Shaft Collar 1-1/4in

The Shaft Collar 1-1/4in from Allstar Performance is a precision mechanical fastener designed for engine builders, fabricators, and performance enthusiasts who demand repeatable positioning on rotating or stationary shafts. This collar is essential for assembling custom engines, tuning race cars, or fabricating transmission components, providing a secure and adjustable mounting point.

Featuring a split-ring design with a setscrew, this collar clamps directly onto the shaft, distributing clamping force evenly without marring the underlying component. The engineering behind this solid shaft collar ensures zero slippage under rotational load, which is critical for applications such as cam drives, alternator mounts, or custom throttle linkages.

This collar accommodates any 1-1/4 inch diameter shaft and is compatible with steel, aluminum, or composite materials commonly used in custom engine work and transmission modifications. Installation is straightforward, making it a reliable choice for both street and competition builds.
