Question & Answers
Q: What would be the correct install kit to order to install the G2 4.56 gears on my 1989 K5 Blazer with the GM 8.5 axles Answer this question
A: Use the G2 GM 8.5 Inch Master Ring and Pinion Installation Kit - PN: G/235-2021

Q: 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? Answer this question
A: 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.

Q: 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 Answer this question
A: 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.

Q: 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 Answer this question
A: 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
