ring and pinion gears - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am wanting to know if GM made a rear gear set ( ring and pinion) for our trucks with a gear ratio that is in between a 4.11 and 4.56. I would like a 4.30 or 4.33. I know they offer one for ford 9 inch, just wondering if GM made that ratio for 12 bolt that are in our trucks.

Not to my knowledge ---just the jump from 4.10 to 4.56

Do a search on the internet. I remember seeing one of the major gear companies that made one for a 12 bolt. Sorry I don't remember which company it was.

I did a little searching and I didn't find any 4.30 for trucks. I only found 4.30 for 12 bolt cars. I'm sure I didn't find all options. Hope you find one.
