PowerStroke shocks come pre-filled with 200CST oil and medium springs installed, so you can mount them straight out of the package. Designed as a true bolt-on upgrade, they instantly improve damping consistency, reduce bounce, and increase high-speed stability, making them the perfect first upgrade for any Micro-B/T.
Built from CNC-machined aluminum with copper anodized shock bodies and black anodized caps, PowerStroke shocks offer superior strength over stock plastic units. The rigid construction enhances damping precision, improves durability, and maintains consistent performance under racing conditions.
The emulsion-style oil-filled design includes a bleeder screw and robust copper washer gasket system to ensure proper sealing and consistent rebound. This setup allows drivers to fine-tune suspension feel for different surfaces and driving styles, delivering predictable control lap after lap.
Dial in ride height and spring preload with adjustable threaded collars for fast trackside tuning. Whether you're fine-tuning for grip, stability, or jump landings, these shocks provide real suspension adjustability that stock units simply cannot match.
Designed with racers in mind, PowerStroke shocks are fully rebuildable using PRO643410 components. They are also cross-compatible with LOS-1991 springs, expanding tuning options and ensuring your Micro-B/T suspension evolves with your driving style and competition needs.
