Dubro Swivel Ball Link 4-40 RC Aircraft Part - DUB497

The Dubro 4-40 Swivel Ball Link (DUB497) is a linkage hardware component designed for use in RC aircraft control surface and pushrod setups. Dubro's swivel ball links allow the pushrod to pivot freely at the connection point, reducing binding in control linkages and helping maintain smooth, accurate servo movement. The 4-40 thread size is a standard sizing widely used across RC plane builds, making DUB497 a practical choice when setting up or replacing linkage hardware on a range of fixed-wing models.

Key Features

• 4-40 thread size suits a wide range of standard RC aircraft control linkage setups
• Swivel action at the ball end allows multi-axis movement, reducing bind in angled or offset pushrod runs
• Threaded design enables precise pushrod length adjustment for accurate control surface neutral trim
• Durable construction suitable for repeated servo cycling across rudder, elevator, and aileron linkages
