Description
Motorsport-grade main bearings that are well suited our range of steel crankshafts. These are heavier duty than the ACL Duraglide 780 range of bearings, thanks to an extra heat treatment process.
There are options to suit 1275 A-plus engines with 1.750″ big ends in standard and +10 sizes.
For Cooper S, Sprite/Midget and 998 engines with 1.625″ big ends, select the Cooper S/998 option, also in standard or +10 sizes.
