TAMIYA Hornet EVO Rear Undertray Aluminum JR-THNE03-LB by Jazrider  [JR-THNE03-LB]

Rear chassis protection and stiffness

This aluminum rear underguard was made for the TAMIYA Hornet EVO 58742 chassis and is offered as JR-THNE03-LB by Jazrider. The anodized blue plate mounts to the rear lower area to protect the chassis underside and alter the lower rear stiffness profile.

The plate functions as a durable skid element that resists abrasion from track contact and minor impacts, while delivering a measurable change in rear lower stiffness that can be used during setup work. The listing is specific to the Hornet EVO 58742 chassis and does not imply compatibility with other models.

Installation guidance: the underguard aligns with the Hornet EVO 58742 factory mounting points, preserving original screw locations and clearances. Typically you replace the stock plastic unit with the aluminum component and then check that the rear suspension and bumper clearances are maintained throughout travel.

Tuning advice: moving from plastic to an aluminum skid plate increases lower rear stiffness which can stabilise corner exits but could amplify bump feedback. Include this change in a wider setup process that involves shock damping and anti-roll adjustments to regain balance.
