I went with Fox 2.0 shocks and stabilizers on my 2005 Ram and I wish I hadn't. They only lasted 30,000 miles before the seals started failing. Sent them in to be rebuilt and they responded saying it's going to cost more because the shafts are pitted. I told them to just get them done as my truck is just sitting here useless but never again. Will go with King next time.

[@CJCOffRoad]

You didn't mention tire size or type, but my guess would be that you're running commercial tires on a 22.5 wheel set up. Those tires ride horribly and no suspension can ever make up for it sadly. You also have to remember that this suspension is designed to ride nice AND tow. It will never ride like a 1500 truck unless you completely give up your towing ability, so you'll always have some sacrifice. If you still aren't happy though, talk to Thuren about making some changes to your shock tuning!

Just purchased a 2019 Ram 1500 2wd new body style and I plan to put on a 2.5 front leveling kit with 35x12.5 tires on 18x9 wheels! Does anyone have any knowledge as to if this would cause any rubbing? If so what can be done to combat that issue? Also, will I absolutely need to purchase new control arms? And why? (First time truck buyer & first time dealing with large wheels/tires and any type of leveling kit)

[@RucaMad]

I have a 19 Ram 1500 4WD, and also have 35" tires on a 18x9 Rim. The tires will fit and only minor plastic trimming is required. New UCAs are mainly required if you lift beyond 3" in the front. New UCAs are a benefit for better angles if you can afford them, but not necessary at 2.5".

My question is with the 295 tire being a 35.1 tire x 11.6 wide vs the 37 which is really a 36.5 x12.5...with less mass wont it ride and handle better. Second Q..Any more info on lead time for the gas superduty components vs me having to use the diesel components.

[@CJCOffRoad]

If you're debating on tires, always go for the bigger size. I can count the number of customers who downsize on one hand, but almost everyone that goes for a smaller size up front comes back for bigger in the end. That truck will handle 37s just fine! As for lead time, expect about 4 months. This whole COVID-19 thing is going to throw a wrench in the supply chain though.

All the fox shocks are nitrogen charged, but you can’t use that to adjust them. We promise that thanks to Carli’s custom tuning, you will have zero need for changing anything.

[@toHelluRide]

Would I be a fool to buy a diesel for daily driving / commuting and probably never tow?

[@CJCOffRoad]

Absolutely not. They’re great trucks and comfortable daily drivers. The only catch is that the modern emissions trucks need some highway time with each drive cycle to burn off the soot in the DPF. If you only have a 5 minute city commute, a diesel truck isn’t the best choice.

I have a 06 dodge mega cab with 5.9 and I’m interested in the 6” lift but on the fence whether the long arm or radius arm. One question is what about traction bars in the back? Do you run those?

[@CJCOffRoad]

We never run traction bars since they defeat the articulation and ride quality improvement that the performance leaf springs give. We’ve got plenty of customers running high power on Carli or Thuren leaf springs without issue! As for the arms, the 6” carli systems require the Carli radius arms, so that makes the choice easy!

I see Carli has a 3.25 in Lift for the 3500 Air-Assist trucks. This kit is just too much for what I want to do with the truck. I would be extremely interested in just a leveling kit for my 2018 3500 Air-Assist SRW. Something along the lines of; Front Coils, Trackbar, Sway bar, Radius Arm drop brackets, tuned Fox 2.0's all around and then for the rear, I would be more than satisfied with just a block for the airbag and a block for the leaf pack.

[@CJCOffRoad]

That kit would work fine! We typically recommend either the lower height Thuren front coils for that, or the Thuren air adjust rods in the rear to get that level height. Give us a call and we’ll get you set up!

Love the Q&A session where you are just shooting from the hip. Heres a question that might fit a future episode. I have a bone stock 2017 F350... i have a set of 17” methods that i have owned since i picked it up but just now considering suspension and tires. I tow a 10k toy hauler to go kart tracks all over the PNW (lots of towing hill and mountain passes). Whats your general recommendation regarding lift&tire size for guys that tow like me?

[@CJCOffRoad]

Since you tow, you can either do a 35, or re-gear for 37s. As for suspension, a Carli level or a 4.5” system with the Carli LT bags would be perfect. We’ll address that topic in a future Q&A though because it’s a common situation!

[@CJCOffRoad]

Your best bet is to swap out that lift for a 3” Carli or Thuren set up, and then change your wheels and tires so you have more sidewall. A 20” wheel with a 37” tire still has a great modern look, but will ride night and day better!

[@CJCOffRoad]

Realistically they're the same performance wise. Both are top level brands, so what matters is the tuning inside. An untuned shock isn't going to ride well at all, so having something like these Carli custom spec and tuned King shocks is what matters, and Carli simply chose to work with King since they were willing to do the custom tweaks to length, pistons and shim tuning that Carli needed.

[@JOHNWAYNE1920]

Maintenance wouldn't be required if they'd just make the body aluminum or stainless. Companies can't make an entire truck out of aluminum or stainless, it's a stupid analogy. For what King shocks cost there is zero excuse for using cheap steal. Call it like it is.

[@CJCOffRoad]

Actually maintenance is the exact reason that King uses a steel body. An aluminum body doesn't hold up as well as a steel shock body to the heat and wear generated in thousands of miles of heavy off road use. King has the option to use any material they want, but they choose steel because of its strength and wear resistance in punishing off road conditions.

[@JOHNWAYNE1920]

@@CJCOffRoad I'm certainly no expert on shocks but they do use aluminum in space shuttles, engine blocks, heads, wheels, etc etc. I can't help but feel it goes back to cost. Otherwise all else being equal stainless would be the obvious choice. Then it becomes a question of buying a name vs. Quality. I have no problem paying top price but I want the best built, not the most popular name. Irony is I was sold on your king set up before this video but now I'm leaning towards the fox.
