5X130 D23 Adjustable Wheel Spacers for Supra and ATV

We use high-strength forged 6061-T6 or 7075-T6 aluminum alloy, ensuring excellent durability, corrosion resistance, and structural integrity. These materials are far superior to cast alternatives.

All bolts and studs provided are 12.9 alloy steel, heat-treated for strength and coated to resist corrosion and fatigue. They are suitable for high-speed and heavy-load conditions.

A hub-centric spacer has a center bore that precisely matches the hub, so the vehicle's hub carries the weight - not the studs.This design minimizes vibrations and ensures safe, balanced driving. We strongly recommend hub-centric spacers for optimal performance.

Yes - when properly designed, manufactured, and installed, wheel spacers are safe. Poor-quality materials or incorrect installation can lead to vibration, uneven tire wear, or even wheel detachment. That's why we only offer precision-machined,tested products.

We do not recommend using one universal stud length for all spacer sizes. Different thicknesses require matching stud lengths to ensure correct thread engagement and mechanical strength. Using one size for all may compromise safety. However, we can supply extra studs to simplify your inventory or provide pre-packed kits for each spacer.
