ok so i got some t-bars out of a sport trac at the junkyard today. i thought that all sport trac's came standard with #1 bars. i noticed under the spring rate on the door tag it said "B1". i figured that since it was a sport trac it was supposed to have #1's, and i didnt think they made #1 rear leafs. so i figured they just put the order backwards on it and it had B leafs. well i got them all out and looked at the sticker on them. one says RUB and one LUB. those are the exact same letters as the ones on my truck and i have B's. so then i looked at the p/n on it and they are PN: F57A. i read that the #1's are F67Z. and that the F57A is the B bars. so any ideas why this ST came with B bars? also my stock B bars i had cranked about 1/2 way up from stock for about a year and they stayed fine. then when i SL'd i maxed them. after putting the winch on and such they have sagged all the way down to about stock or even a little lower height in less then a year. also my truck has 185,000 miles or so and this sport trac had about 100,000. also both adjuster bolts were even so its like they didnt even have to compensate for the gas tank yet, so do u think they would still stay about maxed for about a year or so at least? cause in a year i will probably either have C/O's or SFA. im pretty good friends with the guy at the junk yard so i told him that these might not be the ones im looking for so he said just take em and see if they are...if they are come pay me and if they arent i can just go switch them out for some #1's. but there is only one other set in there that i know are #1's. they are on a v8 mountaineer. but the pass one is maxed for some reason so i didnt want to get those if one side is already really sagged...not sure why it is the pass side tho. thanks for any help

 

Bump...tryin to see if I should put these in or not

 

well i put them in and it is still too low....maybe a little higher than before. time to take them back and find some #1's....i guess the winch and stuff is just too much for B bars.

 

Definitely. It's almost too much for the #1 bars...
