11/32in Lash Caps

The 11/32in Lash Caps from MANLEY represent a critical wear item for engine builders, performance technicians, and serious enthusiasts who demand precision valve train geometry. These lash caps function as adjustable spacers that sit atop valve stems, allowing mechanics to dial in exact valve lash clearances during initial engine assembly or top-end service work. Proper lash adjustment is essential for optimal cam profile utilization, preventing valve float at high RPM, and protecting against catastrophic valve-to-piston interference.

Each set includes 16 steel caps manufactured to exacting tolerances, featuring a 0.080-inch thickness that ensures consistent material behavior under thermal cycling and valve train load. The 11/32-inch stem diameter specification matches common small-block and mid-block engine platforms, while the 0.250-inch minimum tip dimension provides adequate contact surface for adjuster screw or rocker arm geometry. Steel construction resists deformation under the repetitive impact forces inherent to pushrod and overhead cam valve trains, and the natural finish resists galling when stacked or adjusted multiple times during the setup process.

Technicians restoring vintage Chevrolet, Ford, Chrysler, and other domestic performance engines will find the 11/32in Lash Caps indispensable for matching OEM or aftermarket cylinder head specifications. Installation requires removal of the rocker arm assembly and careful measurement of existing lash, then selective stacking of caps to achieve target clearance values before reassembly. Because lash directly affects fuel mixture quality, idle stability, and sustained power delivery, precision components from MANLEY ensure your valve train delivers the geometry your cam profile demands.
