The SPE Motorsport 6.7L Powerstroke 4R100 Rear Cover is a CNC-machined billet aluminum direct-fit replacement for the factory rear cover that opens the door to one of the most respected transmission combinations in the diesel world — the 6.7L Powerstroke engine paired with a Ford 4R100 transmission. Proven first in the SPE V1 Rail truck, this cover lets builders and competitors combine the 6.7L's massive power potential with the legendary strength and simplicity of the 4R100.
Snyder Performance Engineering designed this rear cover to bolt up to the factory-style gasket and rear main seal (both included), with a modular Ford 4R100 bolt pattern on the transmission side. The crankshaft position sensor, starter, and dipstick tube all bolt directly to it exactly as they would to the factory cover — no modification, no relocation. Everything needed to do the swap cleanly comes in one kit.
