Heavy Duty Shocks On A 2023 2500

[joesstripclub]

I have done 48-50 on the rear and 58-60 on the front. Was not sure how low I could go on the front with the V8. Used to a diesel up there. Drove 80 miles today and will try the lower pressure on the front and the rears. Pogo stick is a good analogy. I plan to do some research and find out if there IS a difference in the Koni vs Bilsteins. Might have to pony up some more bucks and change those out. Then hope it makes a difference.

Unloaded you can go much lower. Definitely want to increase pressure if you are towing. Check out this pdf from Toyo Tire: https://www.toyotires.com/media/3729/application_of_load_inflation_tables_20200723.pdf. Check your own tire size on there to verify load rating by pressure level. Look towards the back around page 25. My 285/70/17 tires can hold 2640 lbs each at 45 psi and 2430 lbs at 40 psi. Thats plenty for just driving around town for me. I'd definitely try dropping your pressure more before you spend big bucks on new shocks.

Good tire info. And E rated vs D rated, etc. I'm pretty sure the tire brand and sidewall height/ply have something to do with the ride. I'm not doing anything other than lowering the pressure until I get the camper shell on. I don't know the weight but I would guess at least a couple hundred pounds. That should help a little. Drove 80 miles yesterday with it and even on smooth portions the small bumps pogo. Pretty sure it's the shocks but have not done the research yet.

I was able to crawl under the truck and get part numbers off the shocks and then try to research them. Initially not able to determine if the shocks were 4600 series or 5100. The part numbers only took me to seller sites. But one had a video that might explain it. The 4600 are blue and yellow, like mine, and the 5100 heavy duty are grey. Those are usually installed on lifted trucks. So unless the Fox brand dampen the ride a bit better on the ripples and pot holes in our roads my back and teeth are just going to have to get used to the ride. Looking forward to having some weight in the back to help. It's also really hard to change settings on the computer screen while driving. Kinda like Whack A Mole trying to adjust temps, music, nav, etc. Buttons and knobs were much easier. But I'm just old school and grumpy.

The 5100 will fit on standard height truck, I had a set of 5100 on my stock 2006 4x4 2500 CTD much better then the factory 4600

My 04.5 CTD rides better than the new truck. And it has leaf springs in the rear. The 2014 3500 I had was also a CTD but rode about like the 2023 and it had leafs. Understandable with that one and the payload. Have no idea what shock was on those two originally. The new truck handles well and in some ways very comfortable ride when on good roads. Corners well too. Better than the other two. Just has that pogo stick action on bumps. Lowering tire pressure more tomorrow. It will be interesting when I tow the travel trailer with inflated tires and 6-7000 LBS behind me. Might smooth the ride out just fine and make sense why these shocks were installed.

Got the new 2 1/2 to 2 inch hitch reducer in the mail. My Class 5 hitch in the 3500 came with the reducer in the truck. Seems RAM could not afford to give me one in this truck. We looked in the sales lot at other trucks with a Class 5 and they did not have one either.
