Tappet Shim 1289269G10233

Ensure accurate valve clearance and optimal engine performance with the genuine tappet shim (part 1289269G10233). This precision-machined hardened steel shim fits directly under the cam follower, providing the correct lash specification for smooth idling, efficient combustion and extended tappet life.

Key Benefits

• Exact OEM Specification
  Manufactured to Suzuki’s original dimensions and tolerances for a perfect fit under the tappet bucket—no machining or modification required.

• Hardened Steel Construction
  High-strength alloy steel resists wear and maintains thickness under repeated valve cycles, ensuring consistent clearance over time.

• Precision Thickness Control
  Available in calibrated thickness increments to achieve factory valve lash settings, optimizing power delivery and fuel efficiency.

• Engine Smoothness & Longevity
  Correct valve lash reduces noise, prevents cam lobe damage and extends service intervals for the entire valvetrain.

Vehicle & Engine Compatibility

Fits Suzuki models and engines requiring shim-type valve adjustment using part number 1289269G10233, including but not limited to:

• Suzuki GSX-R600/750 (2006–2015)
