The JR-THNE02-BK rear lower arm is an aftermarket aluminum replacement crafted for the TAMIYA Hornet EVO (58742). Finished in black anodize and machined for consistent geometry, the arm replaces the standard plastic units to provide a firmer mounting location for rear suspension components.
Designed to keep the original pivot and mounting positions, the part integrates with existing hubs, links, and shock mounts without chassis modification. This makes it a straightforward upgrade for users seeking reduced flex and more repeatable handling characteristics.
Installation is direct: remove the rear hub carriers and fasteners, swap in the aluminum arms, and secure with the factory hardware following recommended torque values. After fitting, check alignment and pivot-bushing clearance to ensure controlled movement.
