The ALLSTAR PERFORMANCE Hourglass Spacers 5/16" ID x 1" OD x 1/2" are precision-engineered aluminum spacers designed for suspension geometry correction, wheel hub alignment, and drivetrain component spacing in modern performance and custom vehicle builds. These hourglass-profile spacers are essential for mechanics and enthusiasts who need precise axial spacing when working with wheel bearings, brake components, or transmission assemblies.
The distinctive hourglass geometry distributes load evenly and provides superior rigidity compared to flat spacers, making them a trusted choice across drag racing, street performance, and restoration shops. Manufactured from durable aluminum alloy, these spacers offer excellent machinability and corrosion resistance while maintaining a minimal weight footprint—important for vehicles where unsprung mass directly impacts handling and acceleration.
These hourglass spacers excel in applications requiring precision hub spacing and are compatible with standard shaft and bolt applications due to their 5/16" inner diameter bore. The 1" outer diameter provides lateral stability and load distribution, while the 1/2" overall thickness ensures critical spacing tolerances for optimal performance.
