4.56 installed


Recommended Posts

Posted

Got my truck back from 4 wheel parts in Sacramento last night. They installed a set of G2 4.56 gears front and rear along with master rebuild kits. I didn't realize how much power I was missing after driving for so long with the 3.73 and 295 70 17 until now. It is like a whole new truck!

 

Now on to the questions and answers.

1- the tech said G2 recommended 85 140 during break in when I questioned the weight of oil they installed (Lucas). Is this right or should I switch back to gm recommendations.

 

2- yes it threw the abs light out of whack but selecting 4.56 gears with my superchips cortex programmer fixed the issue.

 

Over all I am extremely happy with the shop and gear choice. Hopefully this fixes the gear hunting during towing.

Congrats man, what rpm's are running cruising at say 70 mph? Can we get a vid?

Congrats man. I would leave what you have in there. The way I understand this, is that the new gear sets will generate a lot of heat while breaking in. Also, your heavy wheels/tires, as well as your lift, put you "under load."

I'm not too sure to be honest about switching back, but the break in is 500 miles. There's a lot of conflicting opinions about the weight issue. I can't recall what was put in mine when my gears were done, but I didn't go back for a 500 mile oil change. I had my gears done by a very reputable differential shop and he said I didn't need to. He gave me some restrictions but essentially told me to treat it like a new vehicle otherwise. Maybe contact g2?
