Overview
Replace the flexy stock plastic front arms on your Arrma 1/18 Grom with the Hot Racing CNC Aluminum Front Lower Suspension Arm Set. CNC-machined from aluminum and finished with a clean black anodized coating, this pair of front lower arms eliminates the flex and breakage common to factory ARA330809 plastic arms — a major durability and consistency upgrade for any serious Grom build.
Aluminum suspension arms hold their geometry under hard cornering and bashing impacts, delivering more predictable handling and longer service life than stock plastic. Steel pivot balls add to the rigidity, ensuring rock-solid suspension joints from the chassis to the steering knuckles.
