The XRAY 358540 Flywheel Collar is built to secure the flywheel to your engine crank and maintain a precise alignment under load.
XRAY designed the collar to seat tightly on the crankshaft taper to reduce vibration and help protect bearings and seals from excess movement.
Whether used for club events or local track days, the XRAY 358540 serves as a straightforward replacement or upgrade across many common engine builds.
