4.56 will put your engine RPM back to where they were with the stock tires/ratios. 4.88 will bump it up about 200 RPM at 60mph.... if 99% of your driving is 55 or less, I would go with the 4.88's, and enjoy the additional torque you would get.

How many miles on your trans? That might be another area to look at.

 

Now no laughing but it's the factory tranny with 96,3xx miles on her . I don't go far for work .. I added a shift kit and extra tranny cooler will 4.88 fit in my stock 9.25/Dana 44 axles?

 

He is already running 35's....and 5" lift.

Tranny (Mega Viper) and Gears would be best bet, but the money you mentioned will do one or the other. Gears will help save tranny and improve efficiency. And you can get 4.88 for that 9.25 diff. There are several threads here on gearing. I have not done this so I don't know what all is needed for this.

 

Are 4:88 to much ? As in is my very little highway drivibg going to put my engine at risk if I hit 70?

 

Also from rockauto I can get front back gears and both install kit with carrier for $600 how's that sound

 

No risk...just turning about 2400 rpm instead of 2100-2200 at 70 mph.

 

You have $$$$?

Hell, son -- HOOKERS AND BLOW!!!

 

Damn buddy I still think gears are cheaper haha

 

The 4.88's would fit the bill just right, I love mine. You don't need a carrier for the front, just get a thick cut gear. They're the same price and saves you some coin for the hookers and blow lol.

 

Now we're talkin thanks guys
