I’m surprised interest didn’t take off, using the Tesla drive longitudinally makes so much sense My last project used a full rear suspension/drive with a ldu. Since it was a custom chassis I was able work with the wide track of the Tesla S. I’m in planning stages for a conversion and that’s why I’m thinking about the longitudinal angle.
Your new build looks interesting: details?
Here’s my last one.

So Felton has a solution to allow use of the ldu longitudinally. Tesla Large Drive Unit Driveshaft Adapter Kit. The problem is that the gear reduction in the ldu would, in combination of the rear differential, result in a motor that spun pretty fast at relatively low speeds (great for rock climbing). And the top speed would be limited. Felton does offer another solution to change the ldu gear reduction from 9.xx:1 to 4:1. That would still reduce the overall top end depending, of course, on the particular differential used. In my particular case the differential is 2.88:1 so the overall gear reduction would be 11.52:1. Steeper than the ldu but manageable for most uses.

Winters has a QC with a 1.20 ratio, for a leaf spring rear old car might be workable. likely some $$$ but maybe that ring gear qc set could be used in one of the other formats.

I'm wondering if an electric motor would strip/break those with the torque they put out at low speed?

was just food for thought, my understanding with QC is the thru shaft is the weak link. if I were doing an on axis layout it seems like a custom housing and a couple spur gears would do it if I could figure out how the mask the noise. I was also looking at stealing the planetary from an auto. But I lost interest since I decided to go another path

Hello everyone, I have C5 corvette complete front and rear suspension assemblies, and just purchased a Tesla rear SDU. I also have a CNC mill and a lathe and experience in metal fabrication. I am interested in modifying my SDU in a similar way that Roadstercycle has shown above, so that i can attach an output shaft to the intermediate gear, and stuff that into my Corvette differential. Before I start ripping the SDU apart to reverse engineer a new billet cover to accommodate an intermediate-gear output shaft, does anyone here have any advice?

@Roadstercycle: do you have any photos or prints/sketches of the cover that you ended up casting? I will end up making something very similar out of billet aluminum, so any head-start you can help me with here would be great!

Take your time and have good measuring tools. Take it apart and look at it and keep looking at it until you have the whole thing designed and built in your head. What steps to do first and what to do last. Don't build yourself into a hole you can't get out of. Think it through.
