Guys, build the OD section to 2006 diesel specs and you can drag race that thing with the OD on. Think about it for a minute, the 47/48 diesel trucks are towing 20,000 lbs plus in OD these days. Just go get the thin snap ring, the OD retainer plate and ditch the wave spring and you get an extra clutch and steel in there. Also, if I’m not mistaking the diesel spring is heavier than the gas job.
