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 with 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 inter-
mediate 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.
