im tryin to find out if my rear end is 9.75 how do i do this? i kno its on the driver side door but im not home, so its my wife checkin for me wat exactly am i lookin for? and how do i search online to find out? thanks guys

 

normally if you have the 5.4 you have the 9.75 rear diff and 8.8 front. if you have the 4.6 or 4.2 you have the 8.8 front and back.

 

ok thank u, do u kno how to confirm that it is? im bout to buy gears and i just wanna make sure im not buyin for no reason.

 

should be a tag on the diff. that or search for that link where you put your vin at the end and it gives you your window sticker. if you have an 8 foot bed you have a 10.25 inch rear, if its not, and its a 5.4 its a 9.75
