Mountune's extensive knowledge of the Ford EcoBoost engines coupled with our comprehensive motorsport experience provides the foundation for our high performance 4.1L Ford EcoBoost short block assembly.
Each short block starts off as a brand new aluminum Ford F-150 Raptor open deck engine block that has been precision machined in house to accept Darton MID Sleeves before being skillfully assembled with mountune forged pistons, forged h-beam connecting rods, tri-metal racing bearings, and a forged steel crankshaft.
The Darton MID Sleeve is a proven method of strengthening open deck engine blocks while maintaining OEM integrity. It prevents cylinder cracking, walking, and bell mouthing and allows for a much larger cylinder bore size.
This engine is the perfect foundation for your F-150 Raptor for high boost applications or as a direct replacement for your tired original engine.
