Enginetech Rod Bearings

Enginetech rod bearings are made of high-quality alloys, based on the application requirement. They are made on state of the art equipment, ensuring consistent bearing thickness for proper oil clearances, and parting line chamfers are precisely controlled, ensuring they are cut at the correct angle to allow for the proper amount of oil bleed-through without reducing oil pressure. The materials are high strength (load capacity), but also have good anti-friction properties (wear resistance, anti-seizure, and embeddability). Enginetech rod bearings provide extra protection and better durability within your rebuild. Select the size needed.

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.
