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.
PowerStroke shocks feature a 3mm shock shaft—significantly thicker and stronger than the stock 2.5mm design—providing added durability and confidence when pushing your GROM harder across demanding terrain.
The oil-filled emulsion design with integrated bleeder screw allows you to set precise rebound characteristics, ensuring consistent suspension performance and improved handling across a wide range of driving conditions.
PowerStroke shocks give drivers three critical tuning options—shock oil viscosity, threaded composite ride-height adjustment, and interchangeable soft and hard springs—making it easy to dial in the perfect setup for speed runs, bashing, or off-road performance.
Precision-machined aluminum shock bodies and caps provide smooth operation and long-term durability, while the laser-etched Pro-Line logo adds a premium finishing touch worthy of a high-performance upgrade.

PowerStroke shocks are fully serviceable and supported by replacement shafts, springs, seals, and rebuild kits, ensuring your investment stays performing at its best run after run.
