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.
- Thicker 3mm shock shaft for increased strength and durability
- Emulsion-style shock with bleeder screw for precise rebound tuning
- Threaded composite spring adjusters for easy ride-height changes
- Includes soft and hard springs for terrain-specific tuning
- Precision-machined aluminum shock bodies with laser-etched Pro-Line logo
Built Stronger Than Stock
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.
Precision Oil-Filled Performance
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.
Fully Tunable Suspension Setup
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.
Premium Materials & Finish
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.
Designed to Be Serviced
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.
