Shaft Collar 1in

The Shaft Collar 1in by ALLSTAR PERFORMANCE is a precision-engineered clamping collar designed for securing rotating shafts and components in high-performance automotive applications. Whether you're building a custom engine, assembling a performance transmission, or fabricating a specialized drivetrain system, this shaft collar provides the mechanical security needed to prevent unwanted shaft movement and component slippage. It's essential for mechanics and fabricators working on street rods, race engines, and aftermarket drivetrain modifications where reliability under load is non-negotiable.

This 1-inch diameter collar features a solid split-design construction that allows for tool-free installation and adjustment without requiring shaft removal. The clamping mechanism provides uniform pressure distribution around the shaft, eliminating the risk of stress concentration that can lead to premature bearing wear or shaft damage. Manufactured to ALLSTAR PERFORMANCE's exacting standards, the collar delivers repeatable holding power across multiple tightening and loosening cycles—critical when you're fine-tuning suspension geometry, adjusting belt tension, or performing repeated maintenance on high-output powerplants.

Ideal for professional mechanics, engine builders, and serious enthusiasts, this shaft collar works with 1-inch diameter shafts across a wide range of automotive and powersports applications. Its compact footprint (measuring 4.05 x 0.55 x 7.05 inches) makes it suitable for tight engine compartments and fabrication work where space is limited. Weighing just 0.14 lbs, it adds minimal mass while maintaining the structural integrity your build demands. Whether you're securing pulleys, coupling components, or positioning precision machinery, the Shaft Collar 1in delivers industrial-grade reliability at a practical price point.
