I don't think that TR is your axle code since here is a list of AXLE CODES
But, on a SRW PSD the only option would be 3.73 gears. The code would help you to know if you had a limited slip or not.
Or look at the tag on the rear diff cover....the second line should start either 3 73 or 3 L 73 if you have the limited slip. Just FYI, sometimes the first number is covered by one of the diff cover bolts.
Hope this helps.

Double check that, Jim. All axle codes are either a two digit number, like 45, or they're alphanumeric, like C5. You might be picking up the trim color code, for example. At least, that was the case pre-'99. If someone else has more accurate information, step up.

On the certification sticker on the lower doorpost behind the driver's door, under "SPR". There will be a two-letter code. The first letter is the front springs, and the second letter is the rear springs. On a 4x4, the front spring codes are:
S = 4,000 pounds @ground
T = 4,400 pounds @ground
U = 4,800 pounds @ground
V = 5,200 pounds @ground
W = 5,600 pounds @ground
X = 6,000 pounds @ground
Code W front springs are rare on a pickup - usually on gasser F-450s.
Code X front springs are reserved for F-450 PSDs, as well as for PSD pickups with the snowplow pkg.
Rear spring codes are A, B, or C.
A = F-250, '99 thru about midyear 2001.
B = F-350 SRW, plus F-250 since mid-year 2001.
C = F-350 DRW
On the pickups, code B rear springs are rated at 6,830 pounds combined rating @ground. Code A = 6,084. Code C = 8,250.
S = 4,000 pounds @ground
T = 4,400 pounds @ground

I have a Fisher 8 foot snow plow mounted on my truck. With the T springs, is this appropriate for my truck or should I invest in a heavier duty leaf springs for the front end? The Ford dealership I bought the truck from said it could handle an 8 foot plow with no difficulty. The front end of the truck goes down an inch or so when I raise the blade off the ground. Thank you.
