And @thevikingWith the 5.13 they are aam?
How does your truck get down the highway st say 70-75 mph
Any info on this gear set and how your truck operates would be awesome
Like fuel mileage
Rpm at certain speeds etc
The shop i found to do it was right at 3k for everything
Gear ratio didn't seem to effect the price
Thank you for any info
I'm hoping to fo this soon and doing all the research i can
I'm thinking 5.13 that 6.4 is a beast
I also have 35 tires
Huge post but I know how long and far I searched for info before and if this helps, awesome.
AAM Part number for the 5.13 gear set, 9.25 front differential is #40136007 and rear 11.5 is #40030646 (pic shown)
2016 Ram 2500, 6.4 L, 6 Speed, 66k mi
35" (34.5") Mickey Thompson MTs worn to 33.75". I run 91 octane with a Hemifever tune and longtube headers.
Take my gas milage with a grain, I post for informational purposes only, I love to make my truck jump and go. All a Ford has to do is wiggle near me and I am on it. Many trucks see Power Wagon on my tailgate and they come flying after me, I show em full throttle in any gear and they stay back and don't even try, no shizzle.
I did the regear for 37" tires, I'm enjoying the experience with 35s so much I haven't bothered with the 37s yet.
Traffic flys out here, 85mph in a posted work zone will keep you alive but not unharassed in the left. My truck handles the crazy high speed no problems.
I drive elevations from 6,700ft to 10,000ft regularly and above 10,000 ft as often as I can.
If I could take my foot out of it who knows what kind of mpg I could get but so far no luck there.
