Alright guys and gals... I see a need for a glossary for abbreviations here. Now, this ... hopefully .. should apply to the whole site and not just to our section. Since no one has done it (that I know of) help me out.
Edit: MGDfan came up with a partial list to which we have added

Besides the obvious of LMAO, ROFL, WTF, , let's get a list going to have it posted somewhere for all to see.And all of 97-03 can share credit

Edit: and now with HHHoagie, who posted a pretty good list in 2004.

We have included terms maybe only used on this site... IDK... such as NBS, OBS, IMHO. IIRC.... ect., ect.

Edit #2: MGDfan found yet another list of abbreviations and definitions, posted by Steve83 on 4-25-09 at another site. It is quite long and detailed so here is the link : http://www.fourdoorbronco.com/board/...-Abbreviations

Dtf???? Haha jk

 

I can't even say what I would translate that to. I'd be banned

 

SFA- Solid front axle
SAS-Solid axle swap

 

^^^

Screw and scab and rcab rc/sb(rcsb)

 

??

See what I mean?? Nevermind... just HIT me!!

 

mpg

miles per gallon

In all seriousness though...HFCs= High flow cats

 

Good Start so far. Thanks All .. I will keep this updated as long as it continues... then alphabetize and hopefully the Admins. will transfer it

 

CAI- Cold air intake

rear wheel horsepower should be RWHP, not RWH

 

Some may not know that one so it's in there

 

Hmm, just a few of the more common ones I can think of right now.....

AAL = Add A Leaf
WOT = Wide Open Throttle.

Good idea btw (which equals "by the way")

 

Thanks. For all of it

 

So the list grows Keep'em coming. I'll check back later

 

TT= trailer tow
TTT = telescoping trailer tow
ttt = to the top

 

exhaust....
LT - long tube (headers)
SI - single in
DO - dual out
SO - single out
DI - dual in

DIY !!!!
