Noah Kirk Posted December 1, 2014 Share Posted December 1, 2014 So i am stuck between a rock and a hard place here. Should i buy a dana 35 with 3.55 to match the front for 75 dollars, or should i buy an 86 dana 30 with 4.10 to match the rear for 250? 89 mj ax15 stock height and wheels, planning on hoing 4.5 and 33s. Or should i buy an 8.8 for 250 with 3.55 if i can even find one. Link to comment Share on other sites More sharing options...
mnkyboy Posted December 1, 2014 Share Posted December 1, 2014 I would go with the 4.10s Link to comment Share on other sites More sharing options...

Incommando Posted December 1, 2014 Share Posted December 1, 2014 4.10's. If you have a D35 now you may well end up upgrading it in the future with a stroker and 33's anyway so why spend twice? Link to comment Share on other sites More sharing options...

What gears do you currently have in both axles? If it is a 4.0 and things haven't changed it should be 3.07 gears with a 5-spd IIRC. Auto would be 3.55. 4cyl would be 4.10. If things are still original. A little info about your truck would help, too If you are going with a stroker and 33's and you have a D35 rear now I would just go ahead and upgrade. D35's do not have a reputation for strength. If your front is 3.55 then a later Explorer 8.8 would be the way to go IMHO. A cheaper option would be a later XJ 8.25 in 3.55. If you have a 4.10 then that ratio was also fairly common in the Explorer 8.8. Link to comment Share on other sites More sharing options...
mnkyboy Posted December 1, 2014 Share Posted December 1, 2014 Its too bad I got rid of my last set of 4.10s, I'm not too far from you. Link to comment Share on other sites More sharing options...
Noah Kirk Posted December 1, 2014 Author Share Posted December 1, 2014 Truck used to be a 4 banger 2wd. And previous owner swapped in a 4.0 and made it 4x4. So dana 30 is 3.55 and dana 35 is 4.10. Link to comment Share on other sites More sharing options...
Incommando Posted December 1, 2014 Share Posted December 1, 2014 I would match the front with a good rear either 8.25 or 8.8 then. That looks like the cheapest option. That matches the ratio and gets rid of the D35. I paid < $100 for a good 29 spline 3.55 here 8.25. Hopefully the market is the same there. I use 3.55's with a 4.0 and 32's and it might not be optimal for either on-road or off-road but it does both just fine. Link to comment Share on other sites More sharing options...
Pete M Posted December 1, 2014 Share Posted December 1, 2014 explorer 8.8s can be found with 4.10s too, so that'll allow for upgrading the rear later on. Link to comment Share on other sites More sharing options...

Noah Kirk Posted December 1, 2014 Author Share Posted December 1, 2014 As of now I'm getting the 4.10 dana 30 and upgrading to an 8.8 later. Is there a huge diwn grade between an 89 dana 30 and a 86 dana 30? Link to comment Share on other sites More sharing options...
mnkyboy Posted December 1, 2014 Share Posted December 1, 2014 Not really, with either one your going to want to eventually do a shaft up grade though. Link to comment Share on other sites More sharing options...
Noah Kirk Posted December 1, 2014 Author Share Posted December 1, 2014 With what i could sell my old axle for it will overall cost me about 150 Link to comment Share on other sites More sharing options...
mnkyboy Posted December 1, 2014 Share Posted December 1, 2014 Your probably going to have a hard time selling a CAD D30, alot of people just give them away around here. It may be of more value to keep the shafts out of it as spares. Link to comment Share on other sites More sharing options...
Noah Kirk Posted December 1, 2014 Author Share Posted December 1, 2014 So just take the shafts out of it and junk it or sell for 25? Link to comment Share on other sites More sharing options...
mnkyboy Posted December 1, 2014 Share Posted December 1, 2014 Basically. Unless the truck has had a non CAD axle put in it, then it may be worth selling or could be an axle upgrade for the 86 axle. Link to comment Share on other sites More sharing options...
Eagle Posted December 1, 2014 Share Posted December 1, 2014 I would go with the 4.10s Me too. 3.73s with 31x10.50-15 tires is exactly the same final drive ratio as a stock automatic on 225/75-15 tires. IMHO 4.10s is about optimum for 31" tires. I wouldn't even consider running 33s with 3.55 gears. Link to comment Share on other sites More sharing options...
