  1. Starting a 6.4 Hemi swap

    I'll take a look. I run both front and rear Expedition One bumpers on my RM 3500. Edit: I looked. As I would expect, it is a good piece. I feel the replacement tailgate is the better option. 1. I get to lose weight from removing the stock tailgate. 2. The tire sits, what looks to be 6" farther...
  2. Starting a 6.4 Hemi swap

    Making decisions daily! I'm moving up to the 40's and leaving the 5.13's in there for now. I was immediately faced with the spare tire dilema. Good news: The underside of the bed is gonna get a lot cleaner. Bad news: No place to put the spare that doesn't take up bed space or add a ton of...
  3. HYDRO BLUE PEARL Gladiator JT Club

    I just loaded it on the trailer to go to the shop to get a 6.4 Hemi swap
  4. Starting a 6.4 Hemi swap

    I cut out the factory hitch when I bolted on the rear bumper, so there's that. I could build or buy something that runs the hitch point through the bumper to save ground clearance, but first I'll need to figure out which direction I am going to be told I'm going :-( Favoring Patagonia MT's at...
  5. Starting a 6.4 Hemi swap

    Excellent logic Are those 40s you have on your JT? I think I have made a decision regarding this topic, and that is to move to the 40" tires. Simple enough...Since I have real beadlocks, I'll just do the tire swap myself. On the subject of where I might mount that spare, well, that's a different...
  6. Why not Jeep???

    Could not agree more! We purchased a Canyon truck for our boys in 2019. I was shocked at how much power that 3.6 had, and I want to say it had an 8-speed. That truck was totaled. The oldest purchased a Colorado and hasn't looked back. I then purchased a Cadillac XT6 (we like Cadillac). It has...
  7. Starting a 6.4 Hemi swap

    I'm sure you looked at the numbers I posted. It's a wash either way. 5.13 with new 40" tires or new 4.56 with my original 37s. Here's what I am thinking at the moment: Keep the 5.13s and get new 40" tires. It's about the same cost either way, and by going to 40s, I get brand new tires. That...
  8. Snorkel with Hemi swap?

    Good for you! My shop is also a wholesale warehouse and distributor for Mopar stuff. Very likely, they have it all sitting on a shelf, but if not, I can run it awhile with just the airbox
  9. Starting a 6.4 Hemi swap

    I've never driven Pritchett Canyon, but another trail requiring more clearance is the Rubicon. And that one is in my gunsights for this truck. I haven't broken many axles/differentials, comparatively speaking. A 9" Ford once, a 10-bolt once, well, a 9" twice now that I think about it. A Toyota...
  10. Starting a 6.4 Hemi swap

    Not really trying to do anything specific except to make the best decision possible. The shop doing my Hemi swap suggested my 5.13's were too steep and recommended a 4.56. Cost $2399 for new ring and pinions. That got me thinking it might be a better choice to go with bigger tires. I'll drive...
  11. Why not Jeep???

    Side-tracking my own thread! When you get there, you will be flabbergasted at the power of the Cummins Ram. My 3500 dually feels as light as a feather. I barely touch the throttle, and it blasts away. Mine is the HO with 1075 ft/lb and 4.10 gears pushing 35" tires. It will spin the four rear...
  12. Starting a 6.4 Hemi swap

    I am relooking the gear ratio thing. Look at the following numbers: 5.13 40.0" 70mph 2000rpm 5.13 39.5" 70mph 2050rpm 4.56 37.0" 70mph 1950rpm 4.56 36.5" 70mph 1970rpm 5.13 39.5" 75mph 2200rpm 4.56 36.5" 75mph 2100rpm I...
  13. Starting a 6.4 Hemi swap

    Concur- It is very likely AMW could tune for more. Heck, I could have 550 HP, but with my rooftop tent configuration, your 505 HP would leave me in the dust. It's all relative, and no one ever could tell the difference of 25HP in a 2.5-ton vehicle. Going from less than 300HP (212 at the wheel)...
  14. Starting a 6.4 Hemi swap

    Same engine. AMW claims 505 HP, but SRT claims 485 HP. I'm going with the factory numbers. Now, having said that, on a 93 octane or E85 tune, I'll bet most folks who tune could pull 505 out of that engine. In all likelihood, your engine is 485, but who really cares? What's 20 Horsepower when...
  15. Starting a 6.4 Hemi swap

    I like it!
  16. Starting a 6.4 Hemi swap

    I think I might start another 6.4 Hemi swap thread when we actually get going. This one is, what, 5 pages long with chit-chat and growing by the day. Chatting it up is good, but to better focus on the actual swap information, either I make a note of where the "good stuff" starts, or I start...
  17. Starting a 6.4 Hemi swap

    Oh man! That's no fun. Well, at least you get to burn your hands and skin a knuckle or two getting in there. You have that to look forward to! ;-)
  18. Starting a 6.4 Hemi swap

    For sure north of $30K I explored Jeep Speed Shop, which has a sort of recipe of parts to get a Hemi in there, but I did not like it. The intake thing alone, then how and where to get all those parts, and...
  19. Starting a 6.4 Hemi swap

    I have not had the opportunity to talk to the owner about this subject, as I wanted to. My Jeep is their test mule, so I am seeing a substantial benefit. I do remember, way back when, he was talking around $32,xxx + labor, but I believe the final numbers have not been settled. This swap is not...
  20. Why not Jeep???

    I guess that makes sense, the speed part. Heck, when I'd drive from Kandahar air base to a nearby FOB, I'd take one of our Prados and go like hell until I reached the other gate. But I've also been in an Army that used K5 blazers and K20 or K30 trucks, even a W250, which had straight axles. They...
