Hourglass Spacers 3/8in ID x 1in OD x 1/2in Long

The ALLSTAR PERFORMANCE Hourglass Spacers 3/8in ID x 1in OD x 1/2in Long are precision aluminum spacers designed for suspension and drivetrain assembly work across a wide range of automotive and motorsports applications. These spacers are manufactured to tight tolerances, ensuring they meet the demands of high-vibration environments where dimensional accuracy is crucial for safety and longevity.

With a 3/8-inch inner diameter, 1-inch outer diameter, and 1/2-inch thickness, these spacers provide the geometric precision required for various automotive components. The hourglass geometry, which is narrower at the center and wider at the shoulders, helps to distribute loads evenly and reduce edge loading, thereby extending the life of the components under cyclic stress. The natural aluminum finish also resists corrosion in typical automotive service conditions.

These spacers are ideal for drag racing, street rod, circle-track, and general automotive repair operations where precise spacing is necessary. Technicians and builders rely on ALLSTAR PERFORMANCE spacers for their ability to achieve precise bore concentricity and repeatable stack heights without the need for custom machining.
