Alum Washer for 2.25 Poly Bushings

The aluminum washer for 2.25 poly bushings is a precision fastener component engineered to distribute load and ensure secure assembly in suspension and chassis applications. Designed for use with ALLSTAR PERFORMANCE's 2.25-inch polyurethane bushings, this washer serves as a critical interface between the bushing assembly and mounting hardware. Whether you're building a custom suspension system, restoring a classic vehicle, or maintaining performance equipment, a properly sized washer prevents bushing deformation, reduces fastener pull-through, and extends component longevity under dynamic loads.

Manufactured from durable aluminum, this washer offers an optimal balance of strength and weight savings compared to steel alternatives. The aluminum construction resists corrosion and galvanic reaction when paired with stainless steel fasteners, making it ideal for both street and competition vehicles exposed to moisture or road salt. The precision bore diameter is engineered to match ALLSTAR PERFORMANCE's 2.25-inch poly bushing specifications, ensuring a consistent fit that maintains proper clamping force throughout the suspension's range of motion without overtightening or crushing the polyurethane material.

This washer is ideal for suspension builders, fabricators, and enthusiasts installing adjustable control arms, sway bar links, and other bushing-equipped assemblies. It is compatible with any system using ALLSTAR PERFORMANCE's standard 2.25-inch poly bushings and works seamlessly with Grade 8 bolts and stainless hardware. Installation is straightforward—simply place the washer between the bolt head (or nut) and the bushing outer surface to distribute clamping pressure evenly. For optimal results, pair this washer with quality fasteners and apply moderate, even torque to avoid bushing deformation and ensure long-term suspension performance and alignment stability.
