F-150 Axle Help

[Boggin]

My dad got a 03 F-150, he dont know what the axle is, cause he was thinkin about gettin a 4wd, but i mentioned a locker, or do you think hes better off with a extreme traction system.....what do you say hes got?

edit: the code on the door is 19?

Can't tell you what gears or if it has a limited slip, but it is an 8.8 with 31 spline axle shafts (it is the same as in the Explorer, only wider and with the 5x5.5" wheel bolt pattern)

k thanks,
so when im lookin for a locker or traction system,
what do i go by?
the axle, or the gears or what?
Also what brand do you recommend

 

[mjonesjr]

You need to go by axle type (8.8) and axle splines (31 spline). I recommend the Detroit lockers.

ok thanks alot, so you would rather a locker than extreme traction system?
i seen a thread about what was best, and most people said extreme traction.

[mjonesjr]

what are the uses of the truck going to be?

 

[Boggin]

also what do you guys think would be the cheapest?

 

[90rangersuper]

the regulat lockrite locker is about 300, the no slip is 400(rough cost), also code 19 Conventional non-Positraction Differential with 3.55 gears

Just for in the winter and since we have ALOT of snow here, and he may go thru a LITTLE bit of mud, just to try it out

 

[90rangersuper]

both will be fine, the no slip you will not hear the ratcheting sound, that is basically what i have learned between the both

 

[mjonesjr]

The "extreme traction" you are refering to is a full locker (ie Detroit that replaces the entire diff). You will be hard pressed to find a lunch box locker that replaces the limited slip diff in the axle in the F-150. To get a lunch box locker, you will have to get an open diff and install it in it.

Get yourself a Detroit that replaces the entire diff. They are more expensive, but they are the absolute best full lockers on the planet.

Just like any other locker, they will release when you are turning to allow the outter tire to spin faster than the inner tire.

ok thanks, and is the locker making the sound constantly or just when its locking a wheel that wouldnt normally be locking
