What is the purpose of valve lock keepers?

Valve lock keepers, also known as valve locks or retainers, work with the valve spring to keep the valve seated properly. They fit into grooves on the valve stem and hold the valve spring retainer in place, preventing the valve from coming loose.

What does the '10 DEG BEAD' specification mean?

The '10 DEG BEAD' refers to the angle of the keeper's locking surface and the valve stem groove it engages with. This specific angle is designed to match certain valve stem retainers and ensure a secure fit within the valvetrain geometry.

What does the '.3415 BEAD' specification mean?

The '.3415 BEAD' refers to the inner diameter of the valve lock keeper, which is the size of the valve stem it is designed to fit. This measurement ensures a snug and secure fit onto the valve stem, preventing any looseness or potential failure.
