I've heard 3.73s are the lowest(numericly) that I can go. I want something around a 3.42. Is this not possible?

chicane

The lowest numerically ?? Uhm... no. Specifically with a Strange Spool ?? Yes.

But... you can always have Mark Williams cut you a spool for the difference in flange height. In fact, he may still have one or two still on the shelf (just confirmed with Bret). The only requirement that you will have is that you will have to run a 30 or 35 (no 33) spline Mark Williams axle. The reason being for that is the difference in spline pressure angle. Strange and Moser use a 30* pressure angle whereas Williams uses a stronger 45* pressure angle.

Even if he had to cut you a single unit... it would run you about $600.

FYI, a current list of available 12 bolt gears:

3.08
3.42
3.55 (R)
3.73
3.90
4.10
4.30
4.56
4.88
5.14
5.38
5.57
6.00

Thanks for the info but I didn't mean it's not possible at all, I mean with what I have to work with. I'm not looking to spend a lot more than I already have on this rear. I have a strange 12 bolt, 33 spline axles and its spooled. I just want to change gears, when I changed them in my 10 bolt it was around $500 out the door. That's all I want to spend for now. Are there any options out there?

chicane

Well... with the Strange axles... you are pretty much limited to a 3.73. Nothing really left for options other than what I posted earlier.

I feel your pain. I have had a few clients over the years do exactly what you have done, gone from a NA build to a forced induction... and there is really no other recourse but to change more parts.

I wonder how much everything will add up to if I choose to just go ahead and go with the 3.42s. The only extra parts I would need are the axles? Man I hate redoing things

chicane

Yeah... but your going to a far superior axle, with the gears you want to run. That is the payoff... unfortunately, cost is relative. Dont think of it as 're-doing' something... think of it as an upgrade, in strenth and saftey. If its worth doing, its worth doing it right.

Worst case... new axles and bearings, new spool and gears.

It would be cool if the bearings would cross (Strange to Williams)... then all you would need would be the axles, spool and gears... sans the new housing ends.

If I'm not mistaken you can call Strange and have them custom build you the gear your looking for. I have 4.10's in my Dana60 because it didn't come with a 4.30 gear option. However they did tell me they could build a 4.30 gear set for the rear if I wanted to wait 4 more weeks. Didn't have the time at the time, but I'm going to call them and have the 4.30's built.

chicane

... yeah, at a cost that I wouldnt even want to repeat.

Same $ as any gear they shelf stock. They told me it would not be any difference in price. They just wanted 4 more weeks and I couldn't wait any longer.

chicane

Ah... they are just waiting for a production run...

That makes a little more sense. I do know however that an actual custom gear set runs about $12000 to 15000... for a single set.

maybe go up in tire size.... might be cheaper and would certainly hook better, just a matter of if it will fit. And doing whatever is needed to make it fit now, will just save ya time later down the road.

Yeah, I'm already up to a 28" tire and that's as big as I want to go, no cutting bumper, my cars a show car to Not really, but I want it to look like it could be.

I just decided to go with the 3.73's, I liked the way the 4.11s drove so the 3.73s should be close but hopefully make it through the 1/4.

I hear ya my car still goes to a show or 2 every now and then.... but not for much longer.. the risk of driving it just isn't worth it anymore. 3.73 should get ya where you want to be gear wise, and if not, there's always a little custom bumper cover notch/redo you can do, mod the tunnel to lower the back some, and put a 30 inch tire on it. That would look and definately get ya to more MPH then the car will run.
