SunCoast's Category 2 48RE rebuild kit includes everything necessary to rebuild the transmission in 2003-2007 Dodge Ram Diesels. While the 48RE was designed to support the power of the 5.9L in the past, this kit is a base rebuild kit for customers seeking improvement over the stock unit along with improvements to the band, band actuation, servos, accumulator piston, torque converter and input shaft. With a power rating of 500HP, the addition of a billet intermediate servo, billet band anchor and billet band strut address the common shortcomings of the 48RE transmission. The kit also comes with a new billet blueprinted 4.4 band lever and the included thrust washer kit also contains selections for setting endplay.
SunCoast includes their Category 1 Triple Disc Billet Torque Converter with a 2,000RPM stall speed. The torque converter is lined with carbon graphite clutch material and equipped with a precision CNC machined forged billet apply piston to ensure no deflection occurs. This is an upgrade from the single disc billet converter that comes in their entry level kit. The other great addition is SunCoast's Billet One Piece Input Shaft. The shaft is made from 300 maraging steel and is then heat treated and stress relieved to handle the additional demands of higher torque and stress loads. The shaft is precision ground to make it a true drop-in replacement.
