The JAZRIDER JR-DT300-RD front lower suspension arm is a practical durability upgrade for the Tamiya DT-03. Machined aluminium delivers a stronger mounting platform compared with factory plastic arms, reducing breakage during routine running.
These arms provide a firmer feel at the steering end, translating to more repeatable cornering and fewer service interruptions. The design focuses on real-world usability rather than race-only performance tweaks.
The JR-DT300-RD installs on standard DT-03 mounting points and requires only basic RC tools. Fitment is straightforward and intended for hobbyists who want a reliable, long-lasting replacement part.
