## 🛠️ Service Notes

-   This kit's fitment is limited to D9A2L MH and D9A2M MP for piston classification 1-3, a far narrower list than the 136-application ring kit also listed under this item type — confirm the exact engine designation and the piston class stamped on the piston crown before ordering
-   Six kits are required to complete one D9A/D9B engine, one per cylinder — order the full quantity needed rather than one kit at a time, and do not mix with the 0.50 mm oversize kits also listed here
