If you have alfaobd make sure to update the BCM for the gear ratio change

Just the Config 4 Axle ration correct not the transfer case high ratio and or transfer case low range reduction ratio ?

By the way holy FAWK ! just got my truck back from the shop ... there is such a huge difference in how it drives and how it holds 7th and 8th gear going up hill ! FAWKEN LOVE IT ... it doesn't search for gears any more and my mpg went up from 14.3 - 14.7 to now 15.5 on the way home through in town streets when before it would go down below 13.5 when driving around town lol ... I have to do the break in drives which I will do today as per the shop ... SOB I LOVE IT ALREADY LOL !

Correct. Rwd doesn't have a transfer case but if I decide to do it in the future im confident I could.

I tried telling people how much I loved my 4.56 regear. I'm glad you're happy with it!

NO WAY ! Next time you have to PM me lol ....

Worth it ? yes Goose most definitely ... the truck just moves so effortlessly now ... it's not search for gears at all and up Van Buren if you are familiar with it going North back towards Moreno Valley, it stayed in 8th gear up the hill all the way up ...

The install was just $850 .... they were recommend to me by Wes who hangs out with DMAXRYNO on youtube ....

So I go back tomorrow so they can flush out the old gear oil and add the new one ... which gear oil should I go with you guys ?

The shop owner says to go with any 85-140 ...he recommends mobile, lucas or valvoline ...which one do you guys recommend ?

SOB ...these Revolution 4.88s are the business you guys ... I am now able to push down on that pedal and does this ***** move now ....

Before on the highway if there was any upward hills it would seriously bog down and just start searching for gears ... now it stays in 8th all the way through without feeling like a damn slug ....

The other day it was raining and I hit the gas like I always did before the regear and SOB if I didn't make that rear end slide lol ...

My MPGs are a little lower right now because I am having some fun with the truck finally lol ..but I have also now hit over 16 MPGs in the city before I decided to go Ricky Bobby ...

So anyone with 37s on a 1500 with 3.21s or 3.92s, regear ! you wont regret it one bit !
