I have an 88 F250 XLT Lariat with a 5.8L 351w. My question is what is the stock axles on there? Or how do I find this out? And what is the ratio? Turning her into a mud runner but I was wondering if I needed to upgrade the axles or not.

 

check the axle code on the door sticker

 

Alright. I'll have my truck back from my ex's on saturday. I'll look then. THANKS!

 

oh and here bud
