MUYIDP 47-Piece 7.48mm Valve Shim Kit — Precision for Dirt Bike Maintenance

Maintaining precise valve clearance is a cornerstone of reliable engine performance. The MUYIDP 47-piece valve shim kit is designed to support routine valve maintenance, race prep, and field service on a range of popular dirt bikes. Each shim is forged from carburizing steel to withstand repeated valve cycles, helping you sustain consistent clearances over time. The kit uses a fixed 7.48 mm diameter across all pieces, while the thickness spans from 1.20 mm to 3.50 mm in 0.05 mm steps. This combination gives you a broad, granular selection for dialing in gaps across different engines and wear states, without needing to source individual shims from multiple vendors. The top surfaces of each shim are labeled with the corresponding size for quick identification, keeping your workflow efficient in the shop or pit.
