Hourglass Spacers 1/2in IDx1-1/2in OD x 1/4in

The Allstar Performance Hourglass Spacers 1/2in ID x 1-1/2in OD x 1/4in (ALL 18830) are precision aluminum spacers engineered for suspension geometry correction and wheel offset adjustment in performance and racing applications. Supplied as a pair, these hourglass-profile spacers distribute load evenly across wheel hubs while maintaining critical suspension angles during high-performance driving or track use.

The 1/2-inch inner diameter accommodates standard wheel hub bolt patterns, while the 1-1/2-inch outer diameter provides a broad bearing surface against the hub and wheel interface. At 1/4-inch thickness per spacer, this specification delivers adequate material mass for structural integrity without introducing excessive unsprung weight. The natural aluminum finish resists corrosion in typical automotive environments and can be anodized for enhanced durability if required. Each spacer weighs 0.11 lbs, keeping the overall suspension system responsive and reducing rotational inertia.

These spacers are commonly used in circle-track racing, street performance builds, and suspension tuning where precise wheel offset or brake clearance adjustments are needed. They install between the wheel hub and wheel, allowing builders and tuners to dial in geometry changes without replacing entire hub assemblies. The universal design fits most domestic and import vehicle platforms with 1/2-inch bolt-hole spacing, making them a core spacer option in performance suspension shops and racing garages.

Allstar Performance is recognized in the racing and performance aftermarket for manufacturing precision aluminum components to tight tolerances. These hourglass spacers meet the dimensional standards expected in professional racing environments where suspension accuracy is non-negotiable. Always verify clearance with brakes, bearings, and other hub-mounted components before final installation.
