Door tag question, code?

Two trucks both 2008 F350 super cab long box 4x4 one is a manual (XLT) one an automatic (XL).

My question is on the door tag the XLT has the code 3L under the word axle and the XL has 37 in the same spot. Anyone tell me what the difference is?

There is a difference in GVWR and tire size, the XL has 17 inch wheels and the XLT has 18.

Do all swr F350 have the same rear axle?

Yes, they have the same Visteon 10.5" axle. The difference is 3L is a 3.73 limited slip while the 37 is a 3.73 non-limited slip...
