Overview

The ARRMA Turnbuckle 5x89mm Steel Black (2) Z-AR330221 is an essential suspension component for RC enthusiasts maintaining their brushless RC trucks and buggies. These high-quality steel turnbuckles are precision-engineered replacement parts designed to keep your ARRMA RC vehicle performing at its best. Whether you're a dedicated competitor fine-tuning your 1/8 scale RC monster truck or a weekend basher maintaining your ready-to-run RC 4x4, having quality replacement turnbuckles on hand ensures you can quickly adjust suspension geometry and get back to the action. The pack includes two complete M5x89mm turnbuckles, finished in professional black to match modern ARRMA designs.

Turnbuckles are critical suspension adjusters found on modern RC cars, buggies, trucks and crawlers. They allow drivers to modify suspension ride height, camber and other geometry settings without needing to replace entire suspension arms. The ARRMA turnbuckle design is compatible with numerous popular ARRMA models including the 1/8 KRATON 6S 4X4 RTR Brushless Speed Truck, the 1/8 NOTORIOUS 6S 4X4 RTR Brushless Stunt Truck, the 1/8 OUTCAST 6S 4X4 RTR Brushless Stunt Truck, the 1/8 TALION 6S 4X4 RTR Brushless Speed Truck, the 1/7 BIG ROCK 6S 4X4 RTR Brushless Monster Truck, and the 1/7 FIRETEAM 6S 4X4 RTR Brushless Buggy. If you're running any of these models or similar ARRMA platforms, these turnbuckles should be part of your spares kit.

UK RC hobbyists know that quality spare parts are the foundation of reliable performance. Rather than settling for generic alternatives, choosing genuine ARRMA turnbuckles ensures perfect fitment and longevity. These steel components are built to withstand the rigours of competitive racing and casual bashing alike, making them an investment in your RC car's durability and adjustability.

Key Features

• Super-tough steel material — The turnbuckles are manufactured from hardened steel that resists bending and breaking even during aggressive driving or high-speed impacts, ensuring your suspension adjustments remain stable and your vehicle stays predictable in all conditions.
• Long-lasting durability and crash resistance — Unlike plastic alternatives, steel turnbuckles maintain their integrity through repeated suspension tuning cycles and the occasional crash, so you can bash harder without worrying about premature wear or failure.
• Precision manufactured threads — Every turnbuckle features precisely cut threads that allow smooth, consistent adjustment without binding or stripping, making setup changes faster and more reliable whether you're making micro-adjustments for racing or major changes for different terrain.
• Fast and easy installation — The M5x89mm dimensions are engineered for quick connection to your ARRMA suspension components, minimising downtime between runs and allowing rapid field adjustments when testing different suspension geometries.
• Specially designed adjuster — The turnbuckle body incorporates an optimised design that makes fine and precise set-up changes straightforward, enabling drivers to dial in the perfect suspension geometry for their specific driving style and track conditions.
• Black finish for cool looks — Beyond aesthetics, the black powder-coated finish provides a protective layer against corrosion and UV degradation, keeping your suspension components looking fresh and performing reliably through many seasons of RC driving.
• Pack of two units — Each purchase includes two complete turnbuckles, allowing you to replace a pair on your vehicle or maintain a backup set for competition events and practice sessions.

Technical Performance

The ARRMA Turnbuckle 5x89mm Steel Black represents the engineering standard expected from ARRMA, a brand recognised throughout the RC hobby for reliability and performance. At M5x89mm dimensions, these turnbuckles are sized specifically for ARRMA's range of 1/7 and 1/8 scale 6S brushless vehicles. The steel construction provides superior rigidity compared to aluminium or plastic alternatives, which is crucial for maintaining consistent suspension geometry when you're pushing your brushless RC truck to its limits. The precision-manufactured threads ensure that adjustments made in the pits remain stable during aggressive acceleration, high-speed cornering, and impacts. Steel's inherent properties also mean these components resist the fatigue that can develop in lighter materials after hundreds of adjustment cycles. Whether you're running a 6S LiPo powered KRATON generating serious speed or a NOTORIOUS executing massive jumps, these turnbuckles will maintain your suspension settings reliably. The black finish is more than cosmetic — it's a protective coating that guards against oxidation and wear from repeated handling and environmental exposure.

Frequently Asked Questions

• Which ARRMA models do these turnbuckles fit? — The ARRMA Turnbuckle 5x89mm Steel Black (Z-AR330221) is compatible with the 1/8 KRATON 6S 4X4 RTR Brushless Speed Truck, 1/8 NOTORIOUS 6S 4X4 RTR Brushless Stunt Truck, 1/8 OUTCAST 6S 4X4 RTR Brushless Stunt Truck, 1/8 TALION 6S 4X4 RTR Brushless Speed Truck, 1/7 BIG ROCK 6S 4X4 RTR Brushless Monster Truck, and 1/7 FIRETEAM 6S 4X4 RTR Brushless Buggy. Check your specific model's documentation or contact your local RC shop to confirm compatibility.
• Why choose steel turnbuckles over aluminium? — Steel offers superior durability, resistance to bending under load, and consistency through repeated adjustment cycles. Whilst aluminium may be lighter, steel's rigidity ensures your suspension geometry remains stable during aggressive driving, which is essential for competitive performance and predictable handling.
• How do I adjust a turnbuckle? — Turnbuckles work by rotating the central body whilst holding the end fittings steady, which shortens or lengthens the assembly. This changes suspension ride height and geometry. The precision threads allow fine adjustments for dialling in your setup.
• Are these genuine ARRMA parts? — Yes, these are genuine ARRMA components manufactured to OEM specifications. Purchasing genuine parts ensures perfect fitment and compatibility with your ARRMA RC vehicle.
• How often should I replace turnbuckles? — With proper maintenance, quality steel turnbuckles like these can last for many seasons of regular use. Replace them when you notice bent bodies, stripped threads, or difficulty making adjustments. Having spare turnbuckles on hand is essential for competitive drivers and serious bashers.
• Do I need any tools to install these turnbuckles? — Basic RC maintenance tools are typically required for suspension work. Turnbuckles use standard M5 threads and ball studs, so you'll need appropriate tools to remove old components and install new ones safely.
