Solid 37-Spline Input Shaft Kit 47/48RE Transmission/Converter - Dodge 1994-2007

The solid input shaft from Santjer Performance is larger, stronger, and without the inherent lube port stress concentration weakness of the stock shaft design. It's able to deliver these benefits without compromising fluid transfer rate; an issue common to larger shafts that reduce port diameters for slight strength increases. Direct hub spline length has also been increased for additional clutch capacity. Torsion tested in excess of 4000 ft-lbs without failure, the solid input shaft uses a proprietary heat treatment and ultra-high strength VAR alloy. Now available in TrackMaster Transmissions, with Solid Shaft ready Hi5 or ProForce 3D torque converters.
