hi guys , i have a 95 cc/lb 4x4 just swaped to a sd pcm 4r100 and sd tcase. instead of modifying my rear drive shaft to fit the sd tcase i was thinking of upgrading to the 1410 rear pinnion yoke and running a 1 piece driveshaft . i already have a sd front driveshaft but the rear i dont have. i would think a 1 piece would be stronger for pulling and higher hp. my truck is between 450-500 hp guestimate with my setup. i do pull up to 15k. i would runa drive shaft loop also if i went this route. if anyone has any info please share this with me i have wonderd why these trucks run carrier bearing in the first place, is it because of angles of suspension and driveline to keep the geometry right? harmonics in the line? thanks for any info.
