Gears?
I recently added a 2" leveling kit and upgraded to tires size 285/70R17. I have the 3.55 gears with Limited Slip Axle. Do I need to regear for this tire configuration?
Even if I don't need to, will upgrading my gears to, say, 3.73 give me better truck performance and more power? I also plan on getting an Edge programmer....
How much do gears cost?
Thanks for all advice.

But shorter gears will help in the performance department.
Skip the 3.73s, they are too close to what you have and the cost won't be worth it.

You're looking at around $300 for the gears and install kit and anywhere from $250-$450 labor to have them installed. Shop around, as labor rates for rearends vary greatly. Double the cost if it's 4wd.

Thanks.

Slightly higher RPM at all speeds, so your MPG may decline. But in all honesty, I went from 3.31 to 4.10 and my mpg wasn't noticeably different, and after reading a lot of posts on this forum, others say the same.
IMHO, a programmer won't give the same result as the to-the-wheels torque multiplication of gears.
My bro-in-law's truck is a dog compared to his friend's truck. Identical trucks on 35, only my bro-in-law has a programmer on 3.73 gears, while his friend has 4.56 gears and no programmer.

Thank you for all the info. I just need to know a few more things...
Where can I get the gears (and installation)? Are they actually in the transmission? Sorry I don't know much about them...
What about 4.56 gears? My truck is really sluggish lately and I want to improve it A LOT. Would that be too extreme for my truck?
Most importantly, are there any downsides? Will this damage my engine or shorten its life in any way? I have 115,000 miles and I need it to last....

question, you see my truck? do you see, ok i want to put a 3 in. body lift on it (my friend said it makes the truck weaker, but i don't know about that) and i want to put 35's on aftermarket wheels, i have 3.73 gears, should i go to anything higher, and what if i changed gears with out doing the lift and tires, is it a big difference from 3.73

And I have never heard of a body lift making the truck weaker.......Maybe if you don't put all the bolt's back in?

Don't do a body lift, dude. I have a friend at school who drives the EXACT same truck as you (same color and everything), and he put a body lift on it and it looks HORRIBLE. I have driven it before and after and after the body lift it feels like the truck is gonna roll over all the time. It makes it feel really wobbly.
When I was looking around for a lift for my truck, I was told by several people that body lifts do cause a serious reduction in power. Not to mention the smooth ride of your Ford is completely gone.
Your choice, though. If I were you, I'd save up for a 3"-4" suspension lift and put aftermarket wheels on with some 35s. If you can't do that, put a leveling kit on the front (because your truck is 4WD, I'd go with the 2.5"), and throw some 33s or 35s (35s will fit because your truck is 4WD) on your stock wheels. Trust me, it will look really nice.
I'm sure Wandell can chime in with some useful info.
Good luck.
