Tapered Spacers Aluminum 5/16in ID 1/4in Long

The Allstar Performance Tapered Spacers Aluminum 5/16in ID 1/4in Long are precision-engineered components designed for applications requiring exact geometry in high-vibration environments. These aluminum spacers are ideal for engine builders and performance enthusiasts who need reliable standoff distances to prevent component interference.

Constructed from lightweight aluminum, these tapered spacers feature a 5/16 inch inner diameter bore and a length of 1/4 inch. The tapered design allows for slight misalignment while maintaining structural integrity under thermal cycling and vibration loads, making them suitable for various automotive applications.

Engine builders and performance tuners can rely on these aluminum spacers to address fitment gaps in applications such as intake manifolds and accessory mounting. Their precision manufacturing ensures consistent fit across production runs, which is critical for those assembling multiple engines or replacing components mid-season.
