Hey guys, how do I know what axle do I have? And how do I know if my truck has diff locks? I'm guessing my truck does not have any diff locks and if that's the case I would like to get them installed at least in the back. Any ideas or suggestions? 97' XLT 4x4

 

AXLE CODES
B6-3.73 limited slip
H9-3.55 limited slip
B5-4.10 limited slip
X27-3.31 open
X19-3.55 open
X26-3.73 open
X27-4.10 open

Sticker on your door jamb.

 

Ok there is a 19 under axle so i'm guessing its X19-3.55 open. Any suggestion as to what type or brand of locker I should go with?

 

what's your budget

 

under 500$ i guess

 

Look for a used detroit locker.

 

Aussie or spartan

 

Lincoln Locker. It's free hahah. Some people advise against it but a few of my buddies have them on their DD's and have had no problems. But if you're not comfortable welding your diff then I'd say Aussie

 

Detroit true track

 

So I got 2 votes for Detroit and 2 votes for Aussie haha. I'll look into those. Thanks guys that gives me a starting point.
