I know its a littel off topic but where on my truck does it say what rear end i have ...like hellbound sais he has the 3.75...where do i find that

 

Still got the window sticker? It tells gear ratio on there

 

Look on the driver side door pillar near the bottom. There’s a white sticker with information on it and your rear end code will be there. Here’s a list of the codes and what they translate to.

Axle Codes

non-limited slip

X27 – 3:31
X19 – 3:55
X26 – 3:73
X25 – 4:10

limited slip

H9 – 3:55
B6 – 3:73
B5 – 4:10

 

I saw a 19 under axle but not an x..so i guess i got the 3.55 that good or bad ?

 

19 is going to be a 3:55 non-limited slip
