    I'm still working on picking up parts for my mini buggy that I'll eventually start building it. I'm going to make something with a similar foot print as the Fl350 and Fl400. Front suspension I'm still deciding on double A-arm and J-arm for the front, but I have fully decided with trailing arms in the back and using u-joints and not CV joint (keep costs down and keep the foot print relatively small).

    If I do J-arms I'll be using Johnny joints, however I'm not sure if I should use Johnny joints or heim joints for the trailing arms or A-arms. I've seen great success with both, but I'm not sure on the durability and longevity of heim joints if you end up jumping a bit, end up in a nasty rut, or hit a rock/stump badly. I haven't seen much as far as what people recommend and where.

    Johnny joints hold up very well. The downside to them is that they don't get as much angular movement as a hiem with a good set of misalignment's.

    Depending on how you have them mounted, this may not be an issue.

    Is there a recommended size of heim joints to use that are also commonly found?

    I ask because some of the areas I'll be riding might be more rough on suspension parts than regularly ran trails. I'll be riding in an old logging area for a long abandoned paper mill that we use for hunting.

    The hiem joints you will run will probably be overkill for the loads they are going to see. The big killer is dirt getting in them. Anything you can do to seal them up will make them live much longer.

    These guys make some good stuff.

    Also, 3 piece heims like Aurora & FK last much longer than the injection molded ones like Rod end supply.

    Looking through FK's list of heim joints, I'm on a phone so maybe their table doesn't work too well, but how would one go about choosing a set? Commercial/Industrial or Heavy Duty? They really don't have much of a description of what they are made of let alone any ideas of strength.

    After going through Aruroa, I think I'll be using them. They have a more comprehensive list of heim joints.

    Be aware, not all heims are made the same dimensionally. For instance, 7/8" FK's and Aurora's do not have the same sized balls. Aurora has several lines, COM, HCOM,Ect,ect. Make sure you misalignment's will fit the ball in the heim.

    That makes sense. Long as I build the suspension around the heim joints that I get, I should be fine?

    Is there a great alternative for heim joints to accomplish the same articulation and similar strength?
