Jazrider Tamiya Hornet EVO Aluminum Rear Lower Arms Upgrade JR-THNE02-GU - RC Spare Part  [JR-THNE02-GU]

Hornet EVO: Aluminum Rear Lower Arms

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

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

As a hop-up these arms alter 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 at static ride height, confirming suspension travel at full droop, and re-tightening wheel hexes and hinge-pin retainers after a short test run.

Workshop notes: 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.
