Engine/Transmission (1998.5 - 2002) gear change

does anyone know if I can take out my
3. 55 gears and install 4. 10's?

Yes you can. I am thinking about doing it soon. I have a 4x4 and the local 4x4 shop says for $1500 they can do it. A buddy who also wants to do it priced the parts at about $600. We have a mutual friend who is a very good mechanic who is going to help us do one of the trucks, then we will do the other.



I am going to do it so I can run bigger tires (295 0r 305) and still have a decent final drive ration (3. 6 or 3. 7). That will keep the rpms up a little more and keep the engine in its happy place.

Just throw a good timing fuel box on and you will have the best of both worlds.

You will be $ ahead and still have the milage and topend with the 355's.

The only reason to switch would be monster rubber if that's what you're up to.
