Merle Coggins Posted August 13, 2008 Report Share Posted August 13, 2008 I'll make a sceintific wild a$$ guess that it's a 1 ton truck (B-3-D)? If that's the case I don't know of many options for you. See if you can check the ratio of your axle gears. I believe the 1 ton's came with 4.10:1 or 4:30something:1. If you have the higher numerical ratio, maybe you can find a 4.10 diff to swap out. This would help some. If you have a 1/2 or 3/4 ton truck you should be able to find a 3.90 or 3.73 diff out of a Dodge or Plymouth car that would fit. The only thing to check is that the axle shaft splines are the same. They made a change in the early 50's to a higher spline count. Your only other options would be to swap out the entire axle with something else more modern, or install an overdrive trans. Otherwise welcome to the forum. Tell us more about you and your truck. Merle Quote Link to comment Share on other sites More sharing options...
james curl Posted August 13, 2008 Report Share Posted August 13, 2008 Check "Opinions wanted" thread in the P15-D24 forum. There is a post with all of the MoPar rear end widths toward the bottom of the thread. Quote Link to comment Share on other sites More sharing options...
