Overview
The Pro-Line PowerStroke 1/10 Rear Shocks represent a significant performance upgrade for short course truck enthusiasts across the UK and beyond. Whether you're piloting a stock Traxxas Slash, running an SC10, or exploring the versatility of the Ultima SC, these purpose-built shocks deliver championship-level suspension performance that transforms how your RC truck handles on track, at the local bash spot, or during competitive racing events. Pro-Line Racing, a world-class American manufacturer with 12 IFMAR World Championships and hundreds of U.S. National and European Championships to its name, has engineered these shocks to provide the kind of suspension tuning and durability that separates casual RC enthusiasts from serious competitors.
If you're looking for a single performance upgrade that will make the most noticeable difference to your short course truck's handling characteristics, suspension compliance and overall capability, the PowerStroke Rear Shocks are exactly what you need. These shocks combine professional-grade engineering with user-friendly assembly and adjustment, arriving pre-assembled so you simply need to add shock oil and you're ready to hit the ground running. The investment in quality suspension is what separates an enjoyable RC experience from a frustrating one, and Pro-Line's reputation for manufacturing the best RC parts in the USA for over 35 years means you're buying proven performance backed by real-world racing success.
Available now for the serious RC truck owner, whether you're based in the North West, South, or anywhere across the UK, these shocks pair perfectly with the matching PowerStroke Front Shocks (PRO606300) to create a complete suspension package that handles like a vehicle costing significantly more. With infinite spring pre-load adjustment, true dual-stage spring rates, and beefy 3.5mm shock shafts, you have the tuning flexibility to dial in your setup for everything from loose dirt to technical track conditions.
Key Features
- Aluminium Body and Shock Cap — The use of high-quality aluminium construction ensures that these shocks are lightweight yet incredibly rigid, reducing unwanted flex during aggressive cornering and providing consistent suspension response throughout your driving session. This material choice is critical for maintaining precise handling characteristics in short course trucks where every thousandth of a second counts.
- Beefy 3.5mm Shock Shafts — These thicker-than-standard shock shafts provide significantly greater strength and rigidity compared to smaller diameter alternatives, which means less deflection under load and more predictable suspension behaviour. The larger diameter shaft also distributes impact forces more effectively, extending the working life of your shocks during intensive use.
- True Dual-Stage Spring Rate — This innovative spring design allows the suspension to behave differently under light loads and heavy impacts, providing both comfortable ride quality during normal driving and firm support during aggressive cornering or landing jumps. The dual-stage system gives you suspension performance that adapts to real-world driving conditions automatically.
- Infinite Spring Pre-Load Adjustment — Rather than being limited to fixed pre-load settings, these shocks allow completely smooth, infinitely adjustable spring pre-load tuning, enabling you to fine-tune your ride height and suspension stiffness to match track conditions, your driving style, and your vehicle's weight distribution with precision that simply isn't possible with standard shocks.
- Free Flow Molded Pistons — The specially designed piston geometry allows shock oil to flow more efficiently through the damping channels, providing more responsive suspension action and better ride quality. This engineering detail means the suspension reacts faster to track variations and bumps, improving both handling and comfort.
- Dual O-Ring Seats and Upper and Lower Shock Shaft Guides — These precision components ensure the shock shaft moves in a perfectly straight line through the shock body, eliminating binding and maintaining consistent damping characteristics throughout the shock's full range of motion. This level of engineering precision is what distinguishes professional-grade shocks from budget alternatives.
- Bladder Sealed Shock Cap — The sealed design prevents shock oil from escaping during intense driving sessions whilst also preventing air and moisture from contaminating the oil, maintaining performance consistency and extending the working life of your shocks significantly compared to open-style designs.
- Injection Molded Spring Retainer and Shock Ends — Using injection-molded components rather than machined metal ensures precise, consistent manufacturing tolerances whilst keeping weight low and durability high. These components are engineered to withstand repeated impacts and the stresses of competitive racing without cracking or failing.
- Pre-Assembled Ready to Run — These shocks arrive completely assembled and ready for use—simply add the recommended shock oil and install them on your vehicle. This saves you considerable assembly time and ensures professional-level quality control in the manufacturing process.
- Direct Fit for Traxxas Slash Models — The shocks fit stock Slash, ProTrac Suspension Kit Slash, and Slash 4X4 directly without modification, making installation straightforward for the most popular short course truck platform available in the UK and worldwide.
