4-40 x 5/8 E/Z Adjust Ball Link for 4-40 Rods (short) With H

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.

Each assembly includes:

• 4-40 x 5/8″ socket head bolt

• Nut

• Shim

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.
