LVOUP 1" Leaf Spring Lowering Block Kit – Billet Aluminium & Steel, 9/16" Centering Pin, Black (Pair)

LVOUP 1 Inch Universal Billet Aluminum Leaf Spring Lowering Block Kit is a durable steel-and-aluminum lowering block set that drops rear leaf-spring suspension by 1" for improved stance and fitment.

This 1" universal lowering block kit from LVOUP is engineered to provide a controlled, consistent drop for vehicles with leaf-spring rear suspension. Constructed from a combination of steel and billet aluminum, the pair of blocks includes an upgraded 9/16" centering pin for secure alignment. The kit ships in black and is sold as two lowering blocks—one for each side of the rear axle. Professional installation is recommended to ensure proper fitment and safety.

How does this 1" lowering block change my vehicle's ride and stance?

Dropping the rear by one inch reduces rear rake and brings wheel fitment closer to the wheel arch, creating a more balanced, level appearance. The block itself sits between the axle and leaf spring, changing the mounting offset without altering spring rate. Because it’s a modest drop, it preserves most OEM suspension geometry while improving aesthetics and compatibility with larger wheels or tires.

• One-inch drop per block for subtle stance correction
• Maintains original leaf spring spring rate and axle behavior
• Works with stock and many aftermarket wheel/tire setups

What materials and design features ensure strength and alignment?

The LVOUP lowering blocks combine heavy-gauge steel with billet aluminum to balance load-bearing strength and corrosion resistance. Each block includes a 9/16" centering pin to lock the block in position and prevent lateral movement under load. The black finish helps protect the metal from road debris and moisture for longer service life.

• Steel body for structural support and durability
• Billet aluminum components for precision and corrosion resistance
• 9/16" centering pin to maintain alignment under stress
• Protective black finish for added longevity

How easy is installation and what should I prepare?

Installation is straightforward for experienced mechanics: the blocks bolt between the axle and the leaf spring perch using existing hardware in most setups. Because vehicles differ, confirm fitment before purchase and follow vehicle-specific torque specs during assembly. A professional install is recommended to ensure safety and proper axle alignment.

• Uses existing axle and spring mounting points on most vehicles
• Verify compatibility with your vehicle before ordering
• Recommended to torque fasteners to manufacturer specifications
• Professional installation minimizes alignment and safety risks

Will these blocks fit my truck or SUV model?

These lowering blocks are sold as a universal 1" size, but fitment depends on the specific axle perch and U-bolt clearance of your vehicle. Check measurements against your vehicle’s spring perch and axle seat dimensions, and review clearance for U-bolts and brake lines. When in doubt, compare the block dimensions and pin size to your current hardware or consult a mechanic.

• Universal 1" sizing—compatible with many leaf-spring rear suspensions
• Confirm axle perch spacing and U-bolt length before purchase
• 9/16" centering pin must match or adapt to existing alignment hole

Who is this for: The LVOUP 1" Universal Billet Aluminum Leaf Spring Lowering Block Kit is aimed at truck and SUV owners seeking a modest rear drop for improved appearance or wheel/tire fitment, plus hobbyists and installers who prefer a robust steel-and-aluminum solution with a precise centering pin. It’s ideal for those who want a reliable, reversible ride-height adjustment without replacing springs. If you’re unsure about compatibility or installation, consult a professional installer or your vehicle’s service manual before purchasing.
