    When you put a lift on your Jeep like a 3.5" Rubicon Express is that considered short arm?

    Any control arm that bolts up to your factory mounts is a short arm lift. A long arm kit will REQUIRE you to cut off your mounts on the frame and relocate them more toward the center of your Jeep. This will allow you to run control arms that are SIGNIFICANTLY LONGER than stock.

    If you don't have to modify the frame mounts by moving them away from the axles, then it's still a short arm lift. Even if the new arms are longer to help dial in caster, it's still a short arm lift.

    Someone here mentioned that long arms won't increase flex. But assuming you've got some pretty long shocks (maybe 14" travel or so), won't the longer arms allow you to reach the limits of your travel with less binding angle on your arms, assuming you are running a trackbar? Or are the stock jk arms not going to bind up against the mounts anyway in either case?

    Here's a couple of shots of 14" coil overs running short arms.





    We ended up having to install limiting straps to help prevent drive line bind. We still run limiting straps with our long arms for the same reason.

    Can't really see the front driver's side to see if it's all the way into the bump but I'd imagine it's pretty close. And the passenger shock looks fully extended.

    Even looks like stock arms and not aftermarket, right?

    Not necessarily! If they bolt in factory location, they could be a mid arm! Hahaha damn you rock krawler and your invention of pushing axles too far back! But they do give my rear coils an awesome shape... similar to a slinky.

    While I would love to have a long arm, the cost and time (doing it myself) was just a bit too extensive. I've seen what short arm JKs can accomplish, and it's certainly impressive, see Eddie's photo above even if you aren't running coil overs it's pretty nice.

    I may go long arm someday, but if you want to DIY, get a good short arm, EVO + Currie and call it a day. I'm running the 4" EVO Plush Coils, EVO front lowers and Currie on the other 6. Love the lift and the ride. It wanders a bit, but I mostly feel like it's because my tires grab the road grooves and go with it, though it may be some caster as well.

    Long arm vs short arm

    Ive asked around locally and searched this forum, and have found differing opinions. I have a 2017 Rubicon Unlimited, I plan on 37's, 5.13 gears and flat fenders. Initially I planned on a 4" long arm kit, likely EVO. Now I'm thinking maybe the EVO Enforcer 3" and coil overs. Im undecided, i like the taller look of the 4". Ill probably be driving about 80% on-road. I was under the impression that the long arm kit would provide a much better ride on the pavement. Does anybody have any input as to wether the extra cost of the long arm kit would be worth it for me.

    Thanks

    Long arm will provide great road handling manners since it corrects your steering geometry.

    As far as lifts go, do the enforcer kit w/o the coilovers. If the 4" is to high when it's all said and done then you could easily sell them and get the 3" springs
