CompCams

The stress placed on cams and timing gears has produced a weak area at the front of the block where the cam gear rubs against it. This one piece encapsulated thrust bearing solves this problem. Machining is necessary when used with oem type timing set, but it can be done with relative ease.

CompCams

In some endurance uses & most oval track applications, it is necessary to use a rev kit for the lifter to follow the profile of the cam. In the event of a push rod or rocker arm failure, the lifter will not come out of the lifter bore. This could save a loss of oil pressure and major damage to the engine. The kit comes with all required springs & buttons.

CompCams

The standard cast iron gear is not compatible with a steel roller cam. Comp Cams gears are machined from AMPCO-45 extruded aluminium bronze with 5% nickel added. These gears feature a high strength tooth design that will resist wear even when a heavy duty oil pump is used. Carbon Ultra-Poly Composite gears have 300% increased durability over bronze gears, when used with a steel camshaft. Proven in NASCAR racing to give precise timing & extended durability.

CompCams

Holds the lifters in place, in an oem block.

The offset bushes can be used to advance the cam for increased low-end torque and mid-range horsepower, or to reduce excessive low-end torque and increase top-end horsepower by retarding the cam. They can also be used to more accurately set the standard cam timing. Cam sprocket dowel pin hole must be drilled.

CompCams

Cam thrust buttons go between the cam timing gear and the inside of the timing cover. They are mandatory with race roller cams, as the lobes are ground flat, not tapered like flat tappet cams. This taper, drags the cam into the block when the engine is started up. OEM roller cams normally have a retaining plate, and do not need a button. Cam buttons can be used with all types of camshaft if the engine is used for Racing. The thrust button controls the fore & aft movement of the camshaft, ensuring more accurate ignition timing, and less wear on other components.
