I don't have anything good to say about these gears. I don't know if there was a bad batch of gears made or not. I know we bought these gears and had them put in and the next day the truck had to go back to the shop. That was the first set, then the second set was put in and the same thing. They were heating up, so the third set was put in and of course the same thing. So now I'm hoping we can get our money back and buy another brand of gears. All this in a months time. The gears were heating up and causing the grease to come out and making a terrible noise and the truck had a vibration while driving. We have only drove the truck from and to the shop where the gears were put in.

Question & Answers

5 Answered questions

will this work in my 2007 Silverado 4.8 new body style and do I have to buy the master install kit for it to work?

Asked by Silverado07 from on

Hello Silverado The G/22-2021-456 Ring and pinion will fit your 2007 Silverado 1500 4.8L with a 10 bolt rear end. You will need the master install kit part number G/235-2022 to correctly do the installation. The 4.56 gears will work best withy a 35 inch tall tire. Thank You for your question.

I have 1999 Chevy Silverado 5.3 with 3.73 gears. The truck is lifted 6inches with a Superlift (suspension lift) with 35"x10" Nitto Terra Grapplers. What gears would be best to compensate for the loss in torque from the lift and tires

Asked by Hayden from on

Thanks for the inquiry Hayden, the G2 Axle and Gear GM 8.5in. 10 Bolt 4.56 Ratio part # G/22-2021-456 we would recommend this ratio for that tire size.

Since I have a 4 wheel drive, I would also have to swap out the front gears as well correct? What would I want for that

Asked by kyle from creston on

Hello Kyle You would need the same ratio for the front end also. You didn't say what year the truck is so I couldn't give you any part numbers. Thanks
