ive wanting to do a gear change and my 94 formula has 3.23 and i want to put 3.73 can i just change the gears with the same carrier or will i have to get a different carrier too? and i also hear something about a pinion bearing?

 

Your carrier is a 3 series so your good there with the 3.73s. Many people use Motive gears, set up correctly their pretty quite. A full install kit will include a new pinion bearing if you think you need it. If not, you can use the cheaper install kit.

 

so could i put 3.42 on the carrier i already have no problem without changing anything?

 

Yes, you could do that, too. Don't forget computer programming.
