    JKU Long Arm vs Short Arm

    I keep going back and forth over short arm vs long arm. Most of the kits out there the long arm and the short arm use the same socks. With using the same shocks you not gaining anymore articulation one vs the other. I'm looking for input from other people out here.

    Thanks,

    The long arms are there to keep the axle arc to a minimum. You will have less bind and typically a smoother ride.

    On a JKU, the arms are already pretty long allowing for good articulation so as Sir Phillip said, it just keeps the axles in more of a vertical motion rather than a radius. You will most likely not get more travel from a long arm kit and some of the limiting factors will be drive shafts and other components.

    Long arm kits we're popular on TJs because of the short arms, but the increase complexity and expense of the long arms is not really needed for the JK.

    It also depends on the law where you live... As for myself here in QC/Canada we're not allowed to modifie the frame and we cant weld on it so a long arm kit is out of the question... On short arms kit you dont have to use stock shocks and please.. dont, they are horrible even on a Rubicon like I have ... You can buy shocks with more travel and longer coils. The main diference was explained above.

    If you want to keep your same shocks and have a lift kit then you will need shock spacers.. keep your short arms imo.. long arms wont dont much with stock shocks.

    Do you have vehicle checks every so often for them to see if it passes inspection?
