I know this topic has come up more then anyone wants but I'm new to this and didn't find much on the newer model silverado's. So I currently have a 2015 5.3l 4x4 Silverado and ordered (but not installed yet) the mcgaughy 7-9" SS lift kit with plans on setting it to 9" .. Fuel maverick rims and 37" tires. I also order a complete master ring and pinion 4.88 kit with a Yukon duragrip clutch type posi. Is this gear ratio a good setup for what I have and plan to do? Has anyone done a similar setup or know of anyone who has? I don't want my rpm's to be at 3000 at 65mph. A few say it won't be that high and others say it will. Does the tires make the only difference or does the lift also factor in when doing a regear? The shop I'm talking to said the lift doesn't make much of a difference (saying it does but not enough to notice) and tires is where the main factor comes in. I don't want to end up putting something in that's overkill ? I have a few other questions but I'll start with this and see if I can get any help or info. Thanks
