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.
