Your cart is empty. RPM Front A-arms for the Associated MT8 are designed to improve durability over stock A-arms. How did they do it? First, by increasing the amount of material surrounding the inner hinge pins by 7%, then increasing the width of that thicker diameter by nearly 40%! They then increased the amount of material at the outer hinge pins by 28%! They also increased the width there too, by another 9%.
The support beams on RPM A-arms also got beefier. At their thickest, stock a-arms are roughly 1/2" (12.7mm) thick but taper down on both ends. That amounts to a loss of nearly 30% of their thickness at the outer hinge pins. Not with RPM! Their A-arms are a full 1/2" (12.7mm) over nearly their entire length! They only taper them slightly at the inner hinge pins (.45" or 11.43mm at their narrowest) to match the maximum size allowable of the inner hinge pin bosses. To compensate for that slight taper, they use four massive support beams instead of two, making RPM MT8 A-arms the toughest alternative to stock available!
All RPM A-arms are molded from their nearly indestructible blend of engineering grade nylons for performance you can trust.
