Anyone know if the 2002 FX4 come standard with 3.73 limited slip gears even if door info says 3.55?

 

tjsfx4,
I don't think 3.73's were available until 03 (might be wrong here). If you don't trust the door tag, crawl under and look for a tag on the rear diff cover. If it reads 3L55..then you have a 3.55 as the door tag indicated.
Possible they got both wrong,...but unlikely.

For 02 the 3.73's only where available for Supercrew and 7700 group 4x4's, so if you don't have one of those trucks you have the 3.55's. A limited slip deferential was optional not standard on all trucks even the FX4, so you may not have one.

 

Limited Slip was not even "standard" on FX4 optioned trucks..... The "FX4" option is the same as the old "Off Road" option was earlier... Skid plates and different shocks, plus the stickers.... That's about it....

You still had to order LS as an option if that's what you wanted.... Not too bad of a deal at only around $150 or so. I think you could get 3.73 as a option from 2000 on up?? I had a friend with a 2000 F150 that had 3.73's and the LS.. Both were listed as opions even thou his had the "Off Road" stickers on the bed!

on my 03 FX4 the LS and 3.73 were both options

 

I have a copy of an 2002 F150 Brochure and it says "3.73 Limited Slip (Avail. w/7700-lb. Payload Package only)" so it was not available for a non 7700-lb. Payload Package Supercrew as I stated earlier.

 

My buddy over at the local ford dealership said "the FX4 is equiped with 3.55 gears and an available limited slip with the option of 3.73's" he also told me that it was a $600-$700 upgrade.

 

the only 150 that you could get a 3.73 gear in was with the 7700 package as stated before.Exept the new body style because they are figin heavy.

 

well it is posible because i got 3.73 in mine from the factory with an LS on my FX4 03

 

My bad you are right they did offer that in 03.

 

 

Its still an option on the 04/05's
Its not standard on the FX4, 3.73 ls is an option.
