4.56 gear

[Torque77]

I'm having 4.56 gearing installed tomorrow. I'm tuned with HP. I have long tubes and a 3K Circle D with stock 3.55's. I'm curious if the truck will drive ok till I tune it again for the new gear setup. Or do my concerns not matter in regards to this?

Thanks.

As long as your current tune was done properly then you won't have any issues after the gears are installed. Nothing in the VE table is going to change or with the timing as well.

You will enjoy the 4.56's. They make the truck so much more fun to drive versus a 3.55/3.92.
The 4.56's allow these heavy bricks to get moving with a lot less throttle input.
