Re: towing
The axel ratio is number of revolutions to one turn of the axel or 342 to 1, in other words, the higher the number the more you can tow. Granted you are towing a large boat,but I have never run ito a suburban that could not tow a house let alone a boat. Contact the GM web page, go to ?? and ask, they will respond in one to two days with the answer.
