeping original spring behaviour intact, useful for improved aesthetics or to match front/rear ride heights.
Durable Load Support – with extruded aluminium blocks
Blocks are extruded from high‑strength aluminium to deliver consistent section thickness and structural integrity under load. The metal resists deformation while offering lighter weight than comparable steel blocks.
Strong, dimensionally stable blocks support suspension loads reliably, which helps preserve alignment and handling after installation.
Corrosion Resistance for Wet Climates – with galvanised U-bolts
U-bolts are made from premium steel with a galvanised anti‑rust layer, specified at 3 inches width by 10 inches length. The finish reduces surface corrosion in humid or coastal environments.
Galvanised fasteners increase service life where salt and moisture are present, reducing the need for frequent replacement of suspension clamp hardware.
✨ The 4 Key Reasons for Racewill Leaf Spring Lowering Block Kits
- Extruded aluminium blocks – Consistent strength with reduced weight compared to steel
- Galvanised U-bolts (3" x 10") – Better corrosion resistance for humid or coastal use
- Complete hardware pack – Includes blocks, U-bolts, lock washers and nuts for full installation
- Multiple height options – Choice of eight heights allows tailored stance and styling

❓ Frequently Asked Questions
Q: Will these blocks actually lower the rear by 2 inches?
A: Yes, replacing the spacer between the leaf spring and the frame can reduce the rear suspension height by 2 inches when the matching block size is used.
Q: What materials are used for the blocks and U-bolts?
A: Blocks are made from extruded aluminium for strength and lightness, while U-bolts are premium steel with a galvanised anti‑rust layer for corrosion resistance.
Q: Does the kit include everything needed to fit the blocks?
A: Yes, the kit is supplied with two blocks, four U-bolts, eight lock washers and eight lock nuts, and the listing advises fitting under professional guidance.
🏆 Our Verdict
Suitable for owners who want a straightforward way to lower the rear of a leaf‑spring vehicle for styling or ride‑height matching, without changing spring rates. Sturdy extruded aluminium blocks paired with galvanised U‑bolts and a full hardware pack make the kit a practical, corrosion‑aware upgrade. The parts and complete hardware suggest good long‑term value for a mechanic‑fitted suspension change.
