The factory rear main seal housing cover was not exactly built with big power in mind.The SPE Motorsport billet rear cover gives Coyote and 5.2 owners a stronger solution with CNC-machined 6061 T6 billet construction and a Viton O-ring seal.Important on high horsepower builds where block flex, sealing issues, and rear-cover movement can turn into oil leaks or bigger headaches. It fits stock and aftermarket crankshafts and accepts factory crank trigger sensors.
