4X Threaded Hinge Pin 4x56mm for X-MAXX 8S 77086-4 XRT 8S 78086-4 Upgrade Parts

Description

Product Overview

The 4X Threaded Hinge Pin 4x56mm from YoyoHobby is engineered specifically for the X-MAXX 8S (part number 77086-4) and XRT 8S (part number 78086-4) radio‑controlled models. Constructed from high‑grade, heat‑treated steel, the pin offers exceptional strength and resistance to wear, ensuring that the hinge mechanism operates smoothly even after countless high‑speed maneuvers. The pin measures 4mm in diameter with a 56mm length, providing a precise fit that matches the original OEM specifications while delivering enhanced durability. Its threaded design allows for easy installation and secure fastening, reducing the risk of loosening under vibration. The product dimensions are compact, with a package size of 2.72 x 1.77 x 0.35 inches and a lightweight of just 0.634 ounces, making it simple to store and handle. This upgrade part replaces the older 4x47mm and 3x8mm pins, delivering a more robust solution for demanding RC enthusiasts.

Usage

Designed for hobbyists and competitive racers alike, this hinge pin is ideal for a wide range of RC applications, including off‑road buggies, on‑road touring cars, and drift machines. Whether you are navigating tight corners, tackling jumps, or performing high‑speed sprints, the pin’s reinforced steel construction maintains consistent hinge performance, preventing wobble and ensuring precise steering response. It is particularly beneficial for users who frequently replace or upgrade suspension components, as the threaded design integrates seamlessly with existing chassis mounts. The pin is also suitable for custom builds where reliability and strength are paramount, offering a straightforward swap that does not require additional tools beyond a standard hex driver. Its compatibility with both X-MAXX and XRT platforms makes it a versatile choice for anyone looking to standardize parts across multiple models.

FAQ

Is this hinge pin compatible with other RC models besides X-MAXX 8S and XRT 8S?

The pin is specifically sized for the X-MAXX 8S (77086-4) and XRT 8S (78086-4) chassis. While it may fit other models with similar dimensions, we recommend confirming the thread size and length before installation to ensure optimal performance.

Do I need any special tools to install the hinge pin?

No special tools are required. A standard hex driver or small Allen wrench is sufficient to thread the pin into the existing mounting holes. The design includes a smooth start thread that reduces the chance of cross‑threading.

How does the steel material improve performance compared to the original pin?

The heat‑treated steel used in this pin offers higher tensile strength and better wear resistance than many standard alloy pins. This results in reduced flex, more consistent steering response, and a longer service life, especially under high‑impact or high‑torque conditions.

What is the return policy if the pin does not fit my vehicle?

We provide a 30‑day return window for unused items. If the pin does not match your vehicle specifications, contact our support team for a replacement or refund, and we will guide you through the return process.

Can I use this pin for a custom build that requires a longer hinge length?

The 56mm length is optimized for the original design specifications. For custom builds requiring a longer hinge, you may need to source a different size or modify the mounting points. We recommend consulting with a chassis engineer before making such modifications.
