Tapered Spacers Aluminum 5/16in ID 1/2in Long

The Tapered Spacers Aluminum 5/16in ID 1/2in Long from ALLSTAR PERFORMANCE are precision-engineered aluminum spacers designed for high-performance engine and drivetrain assembly work. These tapered spacers serve as critical positioning components in applications where precise axial alignment and load distribution are essential. Whether you're building a racing engine, upgrading suspension geometry, or assembling custom drivetrain configurations, tapered spacers ensure consistent spacing and proper bearing preload across multiple mounting points.

Manufactured from lightweight aluminum, these spacers feature a 5/16-inch inner diameter (ID) and 1/2-inch thickness, designed to accommodate standard fastener sizes while maintaining structural integrity under stress. The tapered design allows for progressive load distribution and accommodates slight misalignment without compromising fit or function. Aluminum construction provides an optimal balance of strength and weight reduction—critical for motorsports applications where every fraction of a pound matters. The natural finish resists corrosion in typical engine bay environments while remaining compatible with common fastener types and assembly procedures.

These spacers are ideal for engine builders, suspension technicians, and performance enthusiasts working on universal applications where standardized spacing is required. The pair configuration ensures matched components for dual-point assemblies, eliminating guesswork during complex builds. Installation is straightforward—spacers slide onto fasteners and position components at precise depths, essential for maintaining correct bearing preload, gear mesh patterns, and suspension geometry. Compact dimensions make storage and inventory management simple for shops and serious hobbyists alike.
