Product Description

Down locks will produce .075" LESS Installed height compared to std locks

Hardened Single Groove Down Locks

Application: 11/32" Applications


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.

We offer two different versions of down locks. These are the .075" 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 the best choice.

Many Chrysler & Ford applications use a stepped spring base.

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

NOTE 2- There are certain applications where additional attention to detail is required. Applications where retainer to seal clearance is tight may not want to use down locks as it reduces clearance in this area. SB Chevy iron VORTEC heads are one such application. When installing down locks. be sure to verify retainer to seal clearance.
