Minor technical correction: the linear spring rate increases force linearly meaning it will take more force each inch your press. The formula for a linear spring is Force = Spring rate X compression distance. And the progressive spring really looks more like a two rate spring than a true progressive. Essentially the spring has two sections one wound tighter than the other, as the tighter section binds it forces the spring to only compress using a smaller section of spring making it increase force higher than a linear amount.
This is super useful for me personally, come springtime (no pun intended) I'm ordering a 2 door rubicon, and am looking to do a very similar build to this one. I have also noticed the same thing while looking up parts that finding things for the 2 door is a lot more difficult, which sucks, because while I get the appeal of the four door, it's length definitely makes it a compromise in off road maneuverability.
Hey everyone…. You guys have to give old Fred a thumbs up, if you watch it, like it!!! We need this content to keep coming and this helps Fred out!!!! LIKE LIKE LIKE LIKE!!!!!! BTW: thanks for content Fred! Watch your channel and Dave’s every day!
Hopefully you enjoy the Synergy coils. I've been running them in my JL for the past 2 years, and they've been fantastic... but I only do 1/3 of the stuff you tackle lol 😆
We actually just put a mopar 2" lift that was on our JLU for about 8 months and stuck it on the JL over the weekend. It is definitely a little stiffer ride, but not terrible. We have considered changing them out ao good to see someone else having the same thoughts.
I currently have the Mopar 2 inch on my JL. It's worked great. After taking out the rear seat, I have a storage system and tools I carry around alot in the back. I'm getting a little sag in the back. I'd like to stiffen it up. I had hoped I could use JLU Mopar rear springs but best I could tell, it's all the same. Maybe the brand you found is my answer, or maybe a spacer?
I had a company make coil springs for my JK pickup, they specialized in handicap vans and limousines. Got the height and load capacity without guessing. Maybe something to look at in the future
I don’t get why the JK never got fenders like those. I love the stock look but want them mounted higher like the quadratec ones. The Mopar high tops are ridiculously expensive so I don’t even consider those an option
i was just thinking about coil springs!!!! I have a stock gladiator sport, want to level it or give a small 2" lift. Id rather get longer springs than spacers.
hey fred have you had issues with progressive metal cloak springs making noise when u compress it fast? almost like there might be the metal binding against the coil itself. 15 jku 3.5 metal cloak lift

The different spring rate/length is for the gas tank to reduce the 'JK lean' of old.
Baxter doesn’t seem to be interested in working today. Looks like he’d rather hang out on Dad’s lap.
Thanks Fred that was extremely helpful. I know what to consider now when buying my springs.
Rugged ridge also makes high-like fenders which look stock but offer a lot more clearance and LED light strip.

I just posted this video up on JLforum!
AEV 2.5 inch for a 2dr, corner specific, triple rate, frequency tuned, just shy of 3 inches with bumpers and all the add ons.
I plan to go Old Man Emu springs in my 2 door JL.

Great information. Very helpful. Thanks Fred
Love the channel Fred!
Yeah, and even some ‘big’ companies don’t offer corner specific coils which are 100% needed 😒

Quadratec has a stock looking fender that’s taller than even the rubicon fender and uses the stock marker lights

I had no idea they separated the springs out in that configuration
did baxter eat the whole wheel of cheese?! i'm not even angry, i'm impressed!

Wow alot of information brother
Thank you.
thanks for the vid. have you seen the Rancho 2 door specific coils yet? i'm considering those as the current ones i'm running are way too harsh.
They sell retaining kits for the rear springs so they don't pop out.
hey fred have you had issues with progressive metal cloak springs making noise when u compress it fast? almost like there might be the metal binding against the coil itself. 15 jku 3.5 metal cloak lift
twist torque.
Baxter is like less talk more work lol .
smallest market? look for something for a gen 1 Kia Sportage!
If you wanted the perfect coil, you should’ve went with an airbag…
Salute on another great video
daves already shown his safety check in. your falling behind
Geez JL’s are hella lame lol!
