Description
This optional set of RPM Black Losi Mini-B 2.0 Heavy Duty Rear A-arms are designed to replace the stock A-arms on your Losi Mini-B 2.0. These beefier A-arm are made of premium nylon material and are less prone to damage since the shock pivot ball is captured and no longer fully exposed. Features: The inner hinge pin bosses are roughly 20% thicker than stock (and dramatically thicker than first gen Losi A-arms).
RPM has increased the overall thickness of the A-arm by roughly another 25%.
Support beams are consistent on thickness and are roughly 50% thicker than some of the thinner supports of stock Losi A-arms.
Unique shock surround protects the lower shock bottom. It�s less prone to damage since the shock pivot ball is captured and no longer fully exposed.
