Racewill 3-inch Leaf Spring Lowering Block Kit — 3" Rear Drop, Extruded Aluminum & Hardware

Racewill 3-inch universal leaf spring lowering block kit drops the rear suspension up to 3 inches using sturdy extruded aluminum blocks and complete installation hardware.

This kit is designed for trucks and SUVs with leaf spring rear suspensions where a modest, even lowering is desired. The package includes two precisely machined aluminum blocks, four galvanized U-bolts, lock washers and nuts sized to fit the blocks, plus clear installation guidance. Built for durability and corrosion resistance, the components are intended to provide a clean, factory-like fit while reducing ride height and improving stance.

How does this lowering block kit reduce ride height?

The lowering block replaces the standard spacer between the axle and the leaf spring perch to move the spring mounting point upward relative to the axle, creating a 3-inch drop in rear ride height. Installation repositions the spring center over the axle using the supplied U-bolts and fasteners, maintaining secure attachment and alignment.

• 3-inch drop per kit when installed per vehicle specifications
• Two extruded aluminum blocks for consistent, even lowering
• Galvanized steel U-bolts sized 3" x 10" for secure clamping
• All necessary lock washers and nuts included

What materials and corrosion protection are used?

Racewill uses extruded aluminum for the blocks to achieve high strength with reduced weight, resisting deformation under load. The U-bolts are premium steel with a galvanized finish to protect against rust and corrosion in wet or humid conditions.

• Extruded aluminum blocks for strength and consistent dimensions
• Galvanized anti-rust layer on U-bolts for extended service life
• Durable lock washers and nuts sized to prevent loosening under vibration

Will this kit fit my vehicle and how do I choose the right height option?

The Racewill lowering block kits are universal for many leaf-sprung axles but vehicle-specific fitment depends on axle width, spring perch style and brake line clearance. Racewill offers multiple height options across the product line; this particular kit provides a 3-inch lowering block, and other heights are available if you need a different drop for clearance or stance.

• Compatible with most standard leaf spring rear axles; confirm perch dimensions first
• Measure axle-to-frame and brake/drive shaft clearances before selecting height
• Consult a professional installer or Racewill fitment guide for exact match

What comes in the box and what should a professional installer know?

The kit ships complete with two machined blocks, four galvanized U-bolts (3" x 10"), eight lock washers and eight lock nuts so you have everything to secure the spring to the axle. Proper torque sequencing and rechecking fasteners after initial road use are important; professional installation ensures correct alignment, safe torque values and preserves suspension geometry.

• Included: 2 blocks, 4 U-bolts, 8 lock washers, 8 lock nuts
• Recommended: installation by experienced technician with proper lifting equipment
• Post-install: torque check and road test to confirm secure fit and alignment

Who is this for? The Racewill 3" Lowering Block Kit is aimed at truck and SUV owners who want a modest rear drop for improved stance or lowered load height while preserving leaf spring reliability. Choose this kit if your vehicle uses a conventional leaf-spring axle and you prefer a durable, corrosion-resistant solution supplied with complete hardware. If you need a different drop or have uncommon perch dimensions, verify fitment with Racewill or a professional installer before purchasing.
