The ARRMA GROM redefined what a modern mini RC can be—and now Pro-Line is taking its suspension performance to the next level. PowerStroke Oil-Filled Shocks are a direct upgrade over stock, delivering increased strength, smoother damping, and true tunability. Designed with Pro-Line’s trusted precision, these shocks allow drivers to fine-tune oil weight, spring rate, and ride height to match any terrain or driving style, from high-speed pavement runs to aggressive off-road sessions.
