gears......whats that?

i recently got some 33s for my 2wd edge and i lost a lot of power, especially going up hills on the interstate i have been thinking about getting different gears but will they actually help the problem im having?

what do the gears actually do for the truck?

thanks.

I like this one a bit better then the wiki one. Without really explaining, yes re-gearing will help you. If I get some time today I might try to explain it, but I think it's been covered before. Might try searching.

Changing the gears inside the differential to a ratio with a higher number (like from 3.73 to 4.56) means that the pinion gear will rotate more times in relation to the ring gear, which gives you more mechanical advantage. It's like the difference between gears on a bike: If you use the biggest front with the smallest rear, it's hard to start out. If you use a smaller front with a larger rear, it's much easier to start pedalling.

Yup, the gears for 33's that most people will suggest is either 4.56's or 4.30's (only 2wd trucks can get 4.30's as they don't make them for 4x4 trucks)

Hell I'd say he'd be fine with 3.73's or above. I've been running those in my truck with the 33's over 2 years now at it works good for me. But 4.56s would be fun. Haha....

Now granted I've got a 4.0. So the engine makes a big difference as well. If you've got a 3.0 or lower you'll probably want the big gears. Not sure what 2WD Edge's come with.

Re-Gearing after a substantial tire change is one of the best investments you can make. BUT, make it worth it because re-gearing and axle work in general isn't very cheap. It's labor intensive, and if you're asking this question it's probably best to have a shop do the work for you. Expect to pay at least $150 to have a rear ring and pinion set up by a shop.

The best bet is to find out what ratio you currently have in your truck.
Post that here.

Then tell us if your Edge has a 3L or 4L engine.

I'll argue that a jump from 3.73 to 4.10 is not worth it, financially. A jump from 3.73 to 4.30 or 4.56 would justify the cost to me.

And while you're in there, ask yourself if you want to much wheelin' with this truck. Re-Gearing offers the perfect opportunity to add a locker or a limited slip. You won't have to pay the shop much (if any) extra labor charges to swap an open carrier to something more off road friendly (like a locker).
