Hey everyone, sorry for the delay in my response.
First off, I don't want anyone to think that I am bashing Evo at all. I am not. They are a great company and they make solid parts. Jefe was not sold because I think a JKS Jspec is better than a DTD. Trying to compare a DTD to a Jspec is apples to oranges. Two very different suspensions meant for two very different purposes. Jefe was an incredible Jeep and rode well both on and off road. My reason for selling was purely business related. I took a long, hard look at what kind of Jeep we were putting out on a regular basis. It was usually a Jeep on 35's, maybe 37's, some nice bumpers, winch, beadlocks and a Jspec. We build a lot of those Jeeps every year. I realized that I was driving a Jeep (Jefe) that we build maybe two or three of in a year. I wanted to show my customers that I wasn't just talking the talk but I am also walking the walk. I wanted my current and future customers to see that because I believe in the products I sell and install so much that I am also using them. My wife's Jeep built the same way. Yes customers would come in and be amazed by Jefe (and they should be, the DTD kills it!) but most Jeep owners can't afford a vehicle like that. Will I miss my DTD? Absolutely, I already miss it! But I am also looking forward to showing customers that what I am suggesting you use on your Jeep, also is being used on my Jeep.
Ok so the meat and potatoes on this thread. Why do I choose the Jspec. It all revolves around the coil. JKS uses a cold wound dual rate coil which provides good wheel travel, load handling, on road handling and a predictable ride height and street ride. I also liked that they provide 2 and 4 door specific coils for 2.5" and 3.5". Again not bashing the Enforcer but there were times where a 3" plush ride on a 2 door would be to much for 35's. We normally found this with lighter Jeeps (plastic bumpers for example). Back to the JKS coils. Their first stage is short and very compliant but the second stage is larger and very aggressive. This means that the Jeep rides in the first stage but the second stage takes the vehicle's weight. The key for the coils' ability to take a load, handle well and control wheel travel is because the second stage engages before the first stage is fully compressed.
We all have different opinions on coil construction and that is ok. I am not here to try and convince anyone that a dual rate coil is better than a linear coil. I felt that a dual rate coil provides my customers with the best ride possible for their Jeep and so far they have been agreeing with me.
I hope that makes sense. JKS and their engineers really took the time to educate us on their coils as they recognize that the coils are what makes their kit different. They will even be the first to say that other companies like Evo, Teraflex, MetalCloak, and AEV make good parts but in the end they all have different philosophies on how to make a Jeep ride.
If anyone has a specific question about the JKS Jspec or the Evo Enforcer please feel free to message me, call me or email me!
