Description
Maintaining proper valve clearance is critical to engine reliability and performance—even a few thousandths of an inch off can cause misfires, valve float, or catastrophic damage. MOOSE Racing’s 8.90 mm valve shim kit eliminates guesswork with individually laser-etched identification, so you can dial in your valve train with confidence. Built from 4140 cold-rolled steel for durability and precision, these shims are engineered to hold tight tolerances through countless heat cycles.
