Howdy. The manual for my 2013 Silverado crew cab short bed says: 5.3L..V8..K5L HD Colling package.. 3.08 axle ratio..maximum trailer weight 6700 lbs..GCWR 12,200 lbs.. great..so I think I am looking at a max trailer dry weight of 5700 lbs or so given that 1000 lbs has to be set aside for hitch weight and such..so my question is: the Silverado one step up has a gear ratio of 3.42 and max trailer weight of 9500 lbs..How can I get my trucks gear ratio higher without voiding warranty. If i cant I guess I will look for the trailer that will work within my specs since I am keepig this truck. Advise please. Thanks! Passengers are me wife a 10 and 14 year old girls

put a 3.42 axle in it. Would be expensive.Unsure why you think it would void your warranty????What does changing your ratio have to do with warranty?

I know it would be expensive, but could you discuss changing the differential with the dealer?

Passengers are me wife a 10 and 14 year old girlsTo make a good decision about staying within limits we really need to discuss:GVWRGAWR rearGAWR front....these numbers will be on the door sticker.Forget trailer "dry weight". Best to think in terms of what the trailer "really weighs". A pretty good starting point of discussion on that is 1000 pounds over the dry weight.If this is a 4WD truck, then changing gears is going to be fairly costly.

You could have it changed at a shop and the dealer would never know. But if you do,put 3.73 in.

You are looking at the most optimist set of numbers that apply to your vehicle. Payload is where you will most likely hit your limit, regardless of the rear axle ratio. Best thing to do is get an actual loaded weight and subtract that from your GVWR to get some idea how much tongue weight you can handle. I traded a 2012 Silverado like yours to get the capacity to tow a 7,000+ pound travel trailer.

To make a good decision about staying within limits we really need to discuss:
GVWR
GAWR rear
GAWR front

....these numbers will be on the door sticker.
