The kit focuses on essential system upgrades (ignition, fuel, cooling, exhaust). Piston rings and oil rings are wear items that depend on your engine's current condition. If your V8-44 runs well with good compression and no excessive oil consumption, the existing rings may still be serviceable. However, if you notice oil consumption or low compression during installation, we recommend replacing them. Contact service@stirlingkit.com for compatible piston ring and oil ring options.
