## Description

ACL Race Series bearings with a 0.25 mm repair rib are designed for Renault F4R R3 engines with a slightly ground crankshaft. Their tri-metal alloy composition (hardened steel, copper, lead/tin) makes them extremely robust and able to withstand the extreme stresses encountered in competition use.

Designed for even oiling, reduced friction and efficient heat dissipation, these bearings ensure maximum low-end engine life, even at high revolutions per minute.
