The Sun Coast 5R-BISAR is a billet Aeromet input shaft for an E4OD, a 4R100, and a 5R110W. It is the step up from the 300M shaft, 5R-BIS. The transmission has to come apart to install it.

Sun Coast heat-treats it and precision-grinds it. The spline is 30/31. It is rated around 2,000 lb-ft. Aeromet resists a shear break from a hard hit or wheel hop, and it resists the fatigue break that shows up on a tow truck. The output shaft and the pump are not included.

It fits 1994–2010 Powerstroke trucks with an E4OD, 4R100, or 5R110W.

The 300M shaft is enough for most builds. This one is for a truck that already broke a shaft, or one that sees shock loads. Match the shaft you pull.
