[QUOTE="qzillanut, post: 1513293, member: 10675"] Another reason is that when sled pulling you run low range. The lower axle and transfer case ratio’s help to reduce the torque output on the rear output shaft of the trans. It’s really not facing anymore torque when pulling a sled in third gear than it is in high range pulling a trailer. I have built pulling trucks for years. We have successfully used bone stock old school 3 speed manual transmissions behind 1000+ hp pro stock head gas engines running down the track at 9000+ rpm. With profab transfer cases and 6.20:1 axle ratios you pull them in 3rd which is direct. The trans only has to deal with the peak torque of the engine in direct. We no longer use the 3 speeds as the 1 1/16 input shaft will eventually fail. But we are talking about 1000+ hp trucks pulling many times a weekend chasing a points series. [/QUOTE]
