Supertech lash cap conversion spring kits are engineered for applications that convert to running lash caps on the valve stem tips. Each kit is designed around the corrected valvetrain geometry, with springs, retainers, and hardware matched to maintain proper installed height and pressures with lash caps in place.
Lash caps protect the valve stem tip — critical when running titanium valves — and are used to set correct geometry in converted valvetrains. These kits take the guesswork out of the conversion by supplying components engineered to work together.
For engine builds converting to lash caps, including titanium valve installations and applications requiring corrected valvetrain geometry. Consult the fitment listing for your specific engine.
