Tamiya Hornet Evo Aluminum Rear Lower Arms by JAZRIDER JR-THNE02-GU  [JR-THNE02-GU]

Aluminum Rear Lower Arms for Hornet EVO

These aluminum rear lower arms are an RC-scale replacement part intended for the Tamiya Hornet EVO (58742) chassis, supplied by JAZRIDER as model JR-THNE02-GU. They replace the factory plastic rear lower arms with a single material upgrade, providing a stiffer mounting point that hobbyists use when adjusting rear suspension response and durability.

Compatibility is limited to the Hornet EVO designation shown in the product title. Installation follows the original mounting points and hardware on the Hornet EVO rear suspension, so the arms integrate with existing pins, hinge pins, and ball ends without requiring alternate adapters. Keep the vehicle clean and inspect pivot pins and bearings during installation to ensure proper fit and free movement.

In tuning terms these arms serve as a hop-up: they change flex characteristics compared with stock plastic arms, which can influence rear traction and transient behavior. Typical setup steps after fitting include checking toe and camber under static load, confirming suspension travel at full droop, and re-tightening wheel hexes and hinge-pin retainers after a test run.

Notes for workshop use: use the same fasteners and torque settings specified by the Hornet EVO manual, avoid over-tightening which can preload bearings, and verify clearance at full suspension articulation and steering throw before track use.
