Best coil springs for jeep jk

I have a 2013 JKU sport. I have done a lot of research and searched a ton. I have found a lot of info I'm looking for. I wish I could afford to buy the teraflex Prerunner kit but I can't.

I don't want anymore than 2.5" lift. Especially because all of the 2.5" kits out there will provide me with more than 2.5". I am not going to run any heavy aftermarket parts like armor/bumpers/winch. I will be keeping stock arms and will use AEV front control arm drop brackets. Of course there will be other mods to the suspension and such. I plan to run the set of fox shocks that Teraflex offers and their 2.5" speedbumps kit. I am trying to go "big" with my build while not spending money on the things I don't feel like I need such as control arms. I'm a fan of the control arm drop brackets because they'll correct the angle of the CA's back to stock/parallel to the deck. I'll be running 33's most likely. I know I could fit 35's with a 2.5" lift. But if you know what you're doing you can do a lot with 33's but it really comes down to price and not buying after market wheels or spacers. I am going to run 255/75R16 KM2's on stock steel wheels (33x10.50) I'd run a set of 35" treadwrights if I didnt need spacers or new wheels.

I prefer the trails in AK where I came from, but I LOVE wheelin' fast! I have recently moved to San Diego (Coast Guard) and have found some wheeling spots with my GF. Of course there's plenty down here if I want to drive, which I will. It's likely I'll move back to AK soon and this rig will be wheeled in AK.

So my question is about the various 2.5" springs available. They will be bought as a set (all 4).

I have researched Teraflex, Rock Krawler and Metal Cloak. I was recently set on the 2.5" RK stock mod system. Whatever I get (such as the 2.5" stock mod) will be the starting point of my build, but I'll be adding a lot from there. Then I did some reading on MetalCloak springs. A member on here bluewave said in a thread that he really liked how the metalcloak suspension rode and was a better compromise between crawling/go fast stuff. And he did a pretty good job comparing apples to apples. The MetalCloak stuff seems to not only ride better (???) but is designed for more up-travel. The MC stuff is a little more expensive though.

So that's where I am. I'm all about doing my research and buying these expensive parts once. Even though I already bought a set of OEM 19/60's. I imagine I'd be happy with RK, they get great reviews and people really seem to like how their springs ride. But the Metal Cloak 2.5" progressive rate springs might be closer to what I'm looking for. What do you guys think??

almost forgot about Synergy. Seeing they're progressive these were the first coils I looked at.

I even emailed to ask about actual lift height since I wasn't running aftermarket stuff all over my rig.

Price for all 4 is nearly identical with MC. Your answer will be biased I'm sure, but do you think your synergy coils would perform better for my situation? With what I have described would you recommend the 4-door 2" coils front/rear. I'm assuming I'll get more than 2" lift with my stock rig/no heavy stuff.

ALSO: What fox shocks would you recommend? If I run the 2.0 IFP Fox shocks I would spend less money than what I was thinking. I don't know that I need remote res. Are all the shocks on your site priced per each shock?

Our springs will give around an inch more lift than advertised on a stock JK. The ride is very good though, both on road and off road, especially when paired with quality shocks like the Fox IFP shocks. We have this same setup on our 2012 JKU at the moment. On our site the shocks are shown individually at retail pricing. You should be able to get a better deal through any of the vendors here who sell Fox though.

I'll second the poly springs. They're nice and supple over small chop/washboard, and do firm up as they compress.

More importantly than new coils though, if you're planing on going fast, is going to be GOOD shocks. I'd say rather than buying the 2.0 ifp shocks, save your money and buy a good 2.5" rebuildable shock Fox/King/Icon/Bilstein - pick your favorite color, but having the ability to open the shocks and adjust the valving will be of great benefit to you. Not to mention the added oil capacity of a 2.5 with reservoir over a 2.0 will help fight fade when you're out blasting sand washes or hitting whoop sections. Another option is a shock with the compression adjusters like King and others now offer. Allows you to make incremental compression adjustment without opening the shocks. OR you could really do it right and go with a bypass. It's all about how much you're willing to spend... A bit of planning might help avoid you spending the money twice in the long run though.

The guys at POLY can help get you pointed in the right direction... Shipping is always super fast too!

Sir Thank you for considering RK for your build needs.

