Melling Camshaft Phasers
Melling camshaft phasers (aka, sprocket actuators or variable valve timing sprockets) are constructed from high-quality durable steel and shipped with the mounting bolt that attaches the camshaft phase to the camshaft. Sprocket actuators adjust the timing of the motor to ensure that you get the engine power you need, when you need it. The actuator dials the timing back when you don't require the additional power, restoring fuel economy and maintaining engine efficiency. Melling replacement camshaft phasers meet or exceed OE specifications for precise fit and function in their recommended application.

Enginetech Rebuilders Valves
For about the same cost of reclaiming valves, you can install brand new Enginetech Rebuilders valves. The purpose of these patented Enginetech Rebuilders valves is to help simplify engine rebuilding by salvaging worn cylinder heads and reducing the need for expensive parts like valve seats and springs. Designed with oversized heads and stems, and a lowered keeper groove, these specialized valves create a more efficient and cost-effective rebuild process. The Enginetech one-piece intake valves are made from HNV-3 high alloy valve steel (often used for exhaust valves). All of the valve stems are either triple chrome plated or gas nitrided. Enginetech even goes a step further and hardens every valve tip to 50HRC minimum. The Enginetech exhaust valves are also a one-piece design. All Rebuilder's exhaust valves are made from EV-8 or EV-12 stainless steel. Again, like their intake valves, all stems are triple chrome plated or gas nitrided. Wafer tips, hardened to 50RHc, are inertia welded to every tip. Select the valves you need for your engine rebuild.
