ECS Tuning Extended Wheel Bolts for Precise Fitment

Enhance your vehicle's wheel fitment precision with ECS Tuning's extended wheel bolts, designed individually or paired with spacers to ensure accurate compatibility. These bolts are engineered to meet the rigorous ISO 898 class 10.9 standards, ensuring exceptional mechanical and physical properties, including stringent material, hardening, tempering, and proof load strength criteria. Our fasteners undergo lab testing to guarantee compliance with class 10.9 requirements.

Bolt Specifications:
  • Diameter: 12mm
  • Thread Pitch: 1.5mm
  • Length: 45mm

*For proper fitment when using wheel spacers, add the spacer size to the length of the OE wheel bolt (e.g., 27mm Length OE Wheel Bolt + 15mm Wheel Spacer = Requires a 42mm Length Bolt)
