4L80 / TH400 Maraging Steel Intermediate Shaft

Made from MARAGING Steel which has a 20% stronger yield point than 300M.

TCS has eliminated the common failure points of the OEM design by eliminating the undercuts behind the ring gear and clutch hub splines. The sharp edges and reduced shaft diameter at these undercuts make the OEM versions susceptible to stress fracturing.

Oil holes have been relocated to the bushing surfaces and one added for the planet assembly.
