Re: 9 Inch Axel Choices
I have to agree with steve83, in my opinion the 8.8 is a solid axle. It works well with a Bronco because even though the Bronc is a fullsize, it is lighter than most fullsizes, unless you go and add a bunch of super duty bumpers and a huge winch and what not. The 8.8 can take the 4600 pounds give or take of the Bronco and the power of a 351, and some decently sized tires 35's or so. As long as you are sane with the throttle, should hold up fine. Going to a 460 or a built 351? Or maybe 38's, then I would say the 8.8 may be weak for the application. But I would also say in that case, change the front while you are at it. The 8.8 is really the same ring diameter as the 12 bolt GM (8.875). It uses 31 splines in the fullsize applications, and those shafts are pretty thick as well. The GM uses 30 splines, and I believe the shafts are slightly smaller. C clip not real good. Anyone have the scoop on the eliminator for this? But strength wise most say stronger than a 44, close to equal to the 9", slightly better than GM 12 bolt, not as strong as dana 60, ford 10.25, or GM 14, but as you say, you will lose a lot of clearance with those axles and are they really needed? GM puts 12 bolts under subruban 1/2 tons. Now in my opinion modifying/using that setup is pushing it. There are also aftermarket forged axles for about $100 for the 8.8.
