Hot Cams 9.48mm Complete Shim Kit for ATV Engines — 4140 Steel, Laser-Etched (Regular)

Hot Cams 9.48mm Complete Shim Kit HCSHIM02 is a full set of valve shims (1.20–3.50mm in 0.05mm steps) forged from 4140 steel and laser-etched for fast identification.

Keep your ATV’s valve clearances accurate with a comprehensive shim assortment engineered for popular sport and utility models. This kit supplies three shims in every increment from 1.20mm to 3.50mm (0.05mm spacing), enabling precise valve lash adjustments during routine maintenance, head work, or performance rebuilds. Constructed from durable 4140 steel and laser-etched with the size on each shim, the set is built for repeat use and quick selection at the bench.

Which ATVs will this shim kit fit?

The HCSHIM02 kit covers many common four-wheeler models across Arctic Cat, Honda, Kawasaki, Suzuki and Yamaha, matching the 9.48mm valve shim seat size used in these engines. Check your engine’s service manual for shim diameter and the manufacturer-recommended clearance specs before ordering.

• Arctic Cat DVX 400 (2004–2008)
• Honda TRX 450ER (2006–2014) and TRX 450R (2004–2009)
• Kawasaki KFX 400 (2003–2006) and KFX 450R (2008–2014)
• Suzuki LT-R 450 (2006–2009) and LTZ 400 (2003–2013)
• Yamaha YFZ 450 series (2004–2017 models listed)

How does this kit make valve maintenance easier?

With three shims at every 0.05mm increment, you can quickly select combinations to hit target clearances without multiple trips to parts counters. Laser-etched sizing eliminates guesswork under shop lighting, and the 4140 steel construction resists deformation under repeated installation.

• Full range: 1.20–3.50mm in 0.05mm steps for fine adjustment
• Three pieces per size reduce inventory swapping during measurements
• Laser-etched sizes speed identification and reduce errors
• Forged 4140 steel increases longevity and consistent thickness

What should I prepare before using these shims?

Gather the correct feeler gauges, a micrometer or caliper for verification, valve spring compressor, torque wrench, and the model-specific service manual. Clean the shim seats and measure current clearances so you can calculate the exact shim thickness change required.

• Service manual for clearance specs and torque values
• Feeler gauges and micrometer for precise measurement
• Valve spring compressor and basic hand tools
• Clean work area and labeled trays to organize removed parts

Will these shims work for performance or OEM rebuilds?

The kit is suitable for standard maintenance, aftermarket tuning, or engine overhauls where shim-style valve adjustment is used. Because they are precision-forged and laser-etched, these shims are appropriate for both everyday rebuilds and higher-use applications—but always match material and thickness recommendations from your engine builder.

• Precision manufacturing supports repeatable clearance settings
• Wide thickness selection helps adapt to modified valve seats or spring changes
• Not a direct substitute for model-specific OEM material spec verification

Who is this for: This Hot Cams HCSHIM02 kit is intended for DIY mechanics, professional ATV technicians, and performance builders who service Arctic Cat, Honda, Kawasaki, Suzuki, or Yamaha 9.48mm shim-type valves. If you perform routine valve lash checks, engine rebuilds, or need a broad inventory of shim sizes to dial in clearances precisely, this complete, laser-etched, 4140 steel set streamlines the job and reduces repeated parts ordering.
