Hot Cams Valve Shim 9.48 x 2.80 for Honda CRF450R 2002-2014 5PK948280

Valve clearance directly impacts combustion efficiency, engine longevity, and power delivery—and shims are the most reliable way to dial in precise adjustments on your CRF450R. Whether you're fine-tuning a stock rebuild or optimizing a performance build, having quality shims on hand prevents downtime and ensures your valvetrain operates within manufacturer specifications. This 5-pack from Hot Cams gives you the flexibility to experiment with clearance settings without waiting for backorders.

Hot Cams has built their reputation on precision-engineered valve components, and these shims are no exception. The 9.48 x 2.80 dimensions are engineered for the CRF450R's bucket-style valve arrangement, ensuring a perfect fit without rocking or binding. Each shim is manufactured to tight tolerances and finished with a hard anodized surface that resists wear and corrosion even under sustained high-RPM operation.

Installation is straightforward—remove the valve cover, rotate the crankshaft to TDC, measure existing clearance, and swap shims as needed. No special tools required beyond a feeler gauge and basic socket set. Bolt-on simplicity meets genuine performance tuning.
