TAMIYA Hornet EVO Rear Lower Arms, Aluminum - JR-THNE02-LB by Jazrider  [JR-THNE02-LB]

Aluminum Rear Lower Arms — Hornet EVO Fit

This RC-scale rear lower arm set is a direct-fit replacement intended for the TAMIYA Hornet EVO (58742) chassis, supplied by Jazrider as model JR-THNE02-LB. Machined from aluminum, the component focuses on maintaining alignment and adding a stiffer pivot point compared with standard plastic parts, while retaining the original mounting locations for straightforward swap-in.

Installation is straightforward for hobbyists who are familiar with routine rear-suspension work: remove the original rear lower arms, retain the factory hinge pins and fasteners where applicable, fit the aluminum arms into the stock mounting points, and verify suspension travel and toe settings after reassembly. No special adapters are required when used on the Hornet EVO (58742).

When you adjust setup, the rear lower arm affects roll center, rear traction response, and the balance between understeer and oversteer. As a stiffer alloy component compared with moulded arms, these aluminium arms are typically used where consistent geometry under load helps with repeatable handling during track sessions. Confirm ride height and alignment after installation, and test with incremental changes to shock tuning and toe for best results.
