3 link, who has em? Pros and cons.

I would like to see some jks with a 3 link rear. Do you think it's good for a daily driver. I'm thinking of getting one from RK this winter. Thanks.

The rear will feel a little looser than the OEM arrangement because there are no natural binding points like the OEM has. Without the binding your suspension is free to move nice! Properly tuned coils and shocks are a big plus as well as upping the size of the rear sway bar.

We found adding the Currie rear 1" antirock sway bar to be the perfect edition since the OEM bar is only made of 1/2" wire.

Hope that helps.

LOVE my rear 3-link. Throw in some big heims and you have as much bind-free flex as your shocks and driveline can handle! Other than the heims being a little loud when they get dirty, the 3-link performs just as good on the street as the 4 link did.

I've got the RK 3 link long arm and use my JK as a daily driver. I handles great, in fact shortly after getting it installed we too a road trip from MA to VA in the Jeep and I had no issues at all. Highways, side roads, no worries at all. On the trail its been awesome as well. I love this setup.

As you can see above the 3 link flexes like crazy. So I'll comment about living with it in a daily driver. I've got over 50K on mine and the onroad handeling is outstanding. I see no downside to running this setup.

x2 mine is three linked front and rear with the 5.5" springs. Daily drive it and it rides like a sweet dream.

For the front, you just dont run the passenger side upper.

Not to highjack, but do you guys run a 3 link over a 4 do to the limited space under the JKs or does it simply preform better than the 4 link?

The JK stock control arm configuration allows for pretty limited articulation. Things get bound up. By eliminating one upper arm and replacing the axle mounts with krawler joints will provide for some good flex

So do you replace just the driver upper arm with a rock Krawler (or similar) aftermarket arm to achieve the 3link up front? Do you need the heim joint on both axle and frame mounts?

I would like to know this as well. I do have an artic truss just waiting to be installed. will this work or would I have to sell it. im going to do the rear first for sure. So my question is can I still use my RK 2.5" spring's or do I need something different all together.

My T-Rex has a 3 link rear. Mine was done by TnT Customs. Works very well both on road and off. I like it better than the 4 link: a) less binding than 4 link--I tore my last four link off my frame while on the trail, b) flexes better, c) when flexed no "crabbing". In the front I have y-arms so it is kind of like a 3 link.

I love Wheeling, it frees the mind

I've been waiting to install a rk 3 link for quite some time. Just waiting on tires now, but all the input helps.

Is there any kind of maintenance required?

3 link has less bind in the control arms than a 4 link hands down. And this is only if you are running long shocks. At only 2.5 of lift you will see no difference. 4 link is stronger and still flexes out great with the right length shocks. Tomorrow I'm going back to 4 link if it all works out. It's not like I have 14" travel shocks with a ton of droop I will still get the same amount of flex out of my suspension.

If you want a bind free 4 link with track bar just use krawler or Johnny Joints on both ends of control arms. Takes away all the bind. Also those metalcloak joints are nice too I like em.

You can remove either side and run a 3 link front. It is much easier to do a long arm 3 link using the passenger side due to the cat that is in the way on the driver side. There are some photos in my sig link.

The only real down side to the 3 link is that if you break the upper link or mount you are screwed and will likely damage lots of stuff if you end up wrapping your axle.

You sure could! But you would have to get rid of those rear adj lower arms for the RK lower adj arms that go with their adj uppers. the ones you have on now are meant to be accompanied with the stock rear upper arms. Different lengths. You would also need their DIY 3 rink rear conversion which is a truss, one upper arm and mouting bracket.

Yes you could use either side but since the driver's side axle mount is "stronger" thats the side most people leave the upper on.

Honestly on the jk I have not seen anyone use the driver side upper mount in a 3 link. On tj's yes, but all the jk's I have seen do the passenger side.

Weird because I have seen nothing but the opposite.
