Axles with Ratios Comparable to K44?

[JonFoster]

I've got a RC4WD K44 for an upcoming build. I got it mainly for looks over performance and/or compatibility because it looks similar to a Ford 8.8" rear end. However, now that I've been doing some research, it seems to be a rather uncommon ratio of 2.67:1 (RC4WD doesn't list ring and pinion tooth count, and I haven't pulled the cover to count). Admittedly, I've only been looking at RC4WD and Axial axle sets trying to get something to match for the front.

My question is, are there any other scale axles with the same or maybe slightly overdriven gear ratios out there? I'm looking for a modular Dana 44 style axle to build out into a Ford TTB. Many thanks in advance.

The Gmade GA44 uses 3:1 (33/11)

I think that works out to about 12% overdrive.

Thanks! I'll look into those!


So the K44 front axle just got a restock. I'm not sure I want to hack up a metal axle just for the diff or not. I could also rob the knuckles and axle shafts, too.

The Yota axles have the same gear set...15/40. There's also a Helical R&P set, with the same ratio...12/32 = 2.67.

There was a machined K44 that had a 3:1 ratio but that is long since discontinued and can be distinguished in the front by having RED CVD axles, as apposed to, the cast GOLD CVD's. I actually own a set of both of these and tried to put 3:1 gears into the cast housing, without success.

Be careful when using other R&P sets...they may have the same ratio but may be larger in size and may not fit the housing. I believe any of the Yota sets should fit the K44 housing.
