Eaton rs 402

If you get the same number of bolts in the housing they fit. You just have to grind out a notch in the banjo to fit the locker like the old one has.

 

And don't forget a new axle shaft on the fork side...

 

Yes that is a 2 speed, R is rear tandem, T is dual range 40 means from a 40,000 pound set and 2 is the design level meaning it is 2nd generation.

If you want a RS402 in a locker version you are looking for a RD402, the D means single reduction locking where your current rear is S for single reduction limited slip. Hope this helps.

 

Wholly crap it's a 4.33, it's gunna crawl

 

What kind of work do you do that makes you wanna roll with 4:33's? Pretty stout set-up, but def. not the best for highway running.

 

That looks like a single or a rear rear to me from the pictures. No extra gear case or anything. No way its a two range rear Im thinking of. That looks like one of those half split rears you split in every gear. NOT GOOD.

 

Did you ever find a 402 diff with a locker, or exactly what the model number is? Same boat here, 94 Pete with 402's no lockers
