Black Rear A-Arms for Tenacity/Lasernut (2) (RPM81092)

RPM rear A-arms for the Losi Tenacity line, including U4 Lasernut, replace the stock arms to deliver enhanced strength and durability for racing and bash sessions.

Made from a durable nylon blend and manufactured in the USA, these rear A-arms feature a slim, aerodynamic profile with 30° leading and trailing edges to help roll over obstacles. Outer hinge-pin supports are reinforced for added strength, reducing play and helping maintain consistent camber, caster, and toe angles. They’re sold in pairs and install as a straightforward swap with stock geometry.
