Pro-Line Racing PowerStroke Oil-Filled Rear Shocks: ARRMA MINI KRATON PRO643301

Built Stronger Than Stock

PowerStroke Shocks upgrade the stock 2.5mm shafts to a robust 3mm design, increasing durability and resistance to bending under aggressive driving, jumps, and high-speed landings.

Precision Oil Damping

The oil-filled emulsion design paired with an integrated bleeder screw ensures accurate oil volume and consistent rebound, giving you predictable handling across changing terrain.

Tune for Any Terrain

PowerStroke Shocks allow tuning through shock oil viscosity, threaded aluminum spring adjusters for ride height, and included soft and hard springs-letting you fine-tune suspension feel for speed runs or off-road performance.

Premium Pro-Line Construction

Machined aluminum shock bodies and caps deliver strength and smooth operation, while the laser-etched Pro-Line logo adds a premium finish you can trust.

Fully Serviceable Design

Designed for long-term performance, PowerStroke Shocks are fully rebuildable with available rebuild kits and replacement front or rear shock shafts sold separately.
