MIP9815

Overview

The MIP 4.00MM Turnbuckle Wrench Gen 2 (MIP9815) is the professional-grade tool that has earned its reputation as the number one choice in the RC industry. Whether you're setting up a TLR, Yokomo, or Traxxas RC car, this heavy-duty steel wrench delivers the precision and reliability that serious RC enthusiasts demand. For over 20 years, MIP has been manufacturing tools in the USA that are used by World Champions and hobbyists alike, and the Gen 2 turnbuckle wrench represents the next evolution of their proven design. If you're investing in quality RC car setup and maintenance tools for your UK RC hobby, this is the wrench that will serve you reliably for years to come.

The MIP9815 is specifically engineered for adjusting 4.0mm turnbuckles on competition-level RC vehicles and can also reach hard-to-access 4.0mm nuts that other tools struggle with. Every wrench is hand-assembled and manufactured 100% in the USA, ensuring consistent quality and tight tolerances that make the difference between a sloppy setup and a precisely tuned RC car. This is more than just a wrench—it's a tool that will help you take your RC car to the next level, whether you're a weekend basher or preparing for competition.

The Gen 2 design improves upon the original with an angled tool head that provides superior ergonomics during use, a large shank that gives you the leverage needed to tighten and loosen stubborn turnbuckles with ease, and a slim profile that fits into the tight spaces that are common on modern RC chassis. Combined with laser-engraved sizing and a colour-coded identification ring, the MIP 4.00MM Turnbuckle Wrench makes quick work of any turnbuckle adjustment task on your RC car.

Key Features

• Angled Tool Head — The angled design provides superior ergonomics compared to a straight-cut wrench, reducing wrist strain and fatigue during extended RC setup and maintenance sessions, making adjustments more comfortable and precise.
• Large Shank for Increased Leverage — The generous shank design gives you the mechanical advantage needed to loosen tight turnbuckles and tighten them to the exact specification required, without slipping or damaging the fastener.
• Slim Profile Design — The slim profile allows the wrench to reach into tight and hard-to-access areas on your RC chassis where other tools cannot fit, essential for modern compact RC car designs.
• Precision Steel Construction — Manufactured from quality steel with tolerances of ±0.001 inches (approximately 0.03mm), ensuring that every wrench fits perfectly on 4.0mm turnbuckles without wobbling or over-tightening.
• Laser-Engraved Sizing — Clear laser-engraved markings make it easy to identify the correct size at a glance, crucial when you're working with multiple tools during RC setup.
• Colour-Coded Size Ring — The distinctive amber colour-coded ring on the handle provides instant visual identification, making it simple to grab the right tool in your toolkit.
• Tiny MIP Amber Handle — The specially designed MIP amber handle provides a secure, comfortable grip that's easy to control during precise turnbuckle adjustments on your RC car.
• Hand-Assembled Quality — Every tool is hand-assembled by skilled craftspeople, ensuring that each wrench meets MIP's exacting standards before it reaches you.
• 100% USA Manufactured and Packaged — Designed, manufactured, and packaged entirely in the USA, giving you the assurance of consistent quality and supporting proven tool engineering.
• Hard-to-Reach 4.0mm Nut Capability — Beyond turnbuckles, this wrench is perfectly suited for accessing 4.0mm nuts in confined spaces on your RC vehicle, making it a versatile addition to any RC maintenance toolkit.
