Im gonna be running 35’s with a 6 inch lift on my 2010 DC 5.7 and I have a few concerns before I get going on..
1.[FONT="] [/FONT]I know with bigger tire size comes certain changes. Ive been told that im going to be wasting more gas and due to higher rpms im also gonna put more wear on my engine. I was recommended by a friend to change my rear gear to a 4.88. Can someone recommend me a place online or a local shop in so cal that would have what im looking for? im assuming from some of my research that im gonna need a 10.5 rear with a 4.88 ratio.. please correct me if im wrong.
2.[FONT="] [/FONT]What are the affects of this ratio change? Will it improve my mpg and my acceleration?
3.[FONT="] [/FONT]Also with tire change I understand that my speedometer is gonna need to be recalibrated. Is there a handheld I need to buy or would a professional tire shop be able to take care of this for me? Also is there anything else that im going to need reconfigured or recalibrated?
These are my main concerns as of now. As I go along I might have more questions. I searched and searched online and found very little information on rear gear changes for 5.7 tundras so im hoping you guys can help me out. Any information I get is greatly appreciated!
