SunCoast 35 Spline Sonnax Oversized Shaft Kit 94-07 Dodge Ram 5.9L Cummins
Description
Is your transmission tough enough to take the torque and horsepower your Cummins can dish out? If you are hauling heavy loads or put in some extra aftermarket upgrades into your truck you could get input shaft spline twist or breakage! Get a reliable solution to this with the Sonnax Oversized Shaft Kit. When compared to 300M 23-spline shafts, these 35 spline shafts are 35% stronger where it counts: the spline portion and sealing ring/hole. Critical places where input shaft failure could be dire for your entire driveshaft. Through-holes and cross-holes are designed for optimized converter function so you can be sure that not only is it tough but it keeps OE oil flow areas. Making a perfect union of increased capacity and durability. Whether making a high-performance build, sled pulling, or just towing the boat down to the lake, make sure your truck is ready with Suncoast.
NOTE: Requires a 35-spline torque converter that is sold separately.
