I don’t care what anyone says bigger is better. Especially when it comes to your transmission shafts! Don’t get caught with your pants down at the track because your shaft left you unsatisfied. Factory dodge 23 spline outputs are good to about 650hp, billet shafts about 800hp, fat 29 spline outputs are even higher. Upgrade to a 29spline with matching transfer-case input to your transmission build today! Also pictured twisted Allison 1000 shaft.
