I just asked them. No, they do not have anything that fits the Tremor or any Ranger shaft that uses more than 4 bolts to attach at the rear axle. (I've seem a couple non-tremors use this design).

Hey everyone, I'm back with news! A lot of people have asked about an aluminum shaft. I've always said it's not possible, because it didn't used to be possible. However, another company, Knoxville Driveline, has developed the required parts and the complete drive shaft. I'm personally running...

I realized that my last post was one about still actively trying to develop a shaft for this vehicle and wanted to update everyone. I got a stock pinion flange, hoping that it would be a common spline size that could just be swapped with a more standard flange or yoke. I don't think it can be...

Hey everyone, here's where the Tremor Drive Shaft development process has been: I made 1 or 2 custom adapters for people to test the performance of a one piece shaft in the Tremor. Good results so far. But I've personally had to machine the adapters using a manual lathe and drill press which...

Technically it is a Stella, a reproduction of the 70s era Vespa. I forgot that I put that in my bio, I was mostly being a bit tongue in cheek. I live in a world of big trucks, big jeeps, big everything. As a sort of vacation from the world of trucks and Jeeps that I've been a part of for most of...

Hey all, @Greywhale here is the first test pilot for the one-piece rear Tremor shaft. I know, I know, it's really made of many different pieces, but you all understand what that means, it is a single shaft that eliminates the carrier bearing. As has been reported, the first prototype is working...

Because "should fit" and "does fit" are not always the same thing. I think we've all had the experience of going to the auto parts store and getting a part that is listed as the correct fit for our vehicle but it doesn't fit or doesn't fit well. Taking a couple minutes to scoot under your truck...

It is impossible to do aluminum on these shafts. This is because the slip yoke has to be integrated into the drive shaft. the spline stub needs to be steel and the spline stub needs to weld to the tube. Obviously you can't weld a steel spline stub to an aluminum tube. If you look at aluminum...

The length won't really change. Not enough to matter at least. If you're interested in calculating the length change you can do that here https://4xshaft.com/blogs/general-tech-info-articles/driveshaft-length-after-lift. There is a calculator, which I made, at the bottom of the page. It's...

Find me a stock drive shaft and a stock rear pinion flange and we've got a deal. If it's possible at least.

We've got to finish with this can of worms before we open another one.

Yep, @TJC, you have paraphrased me well. I've put the tools out there for people to dig deeper into the "critical speed" thing, so that you don't have to take anyone's word for it, including my own. But while some evidence supports that theoretically go faster than 100 I'm not going to green...

I've read/heard that from a couple people. Which is exactly what I mean when I talk about quality>quantity of results. It makes it feel wrong to consider discontinuing these shafts and taking the "Not my problem, buddy" approach. For the time being at least, we will continue to offer them and we...

I'm happy to hear that the shaft worked well for you. You know something, your post came at a funny coincidental time. Just a few days ago I was talking to a colleague about how some new products are a hit and some are a dud but we just don't know for sure until we bring the product to market. I...

I heard about this one today. Honestly I didn't know that there were 2WD versions of this truck available but will be updating our website for the benefit of other 2WD Ranger owners in the future. I'm sorry for the confusion. To you question of whether or not anyone has a fix for the 2WD trucks...

Oh for sure, costs of materials, labor, shipping, and everything else add up to almost as much money as we take in. Not quite, but almost. Quantifying it as I did was just my way of saying that I've got a lot of other things that require my attention, so please forgive and understand my...

You are very accurate. There's a couple reasons I haven't commented thus far on your calculations. "The defense rests, Your Honor". I feel like I've said everything that needs to be said. All the information is there. I've explained how I have come the my own conclusions and laid out the tools...

I stumbled upon an interesting and funny video today. Not Ranger specific but it is regarding a recall on some other ford shafts. Enjoy.

The surface Speed of the shafts is different because of the different diameters but the RPMs are exactly the same. If you watch the lower shaft and pay attention to every time the white sticker comes around you can see in your peripheral that the sticker on the upper shaft leads it by a quarter...

I think the mystery of the off-centered stock bushings is a simple one to solve. The rubber is soft, barely firm enough to hold the shaft in place in the first place. So if it is just a teeny bit softer or more broken-in in one section, the shaft is going to naturally come to rest off-center...
