Im running 285/75, with the 5.4 on my 02, and it seems kinda sluggish, thinking I need to regear. From the sound of it 4.10 is the way to go. My question is what all do you need to purchase for a regear? I cruised ebay, and saw 4.10 gears selling for like $70. But then read how people are spending 1k + for new gears installed. So Im thinking Im leaving something out.

 

The labor on the install is whats expensive.

 

So its not one of those DIY things?

 

hell no.....and you need to buy installation kits which a run you a few hundred....im in the process of trying to regear too....goodluck man

 

Great, this is gonna cost me I see. Will running the 285/75 hurt my transmission while I wait to save up for new gears?

 

you should be okay. several members have run up to a 35'' tire on stock gears no problem, myself included. however, when you start trying to run 37's on stock gears, that's where you break transmissions.

 

JNC995 What gears are you running right now?
