Use on aftermarket heads w/ 1.00"-1.020" ID beehive springs

Beehive Valve Spring Locators, large OD

Fits select large OD beehive springs.

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

These fit the bigger beehive springs like PAC #1220 & 1286 (1.445"OD/1.00" ID & 1.405" OD/1.00" ID)

The base thickness is .050" which offers .010" more available installed height over .060" base versions.

Fits aftermarket heads w/ .558"-.565" OD guides.

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 been a well kept industry secrete used by successful professional 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.

Customers can add in a full set of 16- 11/32" X .530" Viton valve seals for only $9.99 Use optional check box towards the top of page.
