Valve Spring Shim Kit 1.250" O.D .015", .030", .060" Thickness. .814" I.D
Used to equalise installed height of valve spring
Made from the highest quality shim stock
Available in three different thicknesses to help achieve proper valve spring height
Available for many different spring diameters

Valve Stem Oil Seals .500" Guide Size, Stock Valve Size Steel Jacketed Viton Seal for LS1
Comp Cams offers a complete line of valve stem seals, a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The O ring seals use the standard retainer and oil splash shield. The umbrella seal is normally used when a larger than stock diameter spring is used, and in the case of a double spring, the positive top Teflon seal is used. Smaller diameter Viton seals are also available for triple spring applications. Both the O ring and the umbrella seals require no machining , but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special cutter.

10 ° Lightweight Tool Steel Retainers 1.437" - 1.500" Valve Spring Diameter
CNC - machined for consistent quality
Developed using latest FEA and CAD software
Spintro tested to extreme rpm to prove strength is equivalent to titanium and stronger than chromemoly steel

Spring ID Locator .060" Locator Thickness Locator ID .570", OD 1.625", Spring OD N/A, ID .765"
COMP Cams Spring ID Locators will not only protect the head and shim, but also locate and hold the spring in place. Previously, this part has been available only in a cup form with the retaining portion being on the outside of the part. This required that the head be machined a great deal to accept this cup. A new I.D. locator with the locating shoulder on the inside is now available.

7° Machined Valve Locks Single Groove 11/32" Valve Stem Size
COMP cams machined 7° race locks are recommended for race and performance street applications with high spring loads. They offer the same valve spring location accuracy as our Super locks without the need to change to 10° retainers.

Improve surface mating of rotating assembly, rod journals, piston rings, valve guides, camshaft and lifters, etc.
Protect all internal engine components, including flat tappet and roller valve trains.
Proprietary additive package includes optimum amounts of ZDDP (Zinc and Phosphorous), Molybdenum and detergents.
Require no additives or supplements for maximum protection.
Fully compatible with gasoline, methanol and high octane race fuel.
Due to government regulations, in recent years oil manufacturers have removed the zinc and many of the other additives from their motor oil. However, using an “off-the-shelf” brand of oil during the critical break-in process can lead to a failure. Thus, COMP Cams® Engine Break-In Oil Additive is designed to extend the durability of internal engine components including camshafts, valve train components and all moving parts in your new or rebuilt engine. It does so by using a special blend of extreme pressure additives no longer available in “off-the-shelf” motor oils. COMP Cams® Engine Break-In Oil provides added protection during the break-in process and is compatible with any petroleum, synthetic or blended motor oil.

Billet LS Belt Tensioner
Suit GM LS1 - LS7
The GM LS engines with the factory spring loaded belt tensioners become prone to throwing belts when used in performance applications and with after market balancers. These bolt-on Billet LS Belt Tensioners are a fully adjustable solution for controlling potentially damaging resonance and maintaining desired belt tension.
