Best 4" coils.

Right now I am running the RE 3.5" coils and they are very stiff. I am curious as to what yall think are the best 4" coils? Ones that perform well offroad as well. Thanks!

Depends really on what kind of ride you want and if you have any extra weight. I've heard good things from Terra Flex, Rubicon Express, and Rugged Ridge

I've run RE 4.5 coils on my last two rigs and have lifted other rigs with their 3.5 inch kit. I have never found them to be stiff and in fact I believe they ride much better than stock offroad. I think what you may be feeling could be more related to shocks. I always use Bilstein 5100s or Rancho 9000s and they can give you a really nice ride when combined with RE springs.

Does OME have 4" springs for a TJ?! I tried finding some but I remember only finding up to 2.5". The JKs however had the 4" springs available

I have RE 3.5 and like them OK and am considering updating shocks to the Rancho 9000 as the current net price of $57 each after rebate is pretty sweet

LJ dave which specific rancho 9000 shocks did you use with the RE 3.5 springs?

Yes, OME has 4" springs, just not 4" kits. I bought mine at Quadratec for $167 a pair IIRC.

Digger - I have only used the Rancho 9000's with the 4.5 inch springs and I ordered them from a shop that I bought the kit from and took their recommendation on lengths so I don't even remember what lengths they specified for that kit.

I just replaced ProComp springs with Currie. You can see the differences below. The ProComps had 4K miles on them. Both are 4" lift springs.

While it's easy for everyone to throw out their idea of the "best" coil, you need to determine what you are trying to accomplish.

Some coils have a higher spring rate to allow for heavy armor, winch etc. Others have a lower spring rate that allows for less armor.

Understand this...Springs set your vehicle's height and shocks control the ride. So if you think your coils are to blame, it may very well be your shocks! What shocks are you running?

bingo. shocks determine ride for the most part....so take a look at your shock options. on the springs, check out Currie springs for sure, but also look at OME, BDS, Metalcloak and anyone else that has a spring rate and length that works for your needs.

Shorter springs with a higher rate will have more "lift" than longer springs with a lower spring rate. Not to say that the currie springs don't end up higher than your pro comps, just that the comparison of unloaded length really means nothing unless all other factors are exactly equal.

Thanks! I want to switch out my pro Comps really bad and was going to go to Terra flex but you told what I been seeking a while and will probably go to OME

I understand. I was just surprised at the unloaded length difference.

x2

Shock selection is the primary factor for the Jeep's ride.

I replaced my front and rear shocks with Bilsteins and made a huge difference on the ride quality. I currently have Terraflex coils. The original Terraflex nitro shocks were a bit too harsh for my style.
