Overview
The PRO 1/10 Impulse Front/Rear 1.9 inch 12mm Rock Crawler Wheels represent a significant advancement in RC rock crawler wheel design. This pair of black plastic internal bead-loc wheels has been proudly manufactured in the USA by Pro-Line, a brand synonymous with quality RC components since 1982. Whether you're an experienced RC enthusiast looking to upgrade your 1/10 scale rock crawler or a newcomer discovering the world of RC cars UK, these wheels deliver exceptional scale appearance combined with practical functionality that makes assembly straightforward and hassle-free.
What sets the Impulse 1.9" wheels apart in the competitive RC crawler market is their innovative 3-piece plastic design engineered for maximum ease of use. Unlike traditional wheel systems that require extensive hardware, the Impulse wheels need only 6 screws per wheel for complete tyre mounting, dramatically reducing assembly time and frustration. The wheels are designed to work seamlessly with Pro-Line's extensive range of 1.9" crawling tyres, ensuring that you have multiple tyre options to suit different terrain conditions and driving styles. These rock crawler wheels are an excellent choice for anyone building or upgrading a 1:10 scale RC vehicle, whether you're tackling extreme terrain or enjoying casual weekend bashing.
Built from high-strength, durable DuPont Nylon, these wheels combine lightweight construction with the durability required for genuine off-road performance. The internal bead-loc ring design and moulded lug nuts deliver an authentic, scale appearance that enhances the visual appeal of your rock crawler. If you're serious about your RC hobby and want wheels that look professional whilst performing reliably, the Pro-Line Impulse 1.9" Black wheels should be at the top of your shopping list.
Key Features
- 3-Piece Plastic Wheel Design — The innovative three-part construction allows the wheel to bolt together at the back and lock securely onto Pro-Line's comprehensive range of 1.9" crawling tyres, ensuring maximum compatibility and secure tyre retention.
- Simple 6-Screw Mounting System — Each wheel requires only 6 screws for complete tyre mounting, which is significantly fewer than many alternative wheel systems, making assembly quick and straightforward for both experienced builders and beginners.
- 12mm Hex Drive — The standard 12mm hex connection ensures compatibility with the vast majority of 1:10 scale rock crawlers and RC vehicles, including popular Traxxas TRX-4 models and numerous other brands.
- Internal Bead-Loc Ring — The moulded-in internal bead-loc ring provides a scale-appearance tyre lock without requiring separate components, whilst maintaining the structural integrity needed for serious off-road use.
- Moulded Lug Nuts — Each wheel features moulded lug nuts that add authentic detail and scale realism to your RC crawler, enhancing the overall visual presentation of your vehicle.
- High-Strength DuPont Nylon Construction — The wheels are manufactured from premium DuPont Nylon, a material chosen for its exceptional strength-to-weight ratio and resistance to impacts that occur during aggressive rock crawling and obstacle navigation.
- Front and Rear Compatibility — These wheels are designed to fit both front and rear positions on compatible 1:10 scale rock crawlers, offering flexibility in your setup and reducing the need to purchase multiple wheel sets.
- Brass Brake Rotor Weight Compatibility — The rear of each wheel is designed to accept optional Pro-Line Brass Brake Rotor Weights (sold separately), allowing you to customise the appearance and performance characteristics of your crawler.
- Popular Impulse Wheel Style — The distinctive Impulse design has become recognised across the RC community as a professional-looking, scale-appropriate wheel option that complements modern rock crawler aesthetics.
- Blacked-Out Wheel Colour — The pure black finish provides a modern, aggressive appearance that works with virtually any body colour and complements both stock and custom RC crawler builds.
- Made in the USA — Manufactured in the United States by Pro-Line, these wheels benefit from rigorous quality control and the engineering expertise of a company that has been developing RC components for over 40 years.
Technical Performance
The PRO 1/10 Impulse wheels exemplify thoughtful engineering for rock crawler applications. The 1.9-inch diameter is the standard size for 1:10 scale crawlers, providing the perfect balance between scale appearance and genuine off-road capability. At this scale, wheel diameter directly affects ground clearance, approach angles, and the vehicle's ability to traverse obstacles—the 1.9-inch specification ensures excellent performance across these metrics. The 12mm hex connection is the industry standard for 1:10 crawlers, meaning these wheels will fit directly onto any compatible rock crawler equipped with standard hex hubs. The DuPont Nylon material used in construction has been specifically chosen for its durability in demanding rock crawling conditions. DuPont Nylon resists cracking and breaking when impacting rocks, logs, and other obstacles that are part of the typical rock crawler experience. The three-piece design distributes stress more effectively than single-piece wheels, extending component life under continuous use. The internal bead-loc system, whilst primarily aesthetic, provides functional tyre retention without additional mounting hardware, reducing weight and complexity. When paired with Pro-Line's range of 1.9" crawling tyres—each engineered for specific terrain types and traction characteristics—these wheels enable genuine performance customisation. The wheel offset and width specifications match Pro-Line's line of 1.9" aluminium Pro-Forge wheels, ensuring consistent fitment and appearance across multiple wheel options within your collection.
