⚡ At a Glance
  • Build Quality: Heavy-duty steel construction with aluminium shims and robust U-bolts
  • Best for: Owners wanting modest lowering and improved handling on leaf-spring vehicles
  • Not ideal for: Vehicles without leaf springs or setups requiring non-leaf-spring lowering solutions

Universal lowering block kit designed to reduce ride height while improving cornering stability. Precision hardware and straightforward layout help ensure reliable, adjustable installation.


Long-lasting durability – thanks to high-strength steel construction

High-strength steel elements work alongside aluminium shims and sturdy U-bolts to resist corrosion and retain shape under repeated loads. Precision manufacturing of threads reduces loosening over time.

Durable materials and accurate threading keep mounting secure, cutting the need for early replacement. Suitable where repeated use and reliable clamping matter.

Improved handling – thanks to lowered centre of gravity

A deliberate drop in axle height lowers the vehicle centre of gravity, which reduces body roll and alters suspension geometry to produce a firmer response. The block stack maintains alignment while the axle sits lower.

More composed cornering and a steadier feel during manoeuvres, useful for drivers who prefer a firmer stance. Stability gains are most noticeable during turns and lane changes.

Straightforward installation – with precision-threaded bolts and nuts

U-bolts and nuts feature precise threading that eases alignment and clamps the shim stack securely. The compact kit layout keeps the number of parts low for faster on-vehicle assembly.

Quick to fit for competent DIYers or workshop technicians, saving time compared with more invasive suspension changes. Alignment adjustments are achievable without specialised fabrication.
