mopar346 OP Let me tell ya about fat chicks! M Joined: Jul 2007 Posts: 11,836 Florida	I have an 82+/- Ford truck Dana that is going to be cut down and built for a 68 A12 spec Road Runner. I believe it has 35 spline axles and I have been told I should change the side gears to 30 spline. Not a big deal since I will buy axles and go through the unit, but my question is why? Careful, your character's showing!

If it has a good power-lock or track-lock I would use whatever spline the side gears are.If they are 35 spline don't change it to thirty spline unless you need it for the sure-grip you are planning to use.

I already have the parts list from Dr. Diff for axles and housing ends. I wasn't sure if strength was an issue, but frankly it will probably never be heavily tested. Maybe 6-700 hp at most, but not enough chassis to put it down or hook seriously. Careful, your character's showing!

Since you are building from scratch you should use 35 spline stuff since it cost little or no more for axles and 35 spline side gears are relatively cheap for a trac lok or power lok if your's doesn't have them. It's good insurance in case you decide to put some drag slicks on it.

So are ya'll saying the 35s are actually stronger than 30s? My comment about traction is from the fact that I do not plan to build the chassis to hook, ie roll bar or tied subframes. Without the proper chassis it wont transfer well enough to hook hard enough to hold the hp on tires, even slicks, that will fit in stock wheel wells. Careful, your character's showing!

He told me that DANA/SPICER never made a D60 35 spline rearend for any aplication. They did make D 60 35 spline 4x4 "FRONT" axles So for you guys hunting the junkyards for a 35 spline D 60 "REAR" axle, it doesnt exhist.. D 70s do have 35 spline axles... I am truckless..

I pulled one of the axles and counted the splines, maybe I have it backwards but I would bet money I counted 35. Careful, your character's showing!

Worth the extra 150.00 for the special bearings to install it. Never have to worry about breaking a ring gear. You might also look at using the Jeep ends, if you want a factory rear disc brake for less than $100.00. The Ford Explorer uses the same rear brakes as a Jeep Grand Cherokee but with the ford metric bolt pattern. The jeep uses a Timken set 10 which has a 1.562" ID and the 35 spline gears are 1.5" O.D. Just some food for thought. Tim

But if for some reason (wear) I have to change them go with the 30s. Right? Careful, your character's showing!
