Key Features & Benefits – King Racing Suzuki main bearing set
The King Racing Suzuki main bearing set is a crankshaft main bearing set for Suzuki M15A/M16A/M18A 1.5/1.6/1.8L 16V DOHC engines. It can be used across multiple vehicle lines where those engines were fitted and the correct bearing size is selected to match measured dimensions.
The XP line uses a pMaxBlack™ overlay with a tri-metal (copper-based) structure, supplied as 5 pairs. The series includes U-Groove™ and Radialock™ features that support oiling geometry and bearing seating.
When is this useful?
It is useful during an engine build or main bearing replacement when you want to choose a bearing size that matches your measured crank and housing, then verify oil clearance and free crank rotation after assembly.

Selection & installation tips
- Engine code check: confirm the engine is M15A/M16A/M18A before ordering.
- Select the size: choose STD / STDX / .026 / 0.25 after measuring crank journals and planning target clearance.
- Oil clearance control: measure oil clearance during assembly and ensure consistency across all main positions.
- Oil feed & cleanliness: verify oil hole alignment and clean oil galleries and saddles before installation.
- Seating & torque: torque main caps in the OEM sequence, then check free crank rotation and end play.
Before final assembly, match engine code, measured crank/housing dimensions and the chosen STD/STDX/oversize option to the specifications listed above to confirm correct fit.
