Gen III Hemi Oil Pan Swap Kit - Mid Sump

The Gen III Hemi Oil Pan Swap Kit – Mid Sump from Holley is engineered for builders and mechanics converting or upgrading Mopar Gen III Hemi engines to a mid-sump oiling configuration. This retrofit kit addresses a critical cooling and pressure distribution challenge: factory deep-sump designs can create oil starvation during hard acceleration, cornering, or sustained high-RPM operation. By relocating the pickup point to a mid-level position and reducing overall pan depth to 6.4 inches, this kit maintains adequate oil volume (6 quart capacity) while improving scavenging efficiency and engine bay clearance for custom chassis or tight underbody layouts.

Built from cast aluminum and finished in black powder coat for durability and corrosion resistance, the Gen III Hemi Oil Pan Swap Kit integrates a redesigned baffle system, optimized pickup tube geometry, and internal tray structure to prevent oil surge and cavitation. The mid-sump design reduces the vertical footprint by over 2 inches compared to factory deep-pan units, critical for low-stance builds, custom frame fabrication, or chassis where transmission or driveshaft tunnel clearance is limited. Aluminum construction keeps rotating mass low while maintaining thermal stability, and the baffle configuration ensures consistent oil delivery during acceleration, braking, and lateral loading—essential for street performance, road racing, or autocross applications.

This kit is ideal for Gen III Hemi engine swaps into older Mopar platforms, modern restomod builds, or race car applications where factory pan geometry conflicts with custom fabrication. Installation requires engine bay clearance verification and compatible pickup tube mounting; consult Holley fitment documentation and your specific vehicle platform before purchase. The 6-quart capacity balances protection and weight, suitable for road use, autocross, and moderate track duty; extreme racing applications may require additional filtration or cooler capacity. Compatible exclusively with Mopar Gen III Hemi engines—verify your engine generation and mounting provisions to ensure proper fitment.
