We Offer Corvair GM Stock Crankshaft Servicing. This service includes our 2nd Generation 5th Bearing.
We have sourced high quality shops that provide us with an excellent crankshaft rebuild. This process includes a stress relief process before grinding that eliminates stored stress in the crankshaft. This ensures the crankshaft will not require straightening after being Nitride treated. While many high quality shops straighten crankshafts after nitriding we feel it is a better practice to avoid the straightening process. The process of stress relieving the crank is expensive, but we feel it is well worth it.
The 5th Bearing Hub is a single piece 5th bearing Journal/Crank Gear for new engine builds. This unit will be welded to a new gear and pressed on as part of our Crankshaft Service. Then ground as a unit with the crankshaft. This will ensure concentricity with the crankshaft and eliminate the need for adjusting the run out during installation. Our 5th Bearing CNC Housing Kit is included with the Crankshaft Service.
