    Does anybody know if Wagoner Machine's 3:1 gears for the 203 will "bolt in" a 203 in a single case setup? Or is this only available for multi case setups? What machine work is needed? Anybody used these 3:1 gears? I emailed them but was wondering what experience others have of this. /forums/images/graemlins/ears.gif /forums/images/graemlins/ears.gif

    From talking to them,
    They have to machine the case for gear clearance.
    Yes you can use it seperately.
    I havent gotten it yet, but plan on doing it in the future.
    I still have to put my truck together.

    Let us know if you do go with it.

    Greg72 has a set from them, like said above, the case needs to be clearanced for them to fit but you don't have to do a doubler to use them.

    What kind of cost is there for the gears and also for the machining?

    When I was talking to them about it a couple months ago I think it was right around $1000 plush shipping the case.

    A little pricy but worth it in my book.

    Now if I can just find me a 205 for the doubler.

    I've looked into the 3:1 kit for my rig...

    You cna use it in any NP203, meaning it isnt just for "doubler" applications.

    After I took a good hard look at what is involved, I'm actually making the 3:1 kits myself. It took alot of time and research to figure out what was needed, but once all is said and done, its fairly easy.

    Wagoner are good guys. I just had them do some spline work for me. The cases defaitly do have to be clearanced, as the larger gear would't fit without cutting a hole in the case.

    I don't think I'm gonna persue this anymore. $1000 plus shipping for 3:1 doesn't seem cost effective.

    dhdescender, how far along is your 3:1 setup, are you planning on selling them?

    $1000 for a 50% increase in gearing isn't cost effective? Have you priced a pair of axle gear swaps? Rarely do you get a 50% improvement with a diff gear swap, plus this is "on demand" which doesn't hurt street economy AND you don't wind up with a toothpick pinion.

    It seems like a good deal to me, too. Even more so if you have dropped a bunch of coin on driveshafts.

    Well, I'm an idiot /forums/images/graemlins/rolleyes.gif /forums/images/graemlins/rolleyes.gif, 3:1 for $1K is a pretty good deal.
    I severly underestimated the cost of other t-cases with close to that gearing(Atlas). I was just looking at 3:1 to put in a 203 I have and putting that behind a 700 i had. But I sold the 700 and don't think I'll be using the 203 anytime soon.
    Thanx for the info guys! /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    How are your skills at welding cast iron?? /forums/images/graemlins/cool.gif

    Once you get the gear clearances you need, there will be a big hole in the side of the case, that will need to be welded up with a new plate.

    Not bad... /forums/images/graemlins/wink.gif
    I'll have to weld my 14bff housing after hogging 2" off-it..
    If the gears are priced to bad...
    I may as well ad a 203 case to the list... /forums/images/graemlins/cool.gif

    I asked about prices in my email to WMS for just the gears if it was a bolt in. They didn't give me prices at all in their reply, just said the case and shaft require machining.

    I'm interested in the price for the gears alone also. If anyone gets a quote for just the gears, please post.

    dhdescender/Kyle, did you mean that you are machining your own gears from scratch?

    Kyle, I'm interested in that Allison converter for TH400...what's the story on that? I'm 6.2 diesel.
    I was going to build my TH400 with a 3:1 first gear...that's only .5:1 improvement over stock, and the planetary is ~$1000 so the 3:1 for 203 case sounds like a bargain...I'd hate to think I'd do both but if the money comes during the build-up, well...

    Eric

    I'm Getting Vancouver Gear (www.vangear.com) To cut me a new set of gears. For now, I'm welding the two together.

    The gears I'm working on are actually about 3.2:1. I'm working on a larger reduction, but I think the NP203 Box is just too restrictive.

    We're not supposed to sell anything over these boards, so if your interested in what I'm doing or want estimates...PM me.

    **PS**

    The Allison 540 converter has a welded steel stator, splines cut from billet (not cast) and full brazed fins. Essentially it's the sh!t. It will work wonderfully behind a diesel, becase thats exactly what it was meant for.
