alright I'm new into looking at the lockers and regearing i have a 2002 f150 fx4
with a open diff so i want to get a auto locker I've found one that matches the 9.75 ratio 34 spline but could someone shed some light and tell me what is need to regear and have this done I'm wanting to go to 37 later in the future and i want to make sure i have everything ready when i make the switch

thanks guys

 

4.88's for gears front and rear. I'm running Detriot True Tracs front and rear. I may be swithcing to a lunchbos locker upe front, along with a Detriot Locker in the rear..

 

i guess what I'm asking is what all do i need to buy when i regear everything like differential cover and such is it needed cause what i plan to do is buy all the parts and take it to a shop to get everything installed so that i don't have to worry about it and i was looking a auto locker

How would compare the trutrac to the full Detroit mechanical locker?

 

The true trac is a limited slip that doesnt use clutches. it can still slip especially off road.

 

I know what it functions as, I was looking for more of a capability comparison between stock LS, true trac, and mechanical locker

 

It is excellent as it what it does. I have found that it is great on the street as well as off road. But it does leave a lot to be desired when you start getting off camber when off road. If offroad performance is what your looking for then a mechanical locker would be best.

Are you running different tire size?

Also what's your RPM at say 80mph?

 

With 37's and 4.88's would be very close to stock rpms @ 80. My truck has 33's and 4.10's. My truck wont ever be any bigger. I have a mud toy and that is what its job it for to be big and loud..