- Universal Adapter Compatibility — With the optional PRO606305 Universal Adapters, these shocks can be fitted to SC10, Ultima SC, and many other short course platforms including AE SC10 4x4, HPI Blitz, Losi SCTE, Axial EXO Terra Buggy, and Yeti trucks, making them an incredibly versatile suspension upgrade that will serve you across multiple vehicles.
- Comprehensive Tuning Ecosystem — Pro-Line offers optional spring assortment kits (PRO606304 for rear, PRO606303 for front) allowing you to experiment with different spring rates to achieve the perfect setup for your specific driving conditions, and a complete rebuild kit (PRO606302) to keep your shocks performing like new for years to come.
Technical Performance
These PowerStroke shocks represent a level of engineering refinement that reflects Pro-Line's four decades of manufacturing excellence and championship-winning heritage. The 3.5mm aluminium shock shafts are significantly thicker and stronger than those found on standard shocks, providing the rigidity necessary for precision handling in competitive short course racing. The extended length of 102mm compresses down to 74.7mm, giving you a suspension range that accommodates both smooth high-speed sections and technical rocky terrain with equal capability. The dual-stage spring rate technology works in conjunction with the free-flow pistons and dual O-ring guidance system to deliver damping characteristics that feel responsive and planted, whilst the infinite pre-load adjustment capability means you can dial in your exact ride height and spring stiffness without limitation. The bladder-sealed shock cap prevents oil degradation and maintains performance consistency throughout long driving sessions. Built from premium aluminium and injection-molded high-strength polymers, every component is engineered for durability under the stresses of competitive and recreational RC driving. Whether you're running a stock Traxxas Slash on a local UK track, bashing through a quarry with an SC10, or competing seriously with an Ultima SC, these shocks provide the suspension performance platform that allows your vehicle's handling to shine through.

Frequently Asked Questions
- Are Pro-Line PowerStroke shocks suitable for beginners and casual RC drivers? — Yes, absolutely. Whilst these shocks are used by serious competitors, they're equally suited to casual weekend bashers and RC enthusiasts simply looking to improve their truck's handling and durability. The pre-assembled design means minimal technical knowledge is required for installation, and the infinite pre-load adjustment allows beginners to find their perfect setup through simple experimentation.
- What is the difference between PowerStroke shocks and standard shocks? — PowerStroke shocks feature significantly heavier-duty 3.5mm aluminium shafts compared to standard shocks, true dual-stage spring rates that adapt to different driving conditions, free-flow pistons for more responsive damping, and precision dual O-ring guidance systems that eliminate binding. These engineering refinements combine to deliver measurably better handling, responsiveness, and durability than standard shock designs.
- Do PowerStroke rear shocks work with front shocks? — Yes, Pro-Line manufactures matching PowerStroke front shocks (model PRO606300) specifically engineered to work together as a complete suspension package. Pairing front and rear PowerStroke shocks creates a fully optimised suspension system with consistent damping characteristics across all four corners of your vehicle.
- What type of shock oil should I use? — Pro-Line recommends using standard RC shock oil available from any RC retailer. The exact weight depends on your driving style and track conditions, but 30-weight and 40-weight oils are typical starting points. Heavier oils provide more damping and a stiffer feel, whilst lighter oils allow the suspension to be more responsive and compliance-oriented.
- Will these shocks fit my specific RC truck model? — These shocks fit Traxxas Slash, Slash 4X4, and ProTrac Suspension Kit Slash models directly. For SC10, Ultima SC, AE SC10 4x4, HPI Blitz, Losi SCTE, Axial EXO Terra Buggy, and Yeti trucks, you'll need the optional PRO606305 Universal Adapters. Consult the full compatibility list or contact an authorised retailer for your specific model.
- How often will I need to rebuild these shocks? — With proper maintenance, these shocks will provide reliable service for extended periods. Pro-Line offers the PRO606302 Rebuild Kit containing all necessary components to professionally rebuild both shocks when needed, which is significantly more cost-effective than replacing them.
- Can I use different spring rates in front and rear? — Yes, and many competitive drivers do exactly this to fine-tune their setup. The optional PRO606304 rear spring assortment and PRO606303 front spring assortment allow you to experiment with different combinations to achieve the perfect balance for your driving conditions and style.
