The DU-BRO Heavy Duty Clevis w/ 4-40 Ball Link is designed for RC pilots who want smooth, precise, and reliable control movement in large and powerful aircraft. These clevises are built to deliver "no-slop" performance, making them an excellent choice for demanding control surfaces such as large rudders, elevators, or ailerons.

These clevises are a direct replacement or upgrade for the DU-BRO #3355 and #3365 Heavy Duty Clevis Horn Systems, but they can also be used in your own custom linkage setup. Each clevis includes a 4-40 heavy-duty swivel ball link, which allows the control rod to pivot freely without binding. This free-moving design helps improve control accuracy and reduces stress on your servos--especially important in large-scale or high-performance RC aircraft.

The ball links provide a solid, low-friction connection that stays tight and smooth even through vibration, sharp maneuvers, and high loads. Whether you fly scale airplanes, aerobatic models, sport planes, or giant-scale aircraft, these clevises help ensure clean, predictable control response.

Each package includes 2 clevis assemblies, and they are available in two thread sizes:

#3365 (8-32) - 4 grams each

#3366 (10-32) - 4 grams each

Both versions are extremely strong yet lightweight, making them well-suited for large aircraft that demand durable hardware without unnecessary weight.

Proudly Made in the USA, the DU-BRO Heavy Duty Clevis w/ 4-40 Ball Link provides long-lasting quality, smooth operation, and the dependable performance RC pilots trust.
