Long Arm - Short Arm - Mid Arm??

I have been reading different things on these, wanted some opinions of the people running them on a TJ. Most of what I read says a long arm is not a good setup for a daily driver, makes the handling funny? How do they work for those that have them and drive them on the road? Short arm from what I gather is basically just a better version of stock suspension, and well mid-arm I just saw on this forum and don't have a clue

I would think a long arm would ride better on the road as the control arm angle is not as steep as my 4.5 inch RE short arm.With the long arm,As you hit a bump in the road more of the bump is absorbed by flexing the suspension,less is transmitted directly to the frame.Of course the coil spring stiffness is probably the most important factor.

Where have yo been reading??? I have had on my 2001 Jeep TJ:
1. Stock for a DD for 2 years
2. 3" Teraflex short arm kit for 1.5 years as a DD and light trail rig
3. 4.5" short arm kit for 6 months as a DD and serious trail rig
4. 5.5" short arm kit for 2 years as a serious trail rig/short trip only
5. 5.5" long arm kit for a trail rig but driven to the trails(including long trips)
6. 5.5" long arm with a 10" stretch to 104" WB as a hardcore trail rig only with a few short trips to the local store
7. 5.5"(approximate) custom long arm system with 10" rear stretch and 7" front stretch to 111" WB

The current rig is not very street friendly just because of the full hydro steering and 39" sticky tires. Other than that, hands down, the long arms ride and handle much better than ANY application, even stock. If a rig is set up properly, with a quality long arm kit, it is night and day better driving.

Depending on the trail, a long arm suspension can actually work better on the street than it can on the trail. I installed an RE long arm suspension onto my last TJ and I suddently started hanging the long arms up on the rocks on the trails I do. I'm back to shorter arms now with a full Currie suspension. On easier trails or trails without big rocks to contend with, a long arm suspension can work well.

In general -

A properly setup short arm lift at 2-3" of lift height is going to give you better all around performance than a long arm of the same height.

If you want to go tall with your rig(say you are building a show rig etc. or anything with 4+ inches of lift) then the long arm is the way to go.

However; be careful when making comparisons - as properly setup lifts are generally hard to find at any height. And there are so many other components that contribute to the ride quality that they are often overlooked. A properly setup suspension, will never need to use an excuse that it's a Jeep etc. to explain it's less than adequate ride.

You should view your situation as unique, and seek a solution that fits your needs specifically.

I run a Rock Krawler 4" X-Factor long arm suspension. The ride and drive of my Jeep on road is amazing. 100 mph, recline the seat, let go of the wheel and take a nap kinda drive. Off road the flex is amazing. I am a lot more stable than friends I wheel with that run a 4" short arm. RK lifts have bent or "dog leg" lower arms to help with the hanging up that Jerry mentions. It makes a HUGE difference. If I were to lift another Jeep, it would be very hard for me to pick another product.

I agree, love my RK stuff.
