Key Features
- Pre-filled with 200CST Oil — The shocks arrive completely pre-filled with 200CST oil, eliminating the time-consuming process of filling and bleeding your own shocks; this means instant suspension performance with no extra preparation required before you can hit the track.
- CNC-Machined Aluminium Construction — Built from precision CNC-machined aluminium with copper anodised shock bodies and black anodised caps, these shocks offer superior strength and durability compared to stock plastic units; the rigid construction enhances damping precision, improves longevity, and maintains consistent performance under demanding racing conditions.
- Emulsion-Style Oil-Filled Design — The sophisticated emulsion design includes a bleeder screw and robust copper washer gasket system to ensure proper sealing and consistent rebound characteristics; this engineering allows drivers to fine-tune suspension feel for different surfaces and driving styles, delivering predictable control lap after lap.
- Adjustable Threaded Collars — Dial in ride height and spring preload with fast, precise threaded collar adjustments for quick 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.
- Ready-to-Mount Design — As a true bolt-on upgrade, PowerStroke shocks come with medium springs already installed and are designed to replace your stock shocks with no complex assembly required; they instantly improve damping consistency, reduce bounce, and increase high-speed stability.
- Included Spring Options — The package includes both medium springs (pre-installed) and hard springs, giving you immediate tuning flexibility to match your driving style, track conditions, and preferred suspension feel without purchasing additional components.
- Fully Rebuildable — Designed with competitive racers in mind, these shocks feature a rebuildable design using PRO643410 components; this means your investment is protected long-term, as you can service and refresh your shocks as needed rather than replacing them.
- Cross-Compatible Spring Options — PowerStroke shocks are compatible with LOS-1991 springs, expanding your tuning options significantly and ensuring your Micro-B/T suspension can evolve with your driving style and changing competition needs.
Technical Performance
The PowerStroke Oil-Filled Shocks represent cutting-edge suspension engineering for the 1/24 and 1/28 scale RC market. Built from CNC-machined aluminium with precision tolerances, these shocks deliver superior damping performance compared to plastic stock components. The 200CST pre-filled oil provides consistent viscosity for predictable rebound characteristics, whilst the emulsion-style design with integrated bleeder screw ensures reliable operation across varying temperatures and driving conditions. The 5mm inner diameter represents the optimised sizing for Micro-B/T and Micro-T platforms, providing the ideal balance between shock travel and compact package design. With adjustable threaded collars on the shock caps, drivers can dial in precise ride height and preload settings without needing to disassemble components. The copper anodised shock bodies and black anodised caps aren't just cosmetic choices—they provide enhanced corrosion resistance and durability against the wear and tear of regular racing use. Whether you're running on carpet, asphalt, or outdoor dirt surfaces, these shocks maintain consistent performance. The inclusion of both medium and hard spring sets means you have immediate tuning flexibility, allowing you to optimise suspension for grip-focused racing or a more compliant setup for rough terrain. For UK RC enthusiasts running ready-to-run RC platforms like the Losi Micro-B and Micro-T, these shocks represent the most practical suspension upgrade available, offering professional-grade performance without requiring specialised tools or extensive technical knowledge.

Frequently Asked Questions
- Are PowerStroke Oil-Filled Shocks suitable for beginners? — Absolutely. These shocks are designed as a bolt-on upgrade requiring no special assembly or tools. They come pre-filled, pre-assembled with springs, and ready to mount straight out of the box. Beginners benefit immediately from improved suspension performance without needing to understand shock tuning or oil filling techniques. The adjustable threaded collars make it easy to experiment with different ride heights and feel, allowing new drivers to learn how suspension affects handling in a practical, hands-on way.
- What oil viscosity do these shocks use? — PowerStroke shocks are pre-filled with 200CST oil, a viscosity specifically chosen for optimal damping performance in 1/24 and 1/28 scale platforms. This viscosity provides the right balance between fast rebound for responsiveness and damping control for stability. The 200CST specification means the shocks are calibrated for smooth suspension action across typical racing speeds and track conditions.
- Can I use different springs with these shocks? — Yes. The package includes both medium springs (pre-installed) and hard springs for immediate tuning. Additionally, these shocks are cross-compatible with LOS-1991 springs, significantly expanding your spring options. This compatibility allows you to fine-tune suspension compliance for different driving styles, track surfaces, or weather conditions as your skills develop and your needs evolve.
- How do the adjustable threaded collars work? — The threaded collars at the top of each shock allow you to adjust ride height and spring preload without disassembling anything. Simply turn the collar to compress or release the spring, changing how much preload is applied. This enables quick trackside tuning adjustments—if you need a slightly higher ride height for more grip or a lower stance for stability, you can make these changes in seconds without tools.
- What is the difference between these and stock plastic shocks? — Stock shocks on the Micro-B/T are typically plastic with basic damping. PowerStroke shocks offer several advantages: CNC-machined aluminium construction is stronger and more durable; pre-filled 200CST oil provides consistent, predictable damping versus stock designs; the emulsion design with bleeder screw delivers smoother, more controllable rebound; adjustable threaded collars provide real tuning capability; and the overall engineering focuses on precision and performance rather than cost reduction. The result is noticeably smoother suspension action, reduced bounce, better corner traction, and more consistent lap times.
- Are these shocks rebuildable? — Yes. PowerStroke shocks feature a fully rebuildable design using PRO643410 components. This means you can service, refresh, and maintain your shocks indefinitely rather than replacing them, making this a smart long-term investment for serious racers. Rebuilding allows you to replace worn seals, refresh the oil, and maintain performance year after year.
- What makes the emulsion design better? — Emulsion-style shocks use a mixture of oil and air in carefully controlled proportions to provide consistent damping across a wide range of shaft speeds. The integrated bleeder screw and copper washer gasket system ensure this emulsion stays properly sealed and stable. This design delivers more predictable rebound control than simple oil-filled shocks, meaning your suspension behaves consistently whether you're accelerating off the line, cornering, or landing jumps, which is critical for competitive racing where consistency directly impacts lap times.
- Will these shocks fit my specific Micro-B or Micro-T model? — These shocks are confirmed compatible with Losi 1/24 Micro-B 2WD Buggy RTR (both White and Silver), and Losi 1/28 Micro-T 2WD RTR Stadium Truck (both White and Silver). If you own one of these specific models, installation is straightforward—they're designed as direct replacements for stock shocks. The 5mm inner diameter and shock geometry are optimised for these platforms.
