    Just wondering if the 4:1 241 from a heep Rubicon would work in my Blazer? That would be perfect. I'm not extreme enough for a doubler, nor rich enough. Thoughts anybody?

    Its a round pattern, so check your adaptor, and IIRC 23 spline input. Also pricy. JB conversions can fix the input and they were selling them at one point.

    yeah i see roctracs selling for 800-1200.

    by the time you convert it, you could've had a doubler.

    or a klune-v.

    yeah, i doubt this is a "cheap" alternative to a doubler. Adapters and different spline counts... not good!

    As far as being "not extreme enough" for a doubler... the rocktrac has the same low gear as a doubler would. If you ain't "extreme" enough for 4x gear reduction.... stick with a standard 2.7-ish:1 geared 241. Lot cheaper that way.

    I've been thinking about it too. I just need to have somebody loan me a case to tear apart and see if the input shaft will interchange with a GM one. Sorta like being able to put a 32 spline one in place of a 27 like I did when converting to a th400.

    Isn't there something called a LoMax 205 that would do the job for about the same price?

    If the lomax 205 were available yet... even then isn't it only 3:1? .3 more then a stock 241...

    Moreover, How about the SYE that the NV241J uses? Anyone check into prices to convert to a fixed yoke using Rubicon parts? :thinking:

    I don't know the priced but from all I have read you can swap all the rubi 241 parts with regular 241s. I know that atleast one guy on PBB has a Rubi 241 behind a 27? spline 700r4

    I just dont think I need all those gearing options and sticks that come with the doubler. Even a weekend warrior like me would always benefit from 4:1! I kinda figured the adaptors and all that would run up a prohibitive cost, I was also wondering if we could just swap guts, you know?
