Shocks are actually more important than the springs! EDIT: They are equally important in the suspension package, but in our particular bottoming saga, I feel it's the shocks.

I've made 3 different spring swaps (Evo 120ish lb, 3.5 Clayton Gas 188lb, 3.5 Clayton Diesel 216lb) and the bottoming continued until the shocks were properly valved for enough mid speed damping to control the weight. Even the added Fox hydraulic bumps weren't enough alone to damp the bottoming.......

I've also had 3 different shocks with dozens of different calibrations installed! Premium shocks like Fox 2.5 Elites did not make much difference until I added the mid speed valving changes.

I think most manufacturers if not all are using a "If it fits, it ships" philosophy in this regard.

Well sounds like I may be one of the first test cases for the King shocks. Will let you know once the lift is on and have time to test it out.

The internal valving on our Eco Diesel fitment shocks for both JL and JT is in fact different front and rear, especially so in the front. Without getting into deep details the valve shim stack on the front shocks is valved to be slightly faster reacting, and a bit more on the firm side to help control and stabilize the Jeep with the extra weight of the engine. Also, the fitment is specific too, for the front shocks have a physically shorter reservoir/piggyback to clear the aux battery and washer fluid bottle. The rear shocks are tweaked in length to help ensure clearance for the DEF tank.
So what is the part number for diesel non resivour shocks

Great question. There is actually quite a few different part numbers (12 to be exact) depending on the version of shock and then the corresponding lift amount. I'll try to outline the numbers the best I can. These part numbers will be for complete sets of 4 shocks. Most of these numbers should be live on our website, or many of our dealer's websites.

Falcon 3.1 Piggyback shocks.

  • 0–1.5” Lift - 14-02-31-400-002
  • 2–3” Lift – 14-02-31-400-152
  • 3.5–4.5” Lift – 14-02-31-400-202

Falcon 3.3 Piggyback shocks.

  • 0–1.5” Lift – 14-02-33-400-002
  • 2–3” Lift – 14-02-33-400-152
  • 3.5–4.5” Lift - 14-02-33-400-202

Falcon 3.5 aDapt Piggyback shocks

  • 0–1.5” Lift – 14-04-35-400-002
  • 2–3” Lift – 14-04-35-400-152
  • 3.5–4.5” Lift – 14-04-35-400-202

Falcon 3.5 E-Adjust Piggyback shocks

  • 0–1.5” Lift – 14-03-35-400-002
  • 2–3” Lift – 14-03-35-400-152
  • 3.5–4.5” Lift –14-03-35-400-202

I'm glad to read here that you guys went an extra step for the diesel models.

However........the Epic video I posted farther up the thread clearly shows how uncontrolled his truck is and that whole Canadian group running your shocks have vehicles that act much the same?

Not trying to be a smartass here because I'm the newcomer in the game. Maybe I just like a weird controlled ride?

Ty.... are these generic or can I select diesel vs gas

What about the 2.1 mono tubes 4" lift, piggyback too rich for my blood

The Eco Diesel shocks fit on gas models no problem, and are actually the required fitment spec for 392 and 4Xe JL's. Best way to look at it is the diesel shocks work on all models, but the normal "gas" shocks do not. The 2.1 Monotubes do not have a Eco Diesel change, all 2.1 Falcon shocks work and bolt on to all models.

What I actually meant was is there a gas or diesel option for each, the websites for eBay of them don't clearly define the application.... I I'm down to assuming if it doesn't say diesel, it's gas since the MFR's can't seem to annotate that it's gas only...

Ok so bottom line the 2.1 are not for the diesel

I would politely disagree. The Falcon 2.1 Monotubes use a vastly different valve shim stack compared to the 3.1/3.3/3.5 series shocks due to the "lack" of the piggyback on the 2.1's. We found during testing that the existing tuning on the 2.1's reacted and worked well with the Eco Diesel as is, and as a result all Teraflex Falcon and ReadyLift Falcon 2.1 shocks retained the same valving. We currently have 2 Teraflex company Eco Diesel Jeeps with the 2.1 Monotubes installed on them and they both ride and perform great as expected.

This is back to the clarity issue, from your statement I took that to mean that the "2.1 do not have an ecodiesel change" and that all shocks bolt on, which is true in all cases of all shocks really since the frame and axles are identicle...

"The 2.1 Monotubes do not have a Eco Diesel change, all 2.1 Falcon shocks work and bolt on to all models."

The eco diesel is 400 lbs heavier than gas, seems to me that if the 2.1 is an acceptable (non bottoming out shock) on the diesel JT, then is must be stiff as shit on a gas JT....

So 2.1 are back on the table, now just need to find them for a 4" lift

Too late...already have them and getting installed this week. Ordered them from EVO, but there is always the option to have them re-valved from them as well if needed.
The Evo spec Kings I thought were way too soft for a light truck and my client loaded a bunch of other shtuff on like a camper shell, Decked system, every piece of armor you could buy, and a RTT.

When we were considering buying a JT, I took my wife along on a roadtest. She immediatly told me "No way if our truck will be this wobbly.....I'll get carsick!"

Hopefully you like them.
