    Chrysler 9.25 differential grease mesh pattern

    I got a new ring and pinion for Chrysler 9.25, I know how to set backlash by adjusting the two threaded inserts on the sides and setting backlash to .006-.010” of play, the other measurement is pinion depth which is determined by shims, I keep playing with the system and setting it up and...

    3.92 Detroit trutrac LSD

    Thinking about having one installed in my 2010 “5” speed. Most of my driving is in town with hills and I’m geared high now but not sure what ratio. 3.23 maybe? Hit ~55mph before shifting out of first WOT. Anyone made this change and have any regrets about it??? How’s mileage changed? Also...

    3.92 Rear Axle Swap

    Good Morning Everyone, I have a 2004 Ram 1500 4x4 with the 3.92 ratio. My son was driving the truck at the time and didn't realize that it was leaking from the rear seal and in time, heated up the housing and stripped the ring/pinion gear. I replaced the gears and seals, but there was a small...

    3.22 Gear Swap to 3.92 Grocery List

    Here's the story: I'm currently running 35s on my 6in lift but want to upgrade to 37s.. My main concern is power loss and serious trans wear with adding the 37s.. my 35s weigh 69 lbs and the 37s I'm looking at are between 75-80 lbs, I doubt its a good idea to keep the 3.22s with the additional...

    2013 5.7 a big hog

    So last month the wife and I traded in our 2016 Ford Fusion 2.0 Ecoboost for a new 2018 Ram 1500 quad cab 4x4 with 3.21 rear end and 5.7 Hemi. The price was too good to pass up! We put 275/65r20 toyos which is about 34' one two weeks ago and have yet to calibrate the speedo and no mods. We have...

    I'm looking to trade my 2016 Ram 2500 Laramie blacked out Megacab 4x4 6.4 hemi for a 2019 Ram 1500 Laramie 4x4 with the 6 ft 4 bed and bench seat in front. The longer beds are very difficult to find at least in Texas and only about half of the Laramies have split bench seat. I want to be able to...
