Jazrider TAMIYA Hornet EVO Rear Aluminum Underguard JR-THNE03-LB - RC Spare Part  [JR-THNE03-LB]

Rear underguard overview

This is an RC-scale aluminum rear underguard made for the TAMIYA Hornet EVO 58742 chassis and sold as model JR-THNE03-LB by Jazrider. The component is finished in anodized blue and is designed to mount to the rear lower section to protect the chassis and modify rear-end rigidity.

Functionally, the underguard acts as a protective skid plate that resists abrasion from impacts and track contact while producing a measurable change in lower rear stiffness. Drivers can use this change to fine-tune handling on carpet or hardpack tracks, noting that fitment is specified for the Hornet EVO 58742 only.

Installation notes: the plate aligns with the Hornet EVO 58742 rear mounting points and retains the original screw pattern and clearances. Fitting normally replaces the stock plastic plate with the anodized aluminum unit; check clearance around the rear suspension and bumper to avoid interference with travel.

Tuning considerations: moving from plastic to aluminum shifts rear lower stiffness and contact behavior, which can improve stability on high-speed exits while increasing bump sensitivity. Treat this underguard as part of a broader setup process alongside shock and anti-roll adjustments to achieve balanced rear traction and steering response.
