K&L SUPPLY - 13-7663 - Replacement Valve Shims
Getting valve clearances right starts with shims that hold their thickness, and K&L Supply's 13-7663 replacement valve shims are rated to average 47.0 on the Apparent Rockwell Hardness C scale, ahead of the 46.0 maximum found on many original equipment shims. That added hardness means less wear-driven drift between valve adjustments on shim-adjusted engines, making this a practical upgrade to reach for the next time the shim bucket comes off for a clearance check.
