Built by RC4WD, a recognised leader in scale RC technology and crawler engineering, the Plastic Punisher Shaft V2 represents the latest evolution in injection-moulded driveshaft design. This component combines advanced internal spline geometry with carefully selected materials to deliver superior performance whether you're navigating rocky obstacles, testing suspension flex on a trail course, or pushing your ready to run RC crawler to its limits. The V2 designation indicates this is an improved design over the original, incorporating lessons learned from real-world use and feedback from the RC community across the UK and beyond.

The lightweight plastic construction keeps rotational mass to a minimum, which translates to quicker response times, improved efficiency, and reduced strain on your motor and gearbox. Yet RC4WD hasn't compromised on strength—strategic use of steel components where they matter most ensures this shaft can handle the torque and abuse that serious crawling demands. With a 5mm bore hole and compact outer diameter of 12.9mm, this shaft integrates seamlessly into existing RC4WD drivetrain setups, making it an ideal replacement part or upgrade component for your crawling platform.

Key Features

• Advanced Internal Spline Design — The sophisticated internal spline geometry ensures smooth, reliable articulation even during extreme suspension travel and sharp steering inputs, preventing bind-up and maintaining consistent power delivery across your RC crawler's full range of motion.
• CNC Machined Components — Critical steel elements are CNC machined to precise tolerances, ensuring perfect compatibility with your RC4WD transmission and suspension components whilst maintaining tight fits that eliminate wobble and flex.
• Mixed Material Construction — Strategic combination of ABS plastic and steel materials provides optimal balance between weight savings and durability, with steel reinforcement exactly where it's needed most to handle the stresses of serious crawling.
• 5mm Bore Hole — The 5.1mm hole size (0.20 inches) is specifically designed for RC4WD's transmission and universal joint configurations, ensuring perfect fit and eliminating the need for grinding or modification.
• Compact Outer Diameter — At just 12.9mm (0.50 inches) in outer diameter, this shaft maintains a low profile within your chassis whilst delivering maximum articulation, crucial for fitting within tight suspension geometry on scale crawler builds.
• Lightweight Design — Weighing only 29.5 grams (1.04 ounces) each, the plastic Punisher Shaft V2 minimises unsprung weight, improving suspension responsiveness and reducing the overall load on your RC crawler's drivetrain components.
• Custom Length Capability — The plastic construction allows you to trim the shaft to custom lengths, enabling perfect fitment for specialised builds or modified wheelbase configurations on your trail crawler.
• Stackable Configuration — Can be combined with part numbers Z-S2019 and Z-S2021 to create different overall lengths, giving you maximum flexibility in designing your perfect crawler setup.

Technical Performance

The RC4WD Plastic Punisher Shaft V2 Z-S2020 is engineered to deliver smooth, predictable power transmission across the full range of suspension articulation that modern RC crawlers demand. The advanced internal spline prevents mechanical bind-up, which is critical when your ready to run RC vehicle is navigating rocky terrain or executing extreme flex manoeuvres where suspension components move through their complete range of travel. The 15.0mm (0.59 inches) travel distance specification indicates this shaft accommodates significant U-joint angle changes without introducing vibrational harshness or noise into your drivetrain. The combination of injection-moulded ABS plastic with strategically placed steel components creates a shaft that's both responsive and durable—the plastic absorbs minor vibrations and impacts whilst the steel maintains structural integrity under sustained torque loads. The 5mm bore hole and 12.9mm outer diameter integrate perfectly with RC4WD's transmission designs, which have been refined through years of scale crawler development. This shaft maintains dimensional consistency across its 102-110mm length range, and because the plastic can be trimmed by the user, it offers unprecedented adaptability for different suspension setups, wheelbase configurations, and driveline angles. Whether you're running a short-wheelbase crawler configuration or a longer modified chassis, this shaft delivers the responsive articulation and reliable power delivery that separates a premium RC crawler from basic hobby-grade vehicles.
