Ok this is going to get long and I'm truly sorry, but need some help. I'm pretty new to the whole Differential part of turning wrenches. I know just enough to get myself in trouble. So when because its only a matter of time before I ask something stupid because i'm ignorant.
So.... With that said. Tuesday I'm going to my differential/axle guy. My old roommate who I trust as gone to him for years and years. I'm sure I'll find out a bunch more about what my needs/wants are, but I can't freaking stand it just thinking about it and not knowing. Plus want to make sure I'm on the same page if I can be.
Few things needing answered:
1. Gears what ratio?
2. Differential covers?
3. Lockers?
Back ground of the truck:
Right now I'm running 35s but 37's are coming. There is glass for the front fenders showing up as well. So other that TRR to run out my old 35s it will be 37s... maybe bigger down the road... from here on out.
1:Gears
I'm thinking that 4.88s would be great but have thought about 5.13s.
Questions about the gears
1. Will 5.13s fit both front and rear?
2. Any downside to 5.13s because it does something that isn't as good as 4.88s?
3. Any company of gears you recommend and why?
4. Would like quite gears but my tires are so loud not that big of an issues. My main thing is the really good/tough gears. Which company?
2: Differential covers
I'm wanting to do a Mag Hytec cover for the rear because it will be easier to mess with changing/checking fluids and how they look.
Questions about diff covers
1. Can I get a Mag Hytec cover for the front?
2. Does the stock front cover have a drain plug already?
3. Any other covers you would consider?
3: Lockers
I know the locker in the rear works pretty well, but I have issues with it kicking out because I usually dont run ORM. I like the ARB style air locker and good excuse to put air on the truck
Questions about Lockers
1. Can I get an ARB air locker for both front and rear?
2. Can I get an ARB locker with the gears changed out to 4.88 or 5.13?
3. Any down side to running an ARB locker because maybe its not rated for high speed?
Other questions I have about things related
1. Is the front end a 8.8, 31 spline, reverse diff?
1a. Is the rear a 9.75, 31 spline?
2. Any issues on getting 5.13s to fit or would it be a hassle to mess with so stay to 4.88s.
3. I know guys with the torsen front ends are having problems eating the CVs and IWEs up faster than us 2010 or 2011 guys. I'm hoping with an ARB locker up front that this will help keep torque all the way across the axle rather than all on one side or the other. Also, When I would have to switch on a ARB locker I know its probably going to be low speed and if I need to get crazy I know theres a higher chance to grenade the front end or I can unlock it.
4. The ARB locker will make it easier for me to run with out ORM and locked up the rear.
Thanks again! I know its long and I've been freaking dreaming about trucks and gears for the last 3-4 nights. I can't make it stop so I'm hoping to get some help.
I'll post up my ratios with RPMS and speeds that I posted in 4.56? gear thread and then add 5.13s. I know some of if not all my questions will be answered Tuesday but really would like the input from some guys who know more than me.
I'm sure I'll add more so I'll time stamp it and add it.
