not to be captain dick head, but the one guy on here saying he thinks the ride quality with a short arm vs a long arm is using this kit?



im not seeing 8 long arms, sorry. Most major vendors, and wheelers, agree that you really need to be at 4" or more to see the gains in ride height, but to say you need huge lifts to get the benefit is crazy. Just look at raised track bar brackets, there is a huge difference in handling with even a small amount of lift if you raise the roll center to be back at factory ratios, why would the control arms not see the same gains? especially when the window of caster to pinion angle is so very small for optimal ride quality?

(as to why vendors make long arms for shorter lifts, well that easy. anything to make a buck! )

My JKUR, with a full set of Full Traction 4" lift, and the Full Traction CRC (which made a major difference), rides better than when it was stock, in every aspect.
That's with short arms.

If I put in coilovers, I'd probably rather sleep in the Jeep than on my mattress...

the crc seems great, I wont argue there. it was more you said you rode in the full traction long arm and short arm, and didnt notice a difference. i bet theres a good reason for that. you know, since its not a real (good) long arm kit

This is a worth noting honest reply by TeraFlex

Well... I wouldn't call Full Traction arms "not good"... they're among the better ones available.
(You have also read good feedback from a competing vendor here.)

The only difference is the arm's length. If everything on both Jeeps was correctly tuned,
and it was, the comparison was valid.

We made that comparison before I had the CRC, which influences other things anyway, and not the softness or articulation.

when it comes down to it, while it is a valid comparison for that vendor, its not a true valid comparison. take a spin in some long arm kits that are actually long arms, or at least radius arms. keeping the factory upper lengths but going long on the bottom is not a real long arm setup. the arms will obviously bind when on the same plane, so youll get the same handling as factory. not really sure why they sell it.

but agreed completely. long arm at 2.5" is a waste of cash

There are alot of things to concider given this situation! The first things are what are your needs and what is within your budget!

A good long arm setup will always ride better and perform better than a short arm system!

Long arm systems will have reduced axle steering effect as compared to a short arm system over a given range of travel (This one is huge)...

Most major manufacturer's long arm systems are different as well which yields different charecteristics! For us, we put in really high clearance into all of our arm mounting points! We favor the independent 3 link design in JK's for bind free suspension movement! We also make sure to run full length upper control arms, not combinations of long lowers and short uppers which helps minimize axle steering effects of the shorter arms, thus maximizing performance.

At the end of the day, there are alot of pluses and minuses! You really need to figure out what is best for you and the only person that can answer that is you! Or your wife if she holds the check book! LOL.

Good luck with your builds guys. If anyone would like, feel free to give us a shout! We will be more than happy to talk Jeep with you all!

And this is why I sell more RK systems than all others put together.

I run 3.5" lift with y-link long arms. Running on 43's. I can do 90mph, no bump steer, I can also drive really fast over rocks, or just plain crawl. The long arms give good geometry, even when the mount are tucked way up.

I also have jeeps with short arms. They have mounts that fix the geometry, but they do hang down. They ride nice.

Either way the springs and shocks matter a lot.

It really depends on how you plan on using your jeep. If you are going to do a lot rock crawling with big tires, then long arm. If you are looking for a good ride, you can get it from a short or long set-up.
