Product Description

For on aftermarket heads using aftermarket beehive springs

Valve Spring ID Locators

 

Use with aftermarket springs w/ .885"- ID

 

Our custom design locators are machined from 4140 chrome moly steel then heat treated to improve resistance to wear.

These have a .045" base thickness which offers .015" more available installed height over common .060" base versions.

Fits most aftermarket heads w/ .558"-.565" OD guides. Use with aftermarket beehive springs w/ .885" bottom side I.D.

This design offers increased valve spring stability by supporting more of the spring. Modern OEM cyl head engineers have been incorporating taller locating wall designs to dampen springs without the need for internal flat wire dampers. In essence, the tall wall design limits lateral movement at full lift where more coils are contained compared to std wall height locators. This technology is not well known, it's one of many well kept industry secrets used by successful race engine builders.

Purchase comes with 16 locators as well as one shortened version, know as a "modified locator". The modified locator is used only as a tool when measuring installed heights. Since our locators are taller, the modified locator is needed to function with common installed height mic's. When measuring installed heights, use the modified locator. Once the target height is established, replace with one of the 16 locators and so on.
