hey i've got 4.56 gears and i'm thinking about getting a powertrax extreme locker, any reccomendations would be great, and i was just wondering what size spline i have on my 2002 3.0l extended cab ranger, thanks guys.

 

Not sure about the powertrax, but I have never heard anything bad about them.

You have a 28 spline axle, only 31 splines come in FX4 L2's and other vehicles.

 

If you have the money, consider a selectable locker. I have the Auburn ECTED and it's a limited slip until you lock it up. It works GREAT.

 

If you decide on the PowerTrax No-Slip unit, i've got a brand new in the box one for sale!

 

go with 31 spline axlesand I have not herd anything bad about the powertrax.

 

You can only use 31 spline axles if you ALREADY have them lol. You cannot put 31 spline axle shafts in a 28 spline axle housing. The 31 spline axles have bigger bearings and the axle tubes and center housing are actually different.

I changed my 28 spline out for a 31 spline from and FX4 (the entire axle) and it's a very good mod. But if you need more strength, you can also get specially made 28 spline axle shafts that will fit your housing that are stronger.

 

I dont recommend getting the Powertrax Lock-Right. I had one in my rear end for about 8 months, The teeth on the couplers and drivers wore themselves down, and it would constantly slip/grind and jerk the whole truck in all driving conditions. It almost ruined my whole rear end.

Now you guys have heard something bad about powertrax!!!


...but while it was working I loved it, so much traction!

 

In powertraxx's defense you have a Ford 7.5 rear end. that might be a little bit different than an 8.8 unit.

 

thanks guys, so which is it 31 or 28, and now that you mention it im not sure which i have cause im afraid they might have changed it out with the new gears im not sure...anyways thanks again guys

 

you have the 28 spline. they can not swithc out the shafts to 31 plines unless they switched out the WHOLE rear end. you have a 28 spline 8.8...

 

Which is what I've been saying all along, lol. If you ask a question, read and think about all the posts!

Look at your axle tag to be sure. It should be under one of the bolts that holds on the rear cover.

Here's a link to a "decoder" for the information on your axle tag.

Keep in mind you've had a gear change, but the other information is useful.

If your axle tube is 3.25" diameter, it's a 31 spline. The 28 spline is smaller than that.

 

yeah my tag used to say 4 10 88 but since i got the gears changed the tag is not on there anymore, so 28 spline thanks guys.

 

hey tommy, whats up!

are u looking for a locker or limited slip?
