Hot Cams 9.48mm Complete Shim Kit HCSHIM02 for ATV Valve Adjustment — 4140 Steel, 1.20–3.50mm in 0.05mm Steps, 3pcs Each

Hot Cams 9.48mm Complete Shim Kit HCSHIM02 is a full set of precision-forged 4140 steel valve shims (1.20–3.50mm in 0.05mm steps) designed to restore correct valve clearances on specified ATV engines.

Keep your ATV's valve lash within specification without hunting for single sizes — this Hot Cams shim kit supplies three of each increment so you can dial in precise clearances quickly. Each shim is laser-etched with its size for fast selection, and the hardened 4140 steel construction offers consistent thickness under heat and repeated service. The kit covers popular sport and utility models from Arctic Cat, Honda, Kawasaki, Suzuki, and Yamaha spanning mid-2000s through mid-2010s model years.

Will this shim kit fit my ATV model and year?

The HCSHIM02 kit is built to match shim dimensions used by many four-stroke ATV cylinder heads in the listed model range. Verify your engine uses 9.48mm-type shims and check the production years; the kit lists compatible models and years for quick confirmation.

• Includes sizes 1.20–3.50mm in 0.05mm increments, three shims per size.
• Compatible with Arctic Cat DVX 400 (2004–2008) and multiple Honda, Kawasaki, Suzuki, Yamaha models noted in the product details.
• Works for engines that require 9.48mm shim diameter specifications.

How do these shims help during a valve adjustment?

Swap shims to correct valve clearance without machining or guesswork. The three-shim-per-size supply allows you to mix sizes to reach the exact clearance and retain a spare for future adjustments.

• Laser-etched sizes speed selection and reduce installation errors.
• Three shims per size give flexibility for pairing and stacking where needed.
• Precision 0.05mm increments let you achieve tight tolerances called for in service manuals.

What materials and quality features does the kit include?

Hot Cams forges the shims from 4140 alloy steel known for toughness and dimensional stability under heat. Each piece is heat-treated and laser-marked so size identification endures workshop conditions and repeated use.

• Forged 4140 steel construction resists wear and deformation.
• Heat treatment for consistent spring-back and thickness retention.
• Laser etching maintains legible sizing even after cleaning and handling.

How do I use the kit effectively during service?

Measure current valve lash with feeler gauges, consult the service manual target clearance, then select the closest shim size or combine shims to reach the target. Recheck clearance after installation and torqueing to ensure it remains within spec.

• Always measure hot/cold as specified by your service manual.
• Record original shim sizes before removal to speed replacement decisions.
• Keep a clean work area to prevent grit from damaging shim surfaces or seats.
