RAM 2500

I'm currently towing with a RAM 1500/5.7, and considering trading for a 2500. My needs don't really require a diesel so I'm looking at one of the two gas engines available. I think either of these engines in a 2500 chassis would be an improvement over my 1500 just because of rear gear ratio. ( 3.51 in my 1500, 3.73 in the 2500 )

My question is there a noticeable performance difference between the 5.7 and 6.4 when towing ?

    Nice looking truck for a tiny bed though.

    Just curious, what are your beefy man springs rated for on your Ford Superduty? My "fake truck" coils are rated at 6500 lbs... I would be willing to bet that my coil springs are rated higher than you leaf springs and I have a higher tow rating...


    If your so curious perhaps he prefers the reliability of his leafs and never had a problem from them! Everyone is entitled to their opinion.

  • I'm @ 60K on my 2014 6.4 Hemi, 3.73 gears and tow an 11K 5th wheel. I'd say the truck is good not great.

    While towing - Gear ratios in the tranny are borrowed from the diesel and pretty much suck for this truck. Also, the tranny has some really annoying/stupid shifting behaviors. Most of that can be worked out with manual shifting. The ratios really leave a large gap between first and second. You are often stuck in no man's land trying to go 30-40 up a steep/winding hill. The tranny drops into 2nd but quickly slams back up into 1st.

    I know I'm pushing the upper limits of the truck and have the less ideal gears. Even with my complaints it's not like I don't eventually get where I'm going or I just hate the whole experience. It just could be better. If starting from scratch I'd sure be looking long and hard at the Ford 6.2 with 4.30 gears (and presumably a tranny that wasn't designed by an intern).

    As a daily driver the truck is near perfect. Also, Ram does give you more for your hard earned money than the competition so it's a tough call. If I towed more frequently, and at the weight I'm towing, there's no way I'd keep this truck.

  • I had a '14 Ram 2500 with the 5.7l. Apart from numerous problems, I hated driving and towing with it. The transmission mated with the 3.73s was terrible. It was always in the wrong gear and would get bogged down. I ended up trading it for a new 6.7 CTD.

    The 6.4 has slightly more power, gets better mpg because of the cylinder deactivation (5.7 doesn't have it) and has 800+lbs more payload. If you want gas, go with the 6.4. I'm not sure if they share the same tranny but I have heard the same complaints for both.
  • The 6.4L not only makes more peak power, but it has quite a bit more power at lower RPMs when compared directly to the 5.7L. It's not all about peak power.

    Yup, the 2500 probably weighs an additional 1500 lbs over the 1500. The 5.7 will feel more sluggish in the heavier truck. The 6.4 would probably feel about the same in the 2500 as the 5.7 feels in the 1500.
  • I traded up from a 1500 to a 2500, and from the 5.7 to the 6.4 ... kept the same trailer. I don't feel any extra "power" from the 6.4, it still takes a while to get up to highway speed, or going from a stop.

    I've never seen a 2500 or 3500 in these parts with the 5.7, always the 6.4 or CTD.

    Get a taller rear end, unless this is a daily driver too? Loved the 3.92 in my 1500, and the 4.10 in my 2500.
  • I think the 5.7s generally ship with 17" wheels and tires so the axle ratings are lower. That's probably why the GVWR is lower also. It's something you could always fix later I suppose. Bigger problem might be finding any 5.7 trucks - darn near all gas Rams ship with the 6.4 outside of some regular cab work type models.
  • The 5.7 will have a lower GVWR than the 6.4 truck, resulting in about 1000 lbs less payload. The 6.4 gives you 27 more HP and 29 more ft/lbs of torque. I've never met anyone that didn't want an additional 30 HP and torque under factory warranty!

    Either engine are good engines though. If the 5.7 meets your needs, its a solid and dependable engine that should be available for a lower price.
