ATV A-Arms

ATVs sport a fairly unique suspension setup since they use a-arms (known as control arms in some circles). The a-arms are what help the vehicle traverse all types of terrain when out on a trail. But that also leads them to be exposed to rocks or other hazards. If you find yourself in need of some new a-arms, don’t fret. Rocky Mountain ATV/MC is on your side; we’ve got you covered.

We carry the prestigious Armadillo chromoly a-arms in stock for many types of ATVs. Some of them are even the extended +2 inch style. Armadillo is known as being an industry leader for ATV a-arms; that is why we’ve chosen to carry their product. And if you need to replace the ball joint or bushings on an existing Armadillo a-arm, we’ve got replacement parts to make your life easier.

If you’re just in the market for extra protection for your existing ATV a-arms, we’ve got several options of guards. Depending on the availability for your particular machine, we stock the following brands:

  • Ricochet
  • Armadillo
  • Pro Armor
  • Tusk

All of these are fine choices and will help protect your a-arms from receiving unnecessary damage. Go ahead and enter your quad’s details in the drop-down boxes above to see what a-arm products we have available for you.

    Great product and great price!

    These seem like a quality product. They went on fairly easily. I had to trim the factory skid plate a bit but the instructions said I would. I think these will save me money in the long run! Dave

    Billy in UT

    Had to open up the holes to get to it to fit.

    I had to use a die grinder and a burr to oval the holes to get the bolt holes to line up.

    Only have one gripe with these there is always one clamp that dose not quite fit right but once you get over that hides they are good looking protect your a-arms could be a little taller by the cv-boots to protect them more but over all as advertised

  • Tusk Ball Joint Tool

    Tusk Ball Joint Tool

    Paul in NV

    Works ok but...

    Used this on the SuperATV Forward A-Arms. Works well for removal of the old ball joints. Does not work well with the ball joint install on the bottom A-Arms. It’ll do the job but you have to keep repositioning the tool.
