Ok guys help me with my spring codes. I have read the faq's section and I cant seem to match that with what is on my placard. It reads SPR and under it has the code TTPP what is this exactly? My truck is a 2004 Crew Cab V-10 4x4.

Thanks Corey

 

Front leaves (T) are 4400 lbs, rear leaves (P) are 6830 lbs.

 

n578md, mine has TTFF as springs. I was told the TT front springs were 5200# and nobody has told me what the FF rear springs are. Any ideas? Thanks

 

Sorry Stew, I don't have anything on the 2005's coils yet. So T could be a 5200 lbs coil on a 4x4 truck. As far as the rear springs are concerned, there are 7 different leaf springs available in the 2005 BBA books:

F250 Main spring only: 6100 lbs
F250/F350SRW w/ aux spring: 7000 lbs
F350 DRW: 9000 lbs
F350 SRW Chassis Cab : 7280 lbs
F350 DRW Chassis Cab : 9750 lbs
F450: 12,000 lbs
F550: 13,660 lbs

So most likely you have a 6100 lbs rated spring pack if you only have 5 leaves or a 7000 lbs rated spring pack that has 6 leaves including the auxillary spring. The auxillary spring is easy to spot, you'll know if you have it. Here's what it looks like on my 2003, the top leaf with the yellow sticker is the aux spring:

I got this from a ford spec book, this is all they have... (i.e., nothing for the rear)
