Lash Caps - 11/32 .090 Deep

The Crower Lash Caps – 11/32 .090 Deep (Part No. 86121-16) is a professional-grade valve lash cap set engineered for precision engine tuning and maintenance. These chromoly lash caps are designed for valve stems measuring 11/32 inch, with a 0.090-inch thickness that provides the structural rigidity required for accurate valve lash adjustment in high-performance and stock engine applications. Supplied as a set of 16 pieces, these caps enable mechanics and engine builders to establish and maintain proper valve clearance across all cylinders.

The 0.090-inch thick profile is critical for preventing cap deformation under the pressures and thermal cycling inherent to engine operation. Chromoly construction—an alloy of chromium and molybdenum—delivers superior hardness and wear resistance compared to standard steel, reducing the risk of cap damage during repeated adjustments or under sustained load. The natural finish reflects Crower's focus on functional durability rather than cosmetic treatment, ensuring the caps resist corrosion during storage and use. The 11/32-inch valve stem size is a common specification across many small-block and mid-range engine platforms, making these caps compatible with a wide variety of applications from street engines to track-built powerplants.

Engine builders, mechanics, and enthusiasts performing top-end work rely on lash caps to protect valve stems during adjustment procedures and to maintain precise clearance specifications. Proper valve lash is essential for optimizing valve timing, preventing valve float at high RPM, and ensuring consistent combustion. The Crower set supplies enough caps for complete cylinder coverage on most domestic and import engines, reducing downtime and the need for multiple purchases. Whether tuning a daily driver or preparing a competition engine, accurate valve lash measurement and adjustment using quality caps like these ensures reliable operation and longevity.
