Review from Yukon Gear 8.5 in. & 8.6 in. Rear Ring Gear and Pinion Kit - 4.88 Gears (07-18 Sierra 1500)
Excellent set of gears. Provided you have all the necessary tools, you can change your gears in your driveway easy. Local shop wanted $1600 for just the rear gears (double that if you have a 4x4). $300 and a solid Youtube video later, I have all the power that I lost when I upgraded to 35 inch tires, and then some. The Yukons make a little more noise than the manufacturer gears, but they're like half the price, so I thought that was a fair trade, plus when I upgrade my exhaust, it'll cover it.
