hey guys i have a 93 f150 i6 2wd. im wanting a locker in the rear and im wondering whiuch trucks have a lsd. are all the f150s in that year range the same axle, does it vary from different engines. pretty much which truck/trucks do i need to look for that will be a bolt up and go that have a locker/lsd. thanks for the help

 

All 1/2 ton trucks of this vintage have the same 8.8 rear axle but there are no factory lockers just the clutch type limited slip, look for an L between the 1st and 3rd digits on the axle tag(3L55) or the letter H in the axle code on the drivers door pillar (H5) for example.

 

If you are wanting a locker for cheap, look into the "lunchbox" lockers that are available for the 8.8.

 

well this is bringing up an old thread but i, going to buy a powertrax locker and need to be sure of how many splines i have in my axle the axle code on the door sticker is 18 but just wanted to see if there was any way to make sure of this. truck is a 93 f150 4.9 mazda 5speed 2wd.

 

1/2 trucks use a 31 spline axle.

 

31spline axle.

 

the website is also showing a 3/4 shaft and a 7/8 shaft whiuch one do i have thanks for the help

 

Are you happy with the 3.08:1 gearing in your truck? I've never driven one with a 3.08.

 

no i hate the 308 it gets really good mialage but i want to get 355 and 31s give it more torque and still try to keep my milage but thats later, i plan on getting a zf5 so ill regear when i do that

im looking at rocky roads web site and they dont haave those part numbers is there any way to tell what i have i dont want to order the wrong one

correction i found those but im looking at getting the lockright lockers not the no slip. part # 1821 and 1822. both 8.8 31spline one is 3/4 inch shaft and the other is 7/8 inch shaft

You need the 1822 which is for a 8.8 31 spline 7/8 pinion shaft.

I have a used 1822 Lock Right I used for 6 months in my 88
4.9l 2wd with the Mazda 5 speed. I converted to 4 wd and the donor
truck had 3.55 gears with a Traction Lok rear so I used that since
the 2wd rear had 2.73 gears.
