Ford F150 - VIN Letter Question

I was looking at the VIN last night on my truck and the 4th letter in the VIN is a "Z" I know it is referring to the brake type but I have been looking at the VIN decoder sheet and I do not see the letter "Z" in the list. Not that I am worried, just curious as to what it means.

The fourth letter refers to the engine, it is located in the middle of the list.

4. Engine Type

Z — 5.4L SOHC, gaseous fuel prep, eight cylinder (Econoline, F-150, F-250)

I guess I should have said it is the 2nd letter is a "Z", sorry for the mix up.

2.Brake Type

"Z"

Maybe the vin has been altered?

The 1st digit is the nation of origin.
The 2nd digit is the manufacturer, which should be an "F"
The third digit is body type.

He's talking about the fourth digit in the vin.

Perhaps they are drum brakes?

The truck has disc on front drum on rear. Here is the fist part of my VIN - 2FT Z F08. The "Z" is what I am trying to figure out.

wow ive been looking and i did find a Z.... under a 2002 F-750 workshop manual!.... here it is...

this... does not sound correct lol.... message me your whole VIN and i will try to run it.. see if it works. double check the original vin... the one on the door and on the windsheild, just to make sure.

The VIN 4th digit is brakes/restraints/GVWR. The engine is the 8th digit.



The fourth VIN position is for the brake system and the gross vehicle weight rating (GVWR) class. All brake systems are hydraulic. The codes are:
> A — Less than 3,000 pounds.
> B — 3,001 to 4,000 pounds.
> C — 4,001 to 5,000 pounds.
> D — 5,001 to 6,000 pounds.
> E — 6,001 to 7,000 pounds.
> F — 7,001 to 8,000 pounds.

According to the '97 CD, "Z" is not a valid value for the 4th digit on your VIN.

Well the truck is a 1998 model, but anyway. Seems like I always own something has something weird to it that can't be explained. Once again it doesn't really matter, was just curious what the "Z" was for. I know that I have brakes and they stop me, so that is what counts. Thanks again for everyone’s effort, I greatly appreciate it.

I dunno why I thought it was a '97 - here's the list from the '98 CD.

The fourth VIN position is the vehicle brake type and GVW code (all vehicles use hydraulic brakes).
> A — 0-3000 Pounds
> B — 3,001-4,000 Pounds
> C — 4,001-5,000 Pounds
> D — 5,001-6,000 Pounds
> E — 6,001-7,000 Pounds
> F — 7,001-8,000 Pounds
> G — 8,001-8,500 Pounds
> H — 8,501-9,000 Pounds
> J — 9,001-10,000 Pounds
> K — 10,001-14,000 Pounds
> L — 14,001-16,000 Pounds
> M — 16,001-19,500 Pounds

> F08 — F-150 Flareside, 4x4
