LASH CAPSCrower lash caps protect the ends of your valves from excessive wear

and help to correct rocker geometry by increasing rocker arm to retainer

clearance. Machined from high grade chromoly steel and heat-

treated for added strength, Crower lash caps give your valves an added .060" margin of protection. Highly

recommended for performance applications, and a must for costly stainless steel or titanium valves.

VALVE STEM SEALSCrower valve stem seals provide

correct oil control at the valve guide. The spring loaded wiper design

prevents unwanted oil contamination on the cylinder. Heavy-duty steel and

teflon construction.

Also available in singles by replacing -16 with -1.

BILLET PERFORMANCE 7°VALVE STEM KEEPERS

Crower billet performance valve stem keepers are precision machined from

premium billet bar stock chromoly steel. Heat-treated for maximum

strength to insure against shoulder shearing (common with stock and lesser quality keepers). In addition

to our standard height, we also offer .050" higher and .050" lower to achieve the correct installed spring
