About Allstar Performance

Allstar Performance is America's leading circle-track racing parts manufacturer. From aluminum panels and chassis components to brake hardware, steering boxes, and oval-track shock packages — every Allstar product is born from sprint car and modified racing experience.

Reinforce Your Fasteners with Allstar Performance 1/8in Aluminum Backup Washers

In high-performance automotive and racing environments, every component plays a crucial role in maintaining structural integrity. The Allstar Performance 1/8in Aluminum Backup Washers 500-Pack are essential for reinforcing riveted or bolted connections, especially when working with thin, soft, or composite materials. These precision-stamped washers significantly increase the bearing surface area, effectively distributing the load and preventing fasteners from pulling through or deforming the material. Crafted from lightweight aluminum, they offer excellent corrosion resistance without adding unnecessary weight to your build.

Optimal Support and Load Distribution

Designed to complement 1/8-inch fasteners, these backup washers feature a 0.125-inch inner diameter (ID) and a 0.375-inch outer diameter (OD), providing an ideal balance of support and compactness. The 0.06-inch thickness ensures robust reinforcement without creating excessive bulk. By spreading the clamping force over a larger area, these washers are indispensable for securing components to fiberglass, carbon fiber, plastics, or thin sheet metal, where concentrated pressure could lead to damage or premature failure. This 500-pack ensures you have an ample supply for extensive projects.

  • Precision Aluminum Construction: Lightweight, corrosion-resistant, and durable.
  • Ideal for 1/8in Fasteners: Perfectly sized for common automotive rivets and bolts.
  • Enhanced Load Distribution: Prevents pull-through and material deformation.
  • Optimal Dimensions: 0.125" ID, 0.375" OD, 0.06" thickness for versatile use.
  • Natural Finish: Provides a clean, professional appearance.

Essential for Durable Automotive Assemblies

Whether you're building a race car, restoring a classic, or undertaking custom fabrication, Allstar Performance backup washers are a fundamental component for ensuring the longevity and reliability of your assemblies. They are particularly vital in areas subjected to vibration or stress, where a standard fastener alone might eventually loosen or cause material fatigue. Invest in the peace of mind that comes with superior fastening support. Equip your workshop with these high-quality aluminum backup washers from GGCRACING for professional-grade results.
