F350 spring codes?

[Feed Bunk]

Well my dana 60 project got put on hold for a while, but scince it wont stop raining Ive got time to work on it. I have all the parts I need except for front springs. When I called the spring shop today the first question they asked was for the spring code thats on the inside of the door. Scince my truck is an F250 I have no idea what code I need. Any help on what number I need would be great. Thanks

I think they're looking for the GVW info to see what axle you currently have under the truck.

Here's a vin decoder that will break down the info for ya.

Mine are T4F. The sticker doesn't specify front or rear springs. I think the front is T4 and the rears are F but dont quote me. And this is a 460 truck but from what i am told there were =only 2 springs made...small block and big block/diesel springs
