wo months prior to the release of these rear A-arms for the HPI Baja 5B & 5T, we released our version of the front A-arms. In that short amount of time, the durability of our Baja A-arms displayed their unbeatable nature! That kind of performance can now be matched out back with our rear A-arms for the 5B & 5T.

RPM Baja rear A-arms start with the basic geometry of the stock arms so they are direct replacement parts – no additional parts will be needed. However, we’ve made a number of modifications to the arms from there to improve performance and durability.
