Eibach S1-1-12-50-43-17 Wheel Bolt M12x1.5 43mm Length Taper Seat 17mm Hex

The Eibach S1-1-12-50-43-17 is a precision-engineered replacement wheel bolt designed specifically for use with Eibach Pro-Spacer wheel spacer systems. This high-quality fastener features M12 x 1.5 thread specification with a 43mm overall length, making it ideal for applications requiring extended-length wheel bolts when running wheel spacers.

Key Specifications:

• Thread Size: M12 x 1.5mm metric fine thread
• Overall Length: 43mm (approximately 1.69 inches)
• Hex Size: 17mm for standard lug wrench compatibility
• Seat Type: Taper seat (conical) for secure wheel-to-hub contact
• Finish: Silver zinc-plated for corrosion resistance
• Manufactured to OE quality standards

When installing wheel spacers, the original factory wheel bolts are often too short to provide adequate thread engagement. This extended-length bolt ensures proper and safe installation by compensating for the added spacer thickness. The taper seat design matches most European vehicle wheel configurations, providing centered wheel mounting and proper load distribution. Each bolt is precision-manufactured to ensure consistent torque specifications and reliable performance.

Note: Sold individually. Determine the number of bolts required based on your vehicle's bolt pattern (typically 4, 5, or 6 bolts per wheel). Always ensure proper torque specifications are followed during installation and re-torque after 50-100 miles of driving.
