KING

MB-557HP-020

KING MAIN BRNG 350 SBC .020

Your Cost: $63.99

Weight: 1.6 lbs

Tri-metal vs. Bi-metal Bearings

Traditional rod and main bearing construction is based upon a three layer configuration composed of a steel backing, a copper-lead layer and a very thin overlay of babbitt material only .0005 - .0008 thick. King’s bearing uses just two layers, a high strength steel backing plus a bonded layer of Alecular bearing material .012 - .015 thick.

Alecular material is used exclusively by King. It is an alloy of aluminum, tin, copper and several other elements. Because it is an alloy, it maintains its properties throughout its entire depth, delivering consistent and reliable performance.

Very popular among the Blown Alcohol and Nitro teams.

Note:
All Main Bearings we sell are Narrowed (for crank radius clearance)

-   X = Extra Oil Clearance

-  .001 .010  .020 are Undersize
(For Cranks that have been turned down)
