Alecular SI Bearings Aluminum based, bi-metal bearings were specifically developed for drag racing where short duration, high load conditions are the norm. Bearings feature high embedability and up to 10,000 PSI of fatigue resistance. Specify size (Standard, -.010”, -.020” or -.030”) when ordering.

Similar in construction and design to the above Alecular SI Bearings, Pro Series are designed for use with aftermarket crankshafts where narrowed bearings are required due to reduced fillet clearance. Bi-metal, aluminum based bearings offer high embedability and up to 10,000 PSI of fatigue resistance. Narrow design provides compatibility with crankshafts that include large radii.
