Friends,

Is it possible to convert from a regular 3.55 rear-end to a limited slip w/o changing axles? If so how expensive is it and how difficult is it if I should decide to tackle this project myself?

Thanks,

I'm interested too !!

 

The axles don't change, the carrier does. If you have an 8.8, you need a 31-slpine Traction-Lok carrier, Ford Motorsport P/N M-4204-F318 ($250 at Summit slightly more at Jeg's), an install kit ($80-120) some gear lube and a 4 oz. tube of friction modifier, Ford Motorsport P/N M-19546-A. If you want to change ratios, this is the time to do it, add in another $180 for the ring and pinion.

This isn't a home install for most people, especially if you've never done one and don't have the tooling. Figure on paying a shop $200-300 labor plus a markup on the parts.

 

StrangeRanger is right. But, you don't have to use the Ford Trackion-Lok carrier. There are a lot of aftermarket ones that will work too.

 

If you have not done this before or don't have a good mechanic as a friend, don't do it yourself, just take it in to a good mechanic. With this type of investment you need an expert to set up the ring and pinion clearance, select proper shims, and examine seals/races/bearings/etc. I agree with StrangeRanger about the gear change now. There are 5 or so good aftermarket units. It does become a do it yourself job if you buy a used whole rear end, they are everywhere. Richmond makes a video on "how to change your ring and pinion". Summit carries this as well as the complete parts kits.
