What add does the FX4 package include.

What gears?

Does it have a limited slip or locking rear dif?


Thanks Guys


Still new here and trying to learn.

 

LSD ... Skid plates ... Rancho Shocks.

FX4+ has the fancy Lariat trim etc etc

Sorry cannot remember the Diff ratio.

 

it cool i guess someone else will chime in thanks alot

 

you could get 3.55 or 3.73's depending on the year. i don't think any of the shocks were rancho, they just had different valving. the limited slips are junk IMO. do a search, this topic has came up before.

 

2004

 

FX4's can be had with either 3.55's or 3.73's, or atleast they were in 04 and 05. 06-08 I am guessing are the same way, but I don't know for sure. The shocks are not Ranchos they are just valved different than the ones on other models of trucks. Skid plates, LS diff and different gauge cluster on FX4 models

 

how are they valved different

 

Ours came with 4.10 gears, 06 model

 

17"/18" rims gets 3.73 gears
20" rims gets 3.55 gears

all get a Limited Slip 9.75 axle



5.4 3v motor is standard

textured black wheel flares

skid plates

different interior
4.10 are not OEM gears on a FX4...or any other normal F-150. You can only get 4.10 on a Heavy Duty F-150 (7 lug 10.25 axle)

 

so if it says fx4 it is for sure a 5.4 3v the 300 hp motor?

 

Actually you could get 3.55's with 18's. One of my former neighbors has a truck that is a twin to mine, but completely bone stock. His has the stock 18's and also a different axle code and when I looked it up, the code was for 3.55's. His dads truck, a 05 FX4, had the same code. Maybe they switched something with the gear ratios when 20's became a factory option?

As long as it is a true FX4, and doesn't just have FX4 stickers, then yes it will have the 5.4L

 

Sometime in the 08 model year 4.10's became optional with the 18" and 20" wheels.

Should have been that way all along.

When I got my current truck, 3.55's were the only available ratio with 20's on an FX4. Later in the 07 MY 3.73's became optional.

 

here

is that a true fx4

 

Yes that is a FX4.

 

so it does have the 5.4 3v
