Rock Krawler 3.5 Max Travel, (bushings worn out?)
The gal has a '12 JKU with what I think is a RK 3.5 max travel (if I remember right). It was installed a couple years ago. It's a stick shift and she has a lead foot along with the jackrabbit starts. I drove it the other day and the back end shifts (kind of, side to side) when I'm on and off the gas. I believe some bushings may be worn, and have not bothered to climb under and have a look as of yet (winter you know).
Does RK sell a bushing kit for periodic maintenance for their kits?
Or am I on my own to gather the worn parts that will be needed?
Any of you dealt with this issue recently?

I had one of my front RK bushing wear out only about 1300 miles of installing the kit. I called rock krawler and sent them pics and they sent me a new one. I have been running the new one for about another 1200 miles and its starting to come apart.

Guys
We apologize for any issue that may have happened and were backed up by the manufacturer 100% so anyone that had an issue would be taken care of 100%.
As far as any bushing wearing prematurely at this point, it has been a very rare occurrence if any. Here is our bushing warranty and we stand behind it.. Even for guys with service parts. We do like to see images of them installed in the vehicle so we can try to provide the best possible tech support as well.
There are many variables that can cause control arm bushing premature wear. Not just ours. Here are a few that some people miss.
Exhaust rerouting too close to bushings causing them to heat cycle or get too hot so they deform. On JK 2012 and up this is typically found on the DS front lower arm when exhaust spacers or something to that effect is used. The front upper arm joint at the frame has exhaust shielding on it so it is protected, but when the exhaust is moved down, very rarely do people add the shielding to the lower arm which is now susceptible to the same heat issue. The other is, the axle end joint can be misaligned causing excess stress on the control arm bushing on the frame.
Either way, we are here to help. Just give us a shout.

Well, turns out a new off-road shop opened in the area. Guy seems pretty knowledgeable, and I work two gigs and take care of property too. So we will be getting a quote and a list of what is needed. I don't mind helping a local new business if it means saving me some grief...
Just to make this clear. I have no complaints on the RK product, it rides and handles great. I really think the root cause is ... I can't say because she might read this (ha). In fact I am looking to purchase a 2.5 x factor for my 2 door shortly after Christmas.

After a couple of years on/off road, including winter road salt, I had my rear lca bushings wear out. I sent RK a short video of the arm movement at the bushing ends, followed up with a phone call and they sent me new ones without issue. It's a benign process to replace them but with the new ones, I packed them full of synthetic grease before installing this time.
