I have a pair of 60's. Unfortunately the gear raios are different. The front is 3.54's and the rears is 4.10's. My buddy has a rear 60 with 4.10's in it. Can I put these gears in the front?

Yes

I thought so but just wanted to be sure. I want to get my truck going again and need to do it as cheap as possible. Thanks

. I have the exact opposite problem you have because I just had to replace my D70 rear and could only find a 3.54, my D60 front is still 4.10. Turns out the cummins didn't really lose any grunt and I can actually drive on the highway now :smokin: (2800 rpm redline here)I don't do any extreme rock crawling, so I'm going to swap my front gears to match.

If the D60 3.54's you take out are in good shape, I need a set. PM me with what you're asking or if you want an even swap for a set of used 4.10's. It would save us both some work.
