As Mentioned, 4.56 is what you will want and if you do plan on 37's, 4.88. Not sure if I missed it but depending on your current gear ratio in the sport, you may also need a new front carrier due to the case brake going to a thick gear, just keep that in mind. A new open case will run you around $130.
Thank you everyone for all of the kind words and referrals! You all are awesome!
For clarification on our pricing, we charge $1,820.00 in labor for front and rear with master install kits. This also includes a 500 mile break in inspection and oil change. A full gear package in parts will run $1,095.99 +tax. So roughly $2,915.99 out the door.
