hey I have a 99 F150 4.6L XLT 4X4 with 33 inch tires and 3.55 gears. I want to put some FOX off-road shocks on the front instead of the Torsion bars. also what kind of power should I have with 3.55 hears and 33" because I cant even get the back tires to slip a little.

U need 4.10 or a bigger motor

Alright I found gears for my truck cheap would it be ok to go with 6.10 and will that kill my gas mileage?

Use im if you want to drive around all day at 40 mph. The tac will redline and you won't be at the top of the hill yet for another 1/3 hour.

Really hope that was a typo lol 6.10s wouldn't be put in anything expect a designated trail rig. Even then would need like 52 inch tires

Really? I found them online on Jegs.com for cheap. And what would be the best ones to use and still get good power and gas mileage with?

You need 4.10 gears if you want it to be driveable on the highway. 6.10s would be ridiculous.

As for your question on the shocks, changing them isn't going to let you remove your torsion bars. You need them both.

It sounds like you need to do a bit more research before you start modding your truck....

If you want to get rid of your torsions you'll need coil overs not just shocks

Yeah I know but where can I get that kind of setup for cheap?

A set up like that won't be cheap a you'll have to have all kinda measurements suspension travel you'll need spring rates as far as I've seen there isn't a compony I mean you'd probably need custom mounts and all kinda stuff more work then it's worth
