    still trying to figure things out on my machine. it is just off road use. 74 blazer frame, 75 3/4 ton axles (dana 44 & 14 bolt 10.5) 4.10 gears 44" boggers 350/350/203. mild cam small stall, all tube body seats 4 Question is it needs more gear 5.13 is tops for the 14 bolt should I go to a different rear end, dana 60 or 70? then I could run 5.88 gears. /forums/images/graemlins/dunno.gif

    You could keep the 14 and get a Doubler.... /forums/images/graemlins/laugh.gif

    i think the dana's might be able to go lower than 5.88's, i thought i've seen 6 something, but then you have gear strength issues, i would definately go as low as possible, and if you have the options, maybe a d70, if its trail only though you dont have to worry about lockers, so maybe a 14FF welded or detroit and a doubler. anyway i dont know if that helped, i'm sure someone else may chime in and correct some of my errors /forums/images/graemlins/whistling.gif /forums/images/graemlins/thumb.gif

    Can;t say I'd want to run that low of a gear though, you'd be winding out big time even with some 44s, and I can't picture there being a whole lot of strength in that many teeth.

    but LOW LOW LOW gears on a D44 isent a good idea espically with 44 BOGGERS you wont have much gear mesh

    didn't even notice that, definetally wouldn't want to run 5.88s on a dana 44 with 44s, heck I wouldn't want to run 2.73s, D44 and 44s.

    I just realized it was a Dana 44 front. Oops...

    I'd be looking for '60 front or a smaller set of tires, or both, in a hurry!

    Go doubler and get a heavier set up on the front. The lower gears 5.whatever and lower have such a small pinion that it can strip easily. That is why 4.56's and 4.10's are so common. The doubler makes up for it.

    yeah, dont look back, and you'll never notice the pieces of your front axle you left on the road. Dana 44 is a model number, and has nothing to do with the size of tire it will support. you wont catch me with anything bigger than a 36 x 12.50 on a 10 bolt or D44. i've heard too many horror stories.
