Hourglass Spacers 1/4in ID x 1in OD x 2in Long

The Hourglass Spacers 1/4in ID x 1in OD x 2in Long from ALLSTAR PERFORMANCE are precision-engineered cylindrical spacers designed for motorsport, automotive assembly, and mechanical applications requiring precise axial positioning. These spacers serve as critical spacing components in suspension systems, drivetrain assemblies, and wheel bearing setups where exact dimensional control is non-negotiable. Built by ALLSTAR PERFORMANCE—a trusted name in professional racing and high-performance automotive manufacturing—these spacers are engineered to maintain consistent geometry under load, vibration, and thermal cycling.

The 1/4-inch inner diameter (ID) accommodates standard bolt or shaft sizing, while the 1-inch outer diameter (OD) provides the bearing surface required for load distribution across mating components. At 2 inches in length, this spacer offers sufficient height for applications requiring moderate axial separation without adding excessive weight or footprint. The hourglass geometry—a narrower midsection with tapered shoulders—reduces stress concentration at transition points and allows for smooth assembly around fasteners and shafts. This design optimizes structural integrity while minimizing material weight, a critical consideration in both racing and field-deployed mechanical systems where every fraction of an ounce impacts performance and handling.

These hourglass spacers are ideal for professional mechanics, racing teams, and military or tactical vehicle technicians who demand repeatable, reliable positioning in high-stress assemblies. Installation requires straightforward insertion between mating surfaces, secured by the fastener pass-through the 1/4-inch bore. The compact 0.15-pound weight ensures minimal impact on vehicle dynamics or equipment balance. Compatible with standard metric and imperial bolt sizes, these spacers perform reliably in both controlled shop environments and field conditions, making them essential consumables for preventive maintenance and precision assembly across racing, off-road, and tactical platforms.
