    Question Gears!?

    I have no clue on what gears to get for my truck. I have an 02 Silverado 4.8L 6in lift 35x12.50 tires. Stock it has 373's in it and I've heard people say 456's are good. I want my power back and I still want top end speed. Any suggestions???

    I would go with the 4.56. Here's a gear ratio calculator. Click Here

    I'd go with 4.56s as well...maybe even 4.88s since you have a 4.8L engine. I went with Yukon gears from Randy's ring and pinion.

    X2 on Randy's Ring and Pinion. They have good prices and there's plenty of tech help if needed.
