Ok thanks anyone else feel free to chime in I heard that at via about 5k for there kit

Unless you build your own they are the only ones.

Does anyone have plans to build your own long travel arms a design with demensions or a cad drawing or jig set up for fabricating them also who makes custom axles and cv,s thanks for the info

No one really, check with Neal and see who he gets axles from. Most wont make a couple axles, there is no money in small lots. Some were taking 2 axles and cutting them, then welding/sleeving them. Downside to that now is pilot axles are getting rare. Rare = expensive. you would use the cv's from the pilot as they are proprietary and nothing else fits the existing axles or the transmission/ hub assembly. They are an oddball spline count that to date I don't think anyone has found a match for. Maybe someone else will chime in, im sure I missed something.

If your a do it your self-er. You can get parts from atvr and build your own. You can also look at what Farr posted on his arms and how to build. The only issue is the axles if you go Farr set up I do not know what axle length from stock it uses. The Dave-co is documented here and as mention by others requires axle cut and weld. As far as a complete kit and install your self atvr I do believe is the only one out there. Maybe talk to cw racing as see what they recommend since your new to pilots as he builds engines and does work on them. Now matter the route is will cost some cash to do. You either buy or build arms, bump kit etc. You can not use atvr rear arms unless relocate the shocks and mounts.
The front has to have a bump kit so the tie rods do not hit the frame and mess up the steering. The shock bracket have to move as well to use there kit. You will never get your money back so be sure its a long term investment. If you order ATVR kit most every one says its too stiff mainly in the rear and changes the shock spring out or flips them. Axis sets the valving stiff. SO consider that when ordering. I do believe and may be wrong if you order atvr kit to install your self you get no instructions on where and what to do in way of placements setting etc. So unless your willing to learn or know how consider that. Plenty of trial and error doing it your self. As far as jigs for Farr some one may have bought them not sure. There are people on here that has them both farr and atvr that can help you do if they will. I would say read up and do searches on here before you start to have a game plan as you move forward. Be prepare to spend some cash no matter what. Lots of good reads. If you do find an axle source other than ATVRs sway away or mavs or even need to do a group buy lets us know. Sway away will not sell you an axle unless its through atvr. I do not know who makes the Farr ones he never said unless I missed it. The down side is if you break one and its not a standers replacement size. May be had to replace. I have not heard of anyone breaking a farr as of yet. Shocks are another range of issues in way of building a kit your self Heims ,size, spacers, caps, valving, type of shock etc. before you make an arm or shock relocate. A lot to think about and than adapt to get it working correctly. And there the area you ride and type of ridding you do. If you throw out ideas on all a lot of us can give you feed back on what worked best for us and what did not. Maybe save you some time and hassle. Some even have twins in place of stock power plant and they can shed some light on that effect.

EDIT;
I want to add do a search here on atvr long travel before you decide one way or another.

check on this forum for Farr conversions, he stopped making them but has been great about sharing his designs for those interested in DIY.
