About this part

Shocks Overview:

Take your Arrma Grom to the next level with Pro-Line PowerStroke Aluminum Emulsion Shocks — engineered for stronger performance, smoother damping, and fully tunable suspension that dominates any terrain.

About the PowerStroke shocks


Superior Strength & Durability

Pro-Line PowerStroke shocks feature a 3mm shock shaft, thicker and stronger than the stock 2.5mm design, providing exceptional durability and confidence on demanding terrain. Precision-machined aluminum bodies and caps ensure long-term reliability, while the emulsion-style oil-filled design with bleeder screw delivers smooth, consistent damping for improved handling and reduced bounce.

Fully Tunable Suspension

These shocks offer complete tuning flexibility with adjustable shock oil, threaded composite spring collars, and interchangeable soft and hard springs. Drivers can easily set ride height, spring preload, and rebound characteristics to match any terrain or driving style. Fully serviceable and pre-filled with oil, PowerStroke shocks are ready to install and built to maintain peak performance run after run.

  • Thicker 3mm shock shaft for added strength

Douglas Cliffordon Pro-Line Arrma Grom PowerStroke Aluminum Emulsion Oil-Filled Shocks (4)

Way over rated. Unless you have to have a bleeder valve stick to the Arrma brand aluminum shocks and use high quality silicone like Flashpoint, Associated, or Losi. I'm very disappointed with these shocks. Save your money or buy from Hot Racing and take your chances there. The top "C" clip broke inside of 2 out of 4 shocks. Obviously causing catastrophic damage internally. Permanently ruined because the walls internally are now scarred beyond service with this size of piston.

Love these things. I just wish they made a progressive spring set for it.
