B-Pillar codes....

Hey ya'll,It's been mentioned before that a Few members on here can decode the stickers on the B-Pillar.I have a few codes that I would like to check up on.The truck in question is a 1980 Ford F100.

I pretty much already know the truck from top to bottom,but it doesn't hurt to be sure.

Judging by the shape of the trans pan,I believe I have a C6.The trans code is K.I was wondering if that offers any more info on the tranny,or just what it is?

The other code I need is the Axle code,which is 13.I already know it's a 9 inch,and I believe I have a 2.75 gear ratio,but like before,I just want to be sure.

Thanks for all the help!

trans code K= C6 automatic

Axle code 13 = Ford 9" / capacity 3750 / 2.75 ratio.

Axle code 13 = No Limited Slip.

If the axle code begins with a letter: Limited Slip.

If with a number = No Limited Slip

Thanks ya'll.I just wanted to be sure.

So,since my truck doesn't have limited slip,what does it have?I'm only used to limited slip and posi differentials.

And also,will not having limited slip affect the way the truck pulls a trailer?

And one last one,I'm planning on swapping to a lower gear ratio.I'm gonna be pulling trailers every once in a while,and the trailer will most likely be hauling other friends trucks or racecars.What would be the best ratio to go with that will pull these loads with ease,but still get decent gas mileage?I know that when you haul loads you can forget about gas mileage,but I don't want to put more gear in the truck than I need.This truck still has to be my daily driver.Thanks for all the help!

BTW,truck's a 1980 Ford F100,and the rear axle is a 9",if it helps.

Just a regular axle with non limited slip.

Not really. Limited slip is used only if one tire doesn't get traction. some of the power is transfered from the slipping wheel to the stationary wheel so you don't get stuck as easily.

You don't have the truck for that kind of towing weight. You would need at least a F-150, preferably a F-250.

As I said before, you don't have the truck to tow that kind of weight. this is coming straight from the Ford books I have.

The maximum allowed towing weight of the F-100 is 3500 lbs. A truck or racecar can run in the weight range of 2 tons easy 4000 lbs+.

The minimum axle ratio for towing with the F-100 and 300-I6 is 3.00, and you are limited to 3500 lbs or less with a class II hitch.

Remember it's not just the pulling, it's the stopping as well.

Well that sucks.I was afraid of that.

But I was planning on getting an F150 as my second truck,so I guess I'll use the 80 for a highway driver and the F150 for towing.

But thanks for all the help.

Or you could get a F-250 with a 460 for pulling.
