Small case, 3.73 LSDifferential ?

[Simon S]

Here’s the deal – I think too much.
I have a small case 4.10 LSD.
I like that it’s limited slip, and that it’s a small case (less weight). (less weight = good)

Is there a supplier somewhere that provides a 3.73 ring/pinion set (three parts?) that can be swapped into a small case and retain limited slip?

Not concerned so much with power handling due to 4-cylinder – more interested in optimal highway mileage and low weight.

You can find a 3.64 small case diff in the US but I've never seen one with an LSD inside. Supposedly they exist.

Its weight low to the ground and in the rear where the car could use a little extra weight, so its not like its really in a bad place. It would be much cheaper and easier to just buy a 3.73 LSD than to try to rebuild yours, and I really doubt you could notice the difference in weight from inside the car.

Yeah - you're right. It would be a lot of trouble for a negligible difference.
