The Aluminum Backing Washer 14mm from ALLSTAR PERFORMANCE is a precision fastening component designed for motorsports and high-performance automotive assembly work. This backing washer serves as a critical load-distribution element under bolt heads and fastener connections, preventing material deformation and maintaining structural integrity in engine builds, suspension modifications, and chassis work.
Machined from lightweight aluminum alloy, the 14mm backing washer offers superior corrosion resistance compared to steel alternatives while reducing overall component weight—a critical consideration in performance builds where every ounce matters. The aluminum construction ensures ease of installation and future disassembly without risk of damage to bolt threads or mounting surfaces.
This backing washer is ideal for mechanics and fabricators working on aluminum engine blocks, thin-wall castings, composite panels, and custom chassis modifications where standard steel washers would cause material deformation. The 14mm bore diameter is specifically designed for compatibility with M14 bolts, ensuring optimal performance in various automotive applications.
