The Hot Cams Valve Shim Kit (HCSHIM02) is a complete, professional-grade 9.48mm OD valve shim assortment designed for serious valve maintenance on a wide range of ATVs, dirt bikes, dual-sport motorcycles, side-by-sides, and street bikes. Whether you're doing routine valve clearance checks on a Yamaha YZ 450 F, resetting valves after a top-end rebuild on a Honda CRF450R, or maintaining a Suzuki DR-Z 400, this kit gives you every shim thickness you need in a single purchase — no hunting down individual shims one at a time.

Key Features & Benefits

• Complete thickness range in one kit: Shims span 1.20 mm to 3.50 mm in precise 0.05 mm increments, so you can dial in exact valve clearance without ordering multiple part numbers.
• Three shims per size: With three shims included at every increment, you have enough inventory to service multiple valves or multiple machines without running short mid-job.
• Forged 4140 cold rolled steel construction: Each shim is forged from 4140 steel — a high-strength alloy chosen for its toughness — then heat treated to 55–60 HRC for improved strength and long service life under high-RPM valve train loads.
• Laser-etched size markings: Every shim has its thickness laser etched directly onto the surface, making identification quick and eliminating the risk of mixing up sizes during installation.
• Broad multi-brand fitment: One kit serves Arctic Cat, Honda, Kawasaki, Suzuki, and Yamaha applications, making it an ideal shop staple for technicians or riders who maintain more than one machine.
• Suitable for street, off-road, ATV, and adventure touring applications: Validated for use across riding styles including motocross, enduro, dual-sport, ATV/quad racing, and side-by-side utility vehicles.

Frequently Asked Questions

Q: What outside diameter (OD) are these shims?
A: All shims in the HCSHIM02 kit have a 9.48 mm outside diameter. Before ordering, confirm that your engine specifies 9.48 mm OD shims — this is the most critical dimension for proper fit in the valve bucket or retainer.

Q: How many shims are included and what thicknesses are covered?
A: The kit includes three shims at every 0.05 mm increment from 1.20 mm to 3.50 mm thickness. This gives you full coverage to adjust valves across a wide range of clearance measurements, with spares on hand for multi-valve or multi-bike jobs.

Q: Does the kit come with a storage case?
A: Yes. A storage case is included with the HCSHIM02 kit, helping you keep all sizes organized and protected between uses.

Q: Will this kit fit my Suzuki DR-Z 400 and my Honda CRF450R?
A: Yes — both models appear in the confirmed fitment list for the HCSHIM02. The Suzuki DR-Z 400 (all variants, 2000–present) and Honda CRF450R (2002–present) are among the most common applications for this kit. Always cross-reference against your service manual to confirm the 9.48 mm shim OD is correct for your specific year and variant.
