D70 or 14bff?

[blazen91]

On the duelly I bought, it has a d70 instead of a 14bff. It already has 4.56's which is the gears I want. Do you all think I should keep the d70 and put a Detroit in it at the cost of $550, or sell it and build a 14bff. It will be in a 90% trail rig. The other 10% will be my wife showing off that her Blazer will be tougher than mine!!

I think I would go with a 14B FF just because parts would be easer to find.

By the time you buy a locker for the D70 and pay to have it installed (new r/p setup), you could buy a C14FF (with 4.56) and a locker (which you can install in your driveway). The strength is comparable and I don't think the D70 has any advantage over a C14FF. Hmm, do I remember the D70 having like 1/4-1/2" more clearance? Not sure...

So how much do you all think I can sell the d70 for?

Me, I have no idea what it's worth. I have never priced a D70. I would think it would easily cover the cost of a C14FF which can be found in 4.56 for $100-$400. You might even get enough to cover the cost of a Detroit Locker ($395??). I would call around to the local truck wrecking yards and act like you shopping for one. Get a few prices and then knock off about 20% (truck yards are almost always over priced IMHO).

Depends on what you can sell it for.... If you can make money on it, then sell it and get a 14FF. If not, then Get a Detroit for the 70..

Hey Mike,

The only advantage I see to the D70 is that you can buy a ARB Locker for it. But if it is 95% trail rig a Detroit will do great for a lot less cash.

See Ya,

That dually 70 is probably narrower than a single wheeled 70 or 14B FF. Measure it before you decide to use it.

I dont see how an ARB would be an advantage. In a rear axle you want as much strength as you can get. The Detroit is the best way to do that.

Oh yeah, sell the 70 and get a 14 bolt.
