where to start!?!?!

Yukon gears are an upgraded ring and pinion set for your stock axle. Because you're improving the performance and gain some extra torque, it's needed to help bring down the RPMs and to keep your transmission from dropping down gears on steep hills.

You can find them on Summit Racing, 4WheelParts, JEGs, etc. Just make sure it is for your axle model (GM 10 bolt) and the proper gear ratio.

The limited slip aids with getting the power to the ground. It's basically an "in axle" traction control.

B&M
Powerglide

those are just a few torque converter companies that come to mind. Make sure you order (and research) the correct stall value. 3400-3800 seem to be the best number for our pigs.

Good looking out for them. Although. I am running a 2800-3200Stall converter,
But that's in a 4L80 fully built.

For the others.
G2 is a brand that I perfer.

Also let me say this changing the gears in your Rigs IS NOT going to give it more POWER what is doing is changing where that POWER comes in to play. Before you change gears you need to know what gears you have I.E. 3.42's or say 4.10's possible in say a 2500 Yukon or Sububran stock. I like the low end to mid range that my 4.10's give me. I'm about to install a set in the wife's because it is getting lifted slightly.

When going bigger I have always lived by the theory of

Tire size 31"-33" = gears 3.73 - 4.10's.

Tire size 34"-36" = gears 4.56 - 4.88's

Tire size 37" -38" = gears 4.88 - 5.13's

Am I reading this right? Actually gains from a $16 "Corvette" servo? Does it work in a 4wd also?

The Corvette servo is usually done in conjunction with a shift kit. Helps the truck shift better and provides more holding pressure. Helps the trans last longer as well since it doesn't slip as much.

Very worthwhile upgrade. Works all the time.

Looks like I have found Upgrade #1

You will also need to do a shift kit to truly benefit from this mod.

Can anyone recommend a shift kit and where to get one?

Lots of good info in this thread.

Transgo HD1 or HD2 (I forget which, but pretty much the standard to go to for shift kits)
