MIP9820

Key Features

• Heavy-duty steel construction — Manufactured from robust steel material, this wrench is built to withstand the demands of daily pit use and frequent adjustments without bending, warping or losing its precision, ensuring your tool investment lasts for many years of reliable service.
• Large shank design for superior leverage — The generous shank profile delivers excellent mechanical advantage when tightening and loosening turnbuckles, making adjustment work faster, easier and less fatiguing during long RC racing sessions or maintenance days.
• Slim profile for tight-space access — Despite its sturdy construction, the wrench features a slim profile that allows you to reach into confined areas of your RC chassis where space is extremely limited, enabling you to adjust components other tools simply cannot access.
• Laser-engraved size identification — Crystal-clear, permanent laser engraving marks the exact size directly onto the tool, ensuring you always grab the correct wrench and eliminating any confusion or mix-ups in your tool collection.
• Colour-coded size ring — A distinctive colour-coded ring makes visual identification instantaneous, allowing you to locate the right tool at a glance even in a cluttered pit box or tool bag.
• Angled tool head for ergonomic comfort — The thoughtfully designed angled head positions your hand and wrist more naturally during use compared to straight-cut designs, reducing fatigue and improving comfort during extended adjustments.
• Tiny MIP amber handle — The compact handle is specifically engineered for RC work, providing a comfortable, secure grip whilst remaining small enough to access tight areas of your chassis without obstruction.
• Hand-assembled precision construction — Every single tool is assembled by hand by skilled craftspeople, ensuring that tolerances remain within ±0.001 inch (approximately 0.03mm) of perfection, delivering the repeatability and accuracy that competitive RC car UK builders demand.
• Versatile 3.70mm compatibility — Beyond standard turnbuckle work, this wrench also accommodates hard-to-reach 3.70mm nuts commonly found on quality RC components, making it an essential multi-purpose tool for comprehensive chassis maintenance.
• Brand compatibility — Designed with compatibility in mind for leading suspension and component manufacturers including Lunsford, JConcepts and Protek, ensuring seamless integration with the components found in high-end RC cars across the UK.
• Made 100% in the USA — Manufactured and packaged entirely in the United States, this tool represents genuine American engineering excellence and craftsmanship, supporting quality standards that are consistently recognised as superior throughout the RC industry worldwide.

Technical Performance

The MIP 3.70mm Turnbuckle Wrench Gen 2 represents the pinnacle of RC tool engineering, combining meticulous material selection with precision manufacturing processes that have been refined over more than two decades. The steel construction provides the strength necessary to handle the torque requirements of modern RC suspension systems, whilst the angled tool head design optimises ergonomics and reduces strain during use. With tolerances engineered to within ±0.001 inch (approximately 0.03mm), this wrench delivers the consistency and repeatability that competition-level RC builders require for precise chassis tuning. The large shank design provides significant mechanical advantage, making it possible to make fine adjustments with controlled force rather than excessive pressure. The slim profile is not achieved by reducing material thickness or strength; rather, it represents intelligent engineering that maintains structural integrity whilst minimising bulk. This tool is equally at home in the hands of World Champions preparing vehicles for international competition as it is with hobbyists performing routine maintenance on their RC cars. The combination of hand assembly, quality control and American manufacturing ensures that every unit meets the exacting standards that have earned MIP tools their reputation as the number-one choice in the RC industry.
