rippledabs · **Question about 1.6 Diff Compatibility**

I remember reading somewhere that the stub stafts of the viscous diff are different from the open diff, but I'm not sure if anything else is different.

Will the viscious diff + Stub shafts bolt up to the axles and drive shaft from the open diff car?

If memory serves, the open actually has 1 long and 1 short stub. The lsd has 2 medium length stubs. I never tried to mis-match, but I suspect that there is a reason why the stubs are all different lengths.

The axles themselves are all the same. The difference is in how far the stub goes into the pumpkin.

Thanks for the info, Ben.

Do you remember if the driveshafts are the same too?

yeah I'm pretty sure they are

The VLSD has one big and on little. The open has two the same size. If you need a set I have a pair of each, from my collection of blown up diffs. And to think I'm not even boosted yet.

Yep. A complete assembly of VLSD diff and stubs axles can be swapped into a non-VLSD car using the original CV axles and propshaft, and vise versa.

thanks for the info.

I just trying to sell my old viscous diff, and trying to answer people's questions.

btw, $150 shipped for vlsd in classified section!!

I just bought my second one for less than $100.

VLSD at this point is no better than an open, and must people understand that.
