A Finer Oversize Increment

This ACL main bearing set uses a 0.002mm oversize, a finer increment than the 0.005mm version, for crankshafts machined to that more precise specification during a rebuild.

Same Thrust Configuration, Different Clearance

Like ACL’s other EJ-series main bearing sets, this one is configured with the thrust bearing surface at the #5 main position, differing from the 0.005mm version only in the amount of material removed to match your specific crankshaft machining.

• High performance main bearing set, 0.002mm oversized
• Thrust bearing configured for the #5 main position
• Compatible with EJ20, EJ22, and EJ25 engines
• For use with a reconditioned/machined crankshaft

The RallySport Take

Match this to your machinist’s exact oversize spec 0.002mm versus 0.005mm makes a real difference in bearing clearance, so don’t guess.
