Whether you are looking for the best setup for your local track or bashing around your back yard, these Pro-Line PowerStroke shocks will assure you have the best performance and a great time pushing your RC model to its limits.
Available for ARRMA Senton 3S, Typhon 3S, Granite 3S, Kraton 4S, and Outcast 4S vehicles, this suspension upgrade delivers serious performance improvements. The shock technology has been engineered by Pro-Line Racing, a recognised brand in the RC hobby, to provide the ultimate in handling, durability and tunability for your ARRMA truck or buggy.
Key Features
- 14mm Big Bore Aluminium Shock Bodies — The oversized shock bodies provide increased internal volume and superior damping characteristics, allowing for more consistent performance across different terrains and track conditions. This larger diameter means better heat dissipation and more stable suspension response during aggressive driving.
- Infinite Spring Pre-load Adjustment — Rather than being limited to fixed spring rates, these shocks allow you to dial in the exact amount of pre-load your setup requires, giving you complete tuning flexibility to match your driving style, weight distribution, and track conditions without needing to purchase different springs.
- Strong Machined Aluminium Shock Caps — Precision-machined from solid aluminium, the shock caps are engineered to withstand the stresses of high-performance RC driving whilst maintaining perfect tolerances, ensuring smooth operation and preventing leaks that plague cheaper plastic alternatives.
- Beefy 3.5mm Shock Shafts — The thicker shock shafts (compared to smaller diameter alternatives) provide superior rigidity and resistance to bending under load, meaning your shocks maintain their performance characteristics even during extreme jumps, crashes and rough terrain bashing.
- True Dual-Rate Springs — These specially designed springs provide two different rates of compression, meaning the suspension feels soft and responsive during small bumps but firms up progressively as the suspension compresses further, giving you both comfort and control in one component.
- Dual O-ring Seals — The dual sealing system prevents oil from leaking out of the shock body, maintaining consistent damping performance throughout your driving sessions and extending the lifespan of your shocks by protecting internal components from dirt and moisture.
- Upper and Lower Shock Shaft Guides — These precision guides keep the shock shaft perfectly aligned during compression and extension, eliminating bind and ensuring smooth, consistent suspension action that translates directly to better handling and predictability on the track or trail.
- Injection Moulded Shock Shaft Guard and Shock Ends — The super durable plastic components protect the shock shaft from damage whilst being lightweight enough not to add unnecessary mass, and the replaceable design means you can refresh worn parts without replacing entire shocks.
- Pre-assembled Design — These shocks come fully assembled and ready to install, saving you hours of build time and ensuring perfect factory quality assembly by professionals with decades of shock-building experience.
- Includes Longer Shock Ends for 4S Vehicles — The kit thoughtfully includes extended shock ends specifically for ARRMA 4S models, ensuring perfect fitment and geometry regardless of which ARRMA vehicle you own, maximising performance across the range.
Technical Performance
The PRO 1/10 PowerStroke Rear Shocks represent a significant engineering achievement in 1/10 scale RC suspension technology. Built with precision-machined aluminium throughout, these shocks utilise the larger 14mm big bore design that allows for superior fluid dynamics and heat management compared to smaller diameter alternatives. The 3.5mm shock shaft is noticeably thicker than stock components, providing dramatic improvements in rigidity and resistance to deflection under the extreme loads generated by modern 3S and 4S brushless RC vehicles. The true dual-rate spring system is engineered to deliver progressive damping characteristics, meaning the suspension provides a supple, compliant feel over small impacts whilst offering controlled, supportive resistance over larger compressions — exactly what's needed for consistent, predictable handling whether you're attacking a technical track or launching jumps in your back garden. Built from quality materials including machined aluminium shock bodies and caps, these shocks are designed to withstand thousands of impacts without performance degradation. The dual O-ring seals ensure oil stays where it belongs, inside the shock, maintaining consistent damping characteristics throughout extended driving sessions. For 3S vehicles, the shocks arrive ready to use after simply filling with appropriate shock oil and installation. For 4S vehicles, the included longer shock ends (measuring 119.0mm collapsed vs 116.0mm for 3S models) ensure perfect suspension geometry and ride height. The pre-assembled nature means you're getting factory quality workmanship rather than relying on amateur assembly, and the injection-moulded guards and ends protect critical components whilst remaining durable enough for serious bashers.

Frequently Asked Questions
- Are these PowerStroke Shocks compatible with my ARRMA vehicle? — Yes, these rear shocks are specifically designed for ARRMA 3S and 4S vehicles. They fit the Senton 3S, Typhon 3S, Granite 3S, Big Rock 3S (3S models), and Kraton 4S and Outcast 4S (4S models). The kit includes longer shock ends specifically for 4S vehicles, ensuring perfect fitment.
- Do I need to do anything before installing these shocks? — The shocks come pre-assembled and are ready to install. For 3S vehicles, you simply need to fill them with appropriate shock oil before installation. For 4S vehicles, install the longer shock ends included in the kit before filling with oil and fitting to your truck.
- What shock oil should I use with these PowerStroke Shocks? — Pro-Line PowerStroke Shocks work with standard RC shock oils. The viscosity you choose (typically measured in weight, such as 25, 30 or 35) depends on your driving style — thicker oil provides more damping for smooth tracks and racing, whilst thinner oil provides more responsive, compliant suspension for bashing and rough terrain.
- Are these shocks pre-assembled? — Yes, these shocks arrive fully pre-assembled by Pro-Line Racing. This saves you hours of build time and ensures professional quality assembly. You simply need to add shock oil and install them on your vehicle.
- What is the difference between the 3S and 4S shock ends? — The 4S vehicles require slightly longer shocks due to their larger size. The 3S shocks measure 116.0mm extended and 80.0mm collapsed, whilst the 4S shocks measure 119.0mm extended and 83.0mm collapsed. The kit includes both sets of ends, allowing you to use these shocks on either vehicle type.
- How do the dual-rate springs work? — The dual-rate spring design provides two different compression rates. Over small bumps, the springs feel soft and responsive. As the suspension compresses further, the springs firm up progressively, providing support and control during big impacts. This gives you the best of both worlds — comfort and control.
- What makes these shocks better than stock ARRMA shocks? — Stock ARRMA shocks are basic components designed for budget-conscious buyers. The PowerStroke Shocks feature much larger 14mm bore diameter (vs smaller stock sizes), thicker 3.5mm shock shafts for better rigidity, precision-machined aluminium construction throughout, true dual-rate springs for superior handling characteristics, and infinite spring pre-load adjustment for complete tuning flexibility. These upgrades translate to noticeably better handling, durability and performance.
- Can I tune these shocks? — Absolutely. The infinite spring pre-load adjustment allows you to dial in exactly the right amount of preload for your driving style and conditions. You can also experiment with different shock oil weights to fine-tune damping characteristics. Optional front and rear spring assortments are available for even more tuning possibilities.
- How long do these shocks last? — With proper maintenance, Pro-Line PowerStroke Shocks will provide years of reliable performance. Eventually, the O-rings may wear and require replacement (the O-Ring Replacement Kit is available), or plastic components may break from crashes (the Replacement Plastics kit is available). The machined aluminium body and caps will last indefinitely if not damaged in a major crash.
- Are these suitable for both racing and bashing? — Yes, these shocks are equally at home on the track and in the back garden. The combination of performance engineering and durable construction makes them ideal for competitive racers whilst the forgiving dual-rate springs also suit aggressive bashers who enjoy launching big jumps and tackling rough terrain.
