| Over/under transfer case????
Looking for thoughts and opinions for the RC4wd over/under transfer case. I知 considering one for a Frankenstein build I知 doing. Will be using parts from VS4-10, axial and Rc4wd. I致e used the hammer T-Case before but have no experience with the over/under. Just wondering about quality and reliability. Sent from my iPhone using Tapatalk |

I've been also considering it for my G2, but as you know, it needs 2 parts, the mount with the battery tray and the transfer case itself, which cost more than 120 pounds altogether. Its half the price of a brand new Enduro kit....Thats abusive.

Now this won't work in all applications & certainly isn't a drop in to a RC4WD truck but for custom building where you're dealing with a DIY cross member you can achieve the exact same OD from a stock RC4WD T/case without paying the extra for their OD version, just got to turn it over & re-arrange where you drive in & where you attache the drive shafts. Stock in top pic Alternative in lower Saw someone else do it & it worked out well in my TF2 Blazer, turns the AtlasII T/case right way up for starters & swaps front drvie shaft off to the right drop to suit the K44 axle |

I bought the RC4WD OD/UD transfer case, just need to go through it and then install to my TF2. Going with the 17T / 19T combo for 27%. |

You've got me having second thoughts now about my OD ratio, somehow when I calc'd it before it didn't seem that high compared to say OD/UD in an scx10 but looking again 47%OD is quite a bit & is quite different to the Axial ratios 28% OD/UD (13% UD/STD or 13.6% STD/OD for those playing at home) |
