High-Performance H&R Wheel Stud Conversion

Transitioning from wheel bolts to a stud conversion kit is one of the best upgrades for track enthusiasts and frequent wheel changers. H&R 12x1.5 50mm Wheel Studs offer the durability and convenience needed for rapid pit stops and consistent wheel mounting. With a 14.20mm knurl diameter, these studs are designed for a precise press-fit into your hub, providing a stable foundation for your wheels.

Key Features and Specs

  • Thread Pitch: 12x1.5
  • Length: 50mm
  • Knurl Diameter: 14.20mm
  • Material: High-strength alloy steel
  • Application: Stud conversion
  • Benefits: Faster wheel changes, improved thread protection

Wheel studs simplify the process of aligning your wheels, especially when using heavy aftermarket rims or wheel spacers. By eliminating the struggle of holding a wheel in place while threading a bolt, these studs significantly reduce the risk of cross-threading and hub damage. H&R manufactures these studs using premium materials to ensure they can withstand the high-torque demands of aggressive driving. The 50mm length provides versatility for various wheel offsets and spacer combinations. When you switch to a stud-based system, you gain the ability to use open-ended lug nuts, allowing for quick visual inspections of thread engagement. Ensure your vehicle is track-ready with high-quality components designed for longevity and performance.
