Default 4.88 Gear Manufacturers?

I recently performed the following mods:

K&N cold air intake
Gibson shorty headers
Flowmaster exhaust
Cognito upper control arm leveling kit
Cognito HD OEM-style tie rods
Cognito pitman/idler kit/support
Bilstein front shocks
37x12.50x17 BFG Mud Terrains

With the 37s the truck feels like it can't get out of it's own way. I've read through some posts regarding changing the gear ratio. I'm leaning toward 4.88s...most of my on-road driving is below 70 MPH and I rarely ever tow, so 4.88s seemed like a good choice. (feel free to chime in on this...as I do a fair amount of off-roading too)

My main question is; what is a solid brand to look for when shopping for gears?

Hi these are some of the best companys out there: RICHMOND, STRANGE, PRECISION GEAR i have used gears from all these companys and never had a problem. Their are some other good companys out their to. Just make sure the guy who installs them knows what he is doing and has all the correct tools to do the job correct. I would put new bearings and seals in at the same time. Hope this helps

Go with precision. The other gear companies are good but for the price and quality, you can't beat precision.

The one company I wouldn't go with are ZOOM. I've used them in the past and went through several sets do to flaws in the castings.

Good choice on the 488's. My last H2 I installed 456's and wish I had gone up.

You'll see a post in a few minutes where I'm getting ready to discuss me installing a set of 488's next week. (and I've got a supercharger)

I found precision's site but can't buy from them. I did a search and found a set of motive gears but only for the front.

I'm still looking, if I come up with a good price, I'll post it here.

Don't forget, you'll need an installation kit.

I forgot about these....

Probably one of the best prices and you know they'll be the right parts.
