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.

Alecular Pro Series Bearings
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. Specify size (Standard, -.010”, -.020” or -.030”) when ordering.

Xtreme Performance Tri-Lecular Bearings
Designed specifically for applications that are subject to high bearing loads, Xtreme Performance tri-metal bearings feature the
addition of a copper intermediate layer, strengthened with tin, that results in a 24% stronger overlay and 17% increase in fatigue
resistance. A narrow design make Xtreme bearings compatible with all crankshafts, including those with large radii. Specify size
(Standard, -.010”, -.020” or -.030”) when ordering.
