The ACL Race Suzuki M15A/M16A/M18A main bearing set 0.25mm is a main bearing set for Suzuki M15A/M16A/M18A engines. Compatibility here refers to these engine codes as listed in the product naming.
The 0.25 mm size variant matters most when it matches your measured crankshaft and housing dimensions and your intended bearing clearance. Clean assembly, undamaged bearing seats, and consistent clearance checks help keep the final fit repeatable.

Selection & installation tips
- Measure the journals: measure crank main journals in multiple positions and match the result to the selected size variant.
- Check housing seats: inspect block saddles for surface condition, clamping, and roundness, as this affects final clearance.
- Verify clearance: check bearing clearance at each main position during assembly and keep bearing halves paired.
- Align oil feeds: ensure oil holes and galleries are clean and that the bearing position does not block the oil path.
- Match markings: confirm markings on bearings and packaging match the chosen 0.25 mm variant before installation.
Before installation, compare your measured journal sizes, housing condition, and clearance target to the selected 0.25 mm variant, then confirm markings and clearances during assembly so the set matches your engine’s actual dimensions.
