I am considering changing to 3.73s. I have call Ford, SVT, the racing section of Ford, the dealership that I work for and searched F150ONLINE. I have been given at least four different part numbers for the same gears.

For those of you that have made the change, what the heck is the correct code????

Also about 3.73's

 

I bought my 00 lightning about a month ago and absolutely love it. I am looking to get a chip and filter soon and also change to 3.73 gears. I would like to know the going rate for the gears, installation and whether they were installed by the dealership or someone else. Thanks!

The 3.73 gears cost around $180-200.00

The installation cost depends on the Ford dealership you have the install with.

Estimates are $300-450.00

 

The part number I have ordered is M-4209-H373, from Ford Motorsport for $199. The Ford dealers around here want $700 to install...so I'm taking it to a differential shop, for $300. that will be $500, not including the speedometer fix. I'm having that done in my chip.
