Frequently Asked Questions

Q: What does the 9.48mm measurement refer to?
A: This is the outside diameter (O.D.) of the shim. It is the most critical dimension to ensure the shim fits correctly inside your valve bucket or retainer.

Q: How many shims are included in total?
A: The kit includes 141 shims in total, with 3 shims for each of the 47 size increments (1.20mm to 3.50mm).

Expert Pro-Tip: Always double-check your valve clearance after installing the new shim and rotating the engine by hand several times. Heat expansion is real—if you're on the tighter side of the spec, it's safer to go a step thinner. Tight valves are what burn seats and drop heads, not loose ones.
