Du-Bro E/Z Adjust Heavy Duty 4-40 Ball Link

E/Z Adjust Heavy Duty 4-40 Ball Link from Du-Bro - DUB259

The DU-BRO E/Z Adjust Ball Links are designed for RC pilots who want strong, smooth, and highly adjustable control linkage hardware. These ball links are built for durability and precise movement, making them perfect for elevators, ailerons, rudders, steering systems, and throttle linkages. If you want more control over how your linkage feels and performs, this is an excellent upgrade. What makes the E/Z Adjust Ball Links stand out is their tension adjustment screw. This screw lets you set the exact amount of pressure on the ball, allowing you to fine-tune how tight or loose the linkage feels. You can create a super-free, low-friction movement or tighten it slightly for a firmer, more controlled feel—whatever best suits your airplane or flying style.

These parts work together to provide a secure, easy-to-install setup that stays in place during flight. The socket head bolt ensures strong clamping force, while the shim helps maintain smooth rotation and proper alignment. Despite being heavy duty, each assembly weighs only 3 grams, keeping your model light while still delivering excellent strength. Ideal for sport planes, scale aircraft, giant scale models, and precision aerobatic setups, these ball links offer long-lasting performance and dependable control. They help reduce slop, minimize binding, and provide clean, predictable motion across the entire control throw. With DU-BRO’s proven quality and engineering, the E/Z Adjust Ball Links are a smart and dependable choice for any RC pilot who wants smoother, more adjustable, and more reliable control linkage hardware.
