FOX 2.5 IFP Spring combination

Given the OP's situation, I'd call JKS and discuss your issue.

Mixing and matching shocks and springs is always a crapshoot. Damping rates and spring rates need to match up somewhat close. The other alternative is to get adjustable shocks and tune them in situ.

I appreciate it.

Try again.

My bad. Learned something new.

I am currently running exactly what you’re looking for. I have those exact shocks from Jks on 2.5 Metalcloak springs and it’s one of the best riding vehicles I’ve been in and this is a Jeep. Obviously it’s nothing like super high end cars like a Bentleys ride quality but this Jeep rides incredible and has some decent flex with these shocks being the limit at 10 inches of travel. (27 inches fully extended so no need for new DS) If you go with springs from Jks I imagine the ride quality will be similar but Jks uses a far lower spring rate than MC and even stock. I believe Jks front springs are around 125 and stock is about 130 and the rears are 130 for Jks and about 180 stock, so far lower. I originally had the Jks 1.5 inch springs on these shocks are there was no room for travel as the shock body was too long and didn’t allow for enough shock shaft for comfortable travel. With my 2.5 MC springs I have the perfect amount of travel that these shocks were built for so make sure you to 2.5 regardless of company. I would go MC just because I know from experience I love how my Jeep rides but I don’t think you’d go wrong sticking with Jks just maybe look at the HD springs that rate was in the 230’s for the rears if I remember correctly. MC doesn’t disclose spring rate but I believe it’s around the 200’s give or take 20 for back vs front.

Using 2 inch bumps front and rear for both sets of springs I went from bottoming out just backing out of my driveway to hitting speedbumps and barely noticing they're there. Also you can see Jks rear springs at 136 spring rate why would anyone ever make rears that low of a rate that’s where most people put gear, groceries, luggage, and rear passengers sit right there on the springs a small human would start to affect your ride height. It’s not a major deal but still at least match the factory rates right?

Sorry to dredge this up, but which shocks exactly? I only see piggyback shocks or the Fox 2.0 on their site now.

I run the same shock with synergy 3" spring in front and MOPAR lift springs in the rear. Rides great . I got mine from North Ridge

They may ride better with other springs but are meant for the Mopar 2” lift. JKS has these shocks that Mopar wouldn’t sell separately apart from the lift for whatever reason, so may be they have the springs. I’m putting on a 3.5 MetalCloak on my boys jeep right now…replacing the Mopar lift. You can have those springs if you want. Just pay for shipping. Rides great. I actually bought those same shocks 6 months ago and then we decided to go bigger. I won’t give those away since I just paid 1k for them. I’ll take $500 if anyone is interested.

Warning…going to 37s opens up a whole lot of other things. Driveshafts, gears, all the way to the spare tire holder and on and on
