Ive got a 318 with 6 inchs of lift all suspension and 35 inch tires.... I got 4.88s installed... Guys it runs like a champ... sooooo much power has been given back to me, on high way it does great. Its my DD, I take highway to school everyday too. So much stress off tranny and TQ converter.
Highly recommended.

 

whats your milage lol

 

Better in town actually, around same on highway maybe a lil less.. also its about 4-6 MPH off but just get a tom-tom or borrow one and figure out correct mileage.

 

OMG yes finally somebody with 4.88's I want to know everything lol. Rpm's at say 65-70, mpg, and exactly what kind of power are we talkin here? I'm working up for 4.88's in a couple weeks.

 

I just had them installed in my truck too. rpm's at 60 with 35's is 2000 in OD. dont know mpg yet, but get up an go around town is awesome! trans no longer hunts on the freeway. highly recommended!

 

you have sct ? highly reccomend a tuner ! possbly superchips for tire reset .

 

Just what I wanted to hear. I can't wait to get mine in.

 

YES!!! 4.88s man, I own the hills haha, my tranny and TC love me again lol, you definatly get your giitty up back, its pretty awesome man....shift points are much stronger and your RPMs dont sky rocket goin up hills they gradually climb as your truck does... HIGHLY RECOMENDED! and yes im soon getting the SCT tune from hemifever.
