TAMIYA Hornet EVO Front Lower Arms Aluminum Upgrade - JR-THNE01-GU by Jazrider  [JR-THNE01-GU]

Aluminum front lower arms for Hornet EVO — product overview

This JR-THNE01-GU upgrade fits the TAMIYA Hornet EVO (58742) as a direct aluminum replacement for the front lower arms. The gun metal finish complements anodised hop-ups and provides a firmer mounting point than the original plastic components.

The front lower arms locate the front suspension and affect steering geometry, toe stability, and load transfer during cornering. Replacing the stock arms with aluminum pieces reduces flex at those pickup points, helping geometry remain more consistent under harder driving and during setup changes.

Installation is a chassis-level hop-up, swapping the factory front lower arms at the Hornet EVO (58742) mounting points. Reuse original hardware where applicable or refer to the product listing for included parts, and check fit and free movement through full suspension travel before final tightening.

As a baseline tuning upgrade, these arms stiffen the front of the chassis. Combine them with wheel alignment checks, damper adjustments, and suitable anti-roll bar tuning to assess handling changes. Inspect aluminum parts for stress after heavy use and confirm there is no interference with steering linkages or adjacent suspension parts.
