The precise fit of our lash caps and disks give your engine a superior valve-stem-to-keeper-to-retainer assembly.

Lash Caps and Lash Disks
Del West lash caps and lash disks are designed to minimize the traditional problems of fit and accuracy associated with these components.

The lash cap should be secure upon installation without having to be forced during the assembly. For the lash disk, the component should sit flat against the valve tip with good diameter and OD surface finish control to insure proper fit inside the retaining component. The result is a superior valve-stem-to-keeper-to-retainer assembly. When the fit is correct, there is no relative motion in the assembly. This results in less wear and an extended service life of the components.

Lash cap attributes:
• ID control of 0.0004" (0.010mm) ' Tighter control is available upon request or if required.
• Surface finish of Ra0.10um ' Tighter control is available upon request or if required
• DLC coated surfaces provided if required
• Crowned (domed) top surface available to insure center contact with actuating component
• Aerospace, through-hardened, medium-carbon steel for extended use and wear resistance

Lash disk attributes:
• OD control of 0.0004" (0.010mm) ' Tighter control is available upon request or if required
• Top and bottom surface finish of Ra0.10um ' Tighter control is available upon request or if required
• DLC coated surfaces provided if required
• Crowned (domed) top surface available to insure center contact with actuating component
• Aerospace, through-hardened, medium-carbon steel for extended use and wear resistance
