Overview
The RPM Front A-Arms for the 4S V2 Arrma Kraton and Outcast are designed primarily for strength and durability, with several extra features built in. These front A-arms eliminate slop by reducing the amount of movement at the hinge pins, providing better steering response and more consistent camber, caster, and toe angle settings.
RPM's improvement includes the addition of a second shock mount hole further out on the arm, providing a lower-profile suspension setup. This shock position allows the suspension to lay down further, dropping the ride height for a lower center of gravity and better cornering stability. The A-arms are massive and uniform in thickness across their entire length, molded from RPM's ultra-tough engineering-grade nylons.
