Hardened Single Groove Down Locks, Sold in Half Sets

These are sold in half sets of 16 halves which is enough for 8 valves. If you need enough for 16 valves, simply order quantity of two.

Down locks are designed to offer LESS installed height.

These are the .070" down version. *

The main reason to use down locks is when there is way too much installed height w/ Std locks and the installer doesn't want a tall stack of shims.

Some applications have a stepped spring base which only accept a certain amount of shims before the step is lost. These applications need the step to locate the spring so down locks are a smart choice.

Many Ford applications use a stepped spring base.

Specially manufactured for added strength, these Down locks are great for most many performance applications.

If you look at the pictures, you can see the locator bead is offset upward.