Our 2.5 coils mid December will have transitioned to Triple Rates to match our 1.5 and 3.5 coils. We feel this coil design is the best overall design for all applications. They have improved ride quality and handling for street use, improved suspension travel for high articulation demands, but the main thing we were after was more fun in the sand and the whoops. These coils do it all very well without compromise. It took us a long time to develop them and now they are finally ready to go!

Let us know if you have any questions.

Oh my! The damn free market brings so much competition and choices. I don't do well with choices!

These new RK springs sound interesting, but I'd like to see reviews once guys are running them.

I'd like to keep hearing input on which coils would be best for fast trails. I'm not trying to complete, I won't have a cage or harnesses. So my other question is what shock would you guys recommend? I was looking at the Fox 2.0 IFP shocks because of some good reviews, their name (being honest) and reasonable price. Any others I should look at?

If you plan on running high speed stuff, I have always heard you pretty much need to get remote res shocks, even good standard shocks will overheat at high speed.

If your just gonna run 33's I wouldn't even bother with a lift. It sounds like you have some 4dr springs and I assume your have a 2dr Jeep, that will probably give you an inch or so. Then either trim your fenders for up travel clearance, or add 1" bump stops. Might want to look at the Sumo springs MC has on their site, or one of the many air bump kits if they can be setup for stock height to 1" of lift.

I think if you put the AEV drop brackets on with only 33" tires your actually gonna lose ground clearance VS keeping the stock lift and tires.

For you application, we would recommend Remote Ressy's for sure. IFP's will pack pretty hard (like a dirt bike fork) and not cool as well as you are going to need. Even 2.0's can be a little small for JK's. 2.5 or 2 5/8's might be the way to go with Remote Ressy's…

No worries on the reviews for the coils. There are a few sets running around already, but certainly not everywhere. We know Marcus at River City has a few customers out there already on them as far as the 1.5 coils are concerned.

Thanks a lot to everyone for the replies and input on this. I think I'll run the remote reservoir Fox shock "kit" from Teraflex. As soon as you get into 2.5's price goes way up.

Still undecided on the coils. I should be able to start purchasing my parts after the new year. I've got some debt getting paid off and I recently got advanced to my next rank, and I'm selling my GSXR 750.......so soon its GAME ON for the JK.

Also I haven't email teraflex about this yet, but they dont offer any real details on those shocks http://www.teraflex.biz/jk-fox-shock-absorbers-set-of-4.html#first

I have to guess they're 2.0's by the price.

The difference in performance between a 2.0 and 2.5 is pretty significant. Splurge on the 2.5s, and you'll be happy you did. I couldn't believe the difference when I went from a 2.0 to a 2.5 on the rear of my desert truck... I used to boil the 2.0s, get so hot they'd go through seals very quickly and burn up the oil. 2.5s will provide much more dampening for your jk, these things are heavy. Once you start adding compression valving to a 2.0 then you're really going to fade them quickly. If you're in SD look up Off Road Warehouse. They are local (3 locations I think) and will get you/recommend the best setup if you plan to mash around ocotillo/borrego/baja etc. Spend the money once, and skip the 2.0s, you wont regret it!

Heavily considering upgrading my current 2.5" dual rate coils to the new iteration...

I currently have the heaviest duty OEM springs installed in the rear (60's) and have the heaviest front coils (19's) ready to go into the front. It was mentioned not to bother with a lift since I'm running 33's. Any thoughts on sticking with mostly stock suspension setup and spending my money on really nice shocks and bump stops? I thought it would be beneficial to run some lift for more up travel.

After installing coils I found the 3 limiting factors for axle droop were brake lines, track bar and shocks. So those areas will be addressed regardless of lift. I will also run extended sway bar end links in the rear and sway bar disconnects in the front.

EDIT: Do you guys know if these King bumps install in the stock location like the TF speedbumps? Are they $495 for the pair!? http://www.polyperformance.com/shop...nt-2.0-Bump-Stops-for-07-Jeep-JK-p-31118.html Nevermind. I finally found the answer. They do install just like teraflex speedbumps in the stock location. These are nicely priced!

And are these sold in pairs? http://www.polyperformance.com/shop/King-OEM-Replacement-Shocks-for-Jeep-Vehicles-p-29219.html
