Oversized for a Reconditioned Crankshaft

When a crankshaft’s main journals are machined slightly undersize during a rebuild, standard-size bearings won’t provide correct clearance. ACL’s 0.005mm oversized main bearings are built specifically for that scenario, restoring proper oil clearance after machining work.

Thrust-Bearing Design at Position #5

This set is configured with the thrust-bearing surface at the #5 main position, matching the EJ-series engine’s thrust bearing location for correct crankshaft end-play control.

• High performance main bearing set, 0.005mm 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

Make sure your machinist specified 0.005mm oversize for your crankshaft rebuild before ordering this is a precision part matched to a specific machining spec, not a universal bearing.
