I have a 2008 f150 Xl 4.2L I know that the acceleration and speed are supposed to go down, but mine is rediculously bad. It takes me forever to get up to speed. I was wondering if changing the gear ratio would work? If not what suggestions do you guys have. Thanks

 

it has a 6 inch procomp lift on it too sorry

 

A 4.2 with a lift? What size tires? Ouch!

And here I am thinking my 5.4 with the stock tires is a turd..lol.

 

yah dude its got 35's sooo yah any ideas?

 

besides power adders like a supercharger, gears will be the most effective way to get some of your acceleration back.

 

who woud i take it to to do the gears?

 

any drive train shop can do gears. also call around to local mechanics and ask if they do gear swaps.
