GEARING ON MY 4X4
Can anyone help, I have an 1985 blazer 4x4. it had an overdrive trans
in it with a np203 tranfer case and 3.08-1 gears. Now it has a t350 trans and np208 tranfer case. I have lifted it built the engine up with more power. I am going to put 37 or 38 inch tires on it, all of the charts say that i should put 5.28 or 5.71 gears in it for more power over stock are they correct or is there a better way to find out what should be in it. Can you help me. thanks |

Can you help me. thanks Based on your current level of performance, a set of 4.88’s and 37’s or 38’s would give you better performance now than with your current set. You are going to be running into axle strength limitations with 37 or 38’s if you keep stock axles. Give all of this I would say 4.88 or maybe 5.13’s. I would strongly recommand that you find a 14 bolt 9.5 inch semifloating rear axle (not 10.5 full floater) for your blazer as they came with 6 lug hubs to in some truck models and it is about as strong as a Dana 60 but it is limited to a max ratio of 4.88 which would work for you anyway. Another nice thing about the 9.5 is the wide selection of lockers avalible for it automatic and selectable and even the stock posi unit is a lot stronger than one that comes in a 10 bolt rear axle. It is a very wise upgrade for your truck since you plan to run big rubber and the 9.5 will handle 38’s without any problem too. -- Posted using the http://www.autoforumz.com interface, at author's request Articles individually checked for conformance to usenet standards Topic URL: http://www.autoforumz.com/4X4-GEARIN...ict124645.html Visit Topic URL to contact author (reg. req'd).
