Hot Cams Complete 9.48mm Valve Shim Kit

The Hot Cams Complete 9.48mm Valve Shim Kit (HCSHIM02) is a mandatory shop staple for anyone performing routine valve clearance adjustments on modern, large-displacement 4-stroke motorcycles and ATVs. Featuring a 9.48mm outer diameter (often referred to as 9.4mm in manufacturer manuals), this comprehensive kit covers the clearance requirements for a massive range of 400cc+ Japanese engines.

Each shim is manufactured from premium forged 4140 steel to withstand the immense, repetitive impact of the engine's camshaft lobes without fracturing or compressing over time. The kit provides a complete size run from 1.20mm up to 3.50mm in precise 0.05mm increments. To ensure accurate tuning and eliminate guesswork, every individual shim features its thickness permanently laser-etched onto the face. The entire assortment is housed in a durable, compartmentalized plastic storage case to keep the sizes strictly organized in your toolbox.

Features:

• Forged Construction: Manufactured from cold-forged 4140 steel for exceptional durability and resistance to flattening under high-RPM cam impact.

• Complete Size Range: Includes shims ranging from 1.20mm to 3.50mm in strict 0.05mm increments (47 different sizes).

• Multi-Pack: Contains three (3) individual shims of every single size, allowing you to easily adjust multiple valves that require the same thickness.

• Laser-Etched: Each shim features a high-contrast, laser-etched thickness measurement for quick visual identification.

• Shop Organizer: Packaged in a heavy-duty, compartmentalized plastic storage case that prevents sizes from mixing during transport.
