RPM RPM81092 Rear A-Arms Black Losi Tenacity Lasernut Set of 2

RPM's RPM81092 Rear A-Arms are a heavy-duty upgrade for the Losi Tenacity and Lasernut platforms, molded in RPM's nearly indestructible nylon blend and manufactured in the USA. Tightened tolerances over stock create smoother, more consistent suspension movement for more reliable camber, caster, and toe angle settings. Key areas — including the outer hinge pin support diameters — are reinforced by up to 60% over stock. A slim, aerodynamic profile with 30° leading and trailing edges helps the arms transition over obstacles rather than bluntly impacting them. Stock suspension geometry is maintained for a simple bolt-on installation. Includes 2 rear A-arms with hardware. Replaces Losi stock #LOS234017.
