Broken A-arms will be a thing of the past when you install a set of RPM front arms! Designed to be virtually indestructible as well as lighter than stock, RPM guarantees you will never break another A-arm again! RPM A-arms are molded in our tough, custom blended nylons and are available in blue or black. Combined with #70302 rear arms (or #70305 in blue), your vehicle will be able to take cartwheels and direct hits and still be able to finish the race! RPM A-arms have captured shock mounts as well for a rock solid shock mount and the best possible ride! Tech Notes: RPM recommends the use of RPM part #70181 to replace the stock lower pivot ball on your shocks to make the best use of the captured shock mount. You will need longer shock mount screws (5/8" - 3/4" long) when using RPM GT, T2 & 10T a-arms.
