I'm looking to swap out coils and shocks for a smoother ride and was wondering about synergy coils. Tried to search the forum but couldn't find exactly what I needed. Most of the info was for JKUs. I have a 2dr and was wondering if anyone else here has ran the 2" progressive coils from synergy. I have a RR stubby bumper with stinger and RR rear bumper and carrier, will there be much sag? Looking to only get 2-2.5" total lift for 315s.

 

Synergy coils are designed to give the advertised height with a fully equipped jeep (bumpers, spare, winch etc.)

You should also know that they do not remove the factory rake.

I run their 3" coils on my JKU and love them.

 

You could check out our 2.5" triple rate 2 door coils as well!

Rake can be fixed w 3 rear and 4.5. Synergy is a smooth ride

 

I run those coils in the 4" on my two door and believe me, youll definitely get the advertised lift! I've got steel on steel on steel and I'm actually above the advertised height. I love this spring and I had my buddy run the same spring and he loves it too. I've had mine on almost a year and mine actually did correct my factory rake but not on my friends 4 door

 

Just to add that Synergy coils have higher spring rate than the stock (as mentioned above - they are intended for equipped rigs). So if your rig is "stock", you will get more than advertised lift out of them and more importantly, your ride will be quite harsh. And yes, they are intended to keep the rake, but can be mismatched (F/R) in order to get rid of it.

 

My wife's Jeep has the Synergy 2/3" coils on it. It is a 2 door and far from light, but we still got 4" of lift. In our case, they DID remove the factory rake. I am pretty sure that Synergy does not have a progressive rear coil for this lift amount. (I know we have a progressive in the front and mono-rate in the rear.) They are better paired with a softer valved shock over firm. We currently have Bilstein 5100s and I do not like this pair. I will be switching soon to OME or Rancho. The rear springs are shorter than others on the market and you may have to retain them if running long rear shocks and setting up for big droop.
