Product Details

The ProX 29.890172 is a precision replacement valve shim measuring 8.90mm outer diameter x 1.72mm thickness, sold in a convenient 5-piece pack. Designed for use in KTM, Husqvarna, and Husaberg motocross and enduro engines, these shims are a critical component in maintaining proper valve clearance during routine engine maintenance.

Key Features:

  • Precision dimensions: 8.90mm OD x 1.72mm thickness for exact fitment
  • Specific heat-treatment process ensures maximum hardness, durability, and reduced wear
  • Precision machined to match exact OEM tolerances
  • Compatible with stock or aftermarket camshafts
  • Cost-effective replacement for expensive OEM shims
  • Sold in a 5-piece pack for multiple adjustments or builds

ProX valve shims are the go-to choice for engine builders and service technicians who demand reliable, consistent valve train performance. Having a supply of the correct shim size on hand streamlines valve adjustment intervals and minimizes downtime.
