Secraft 4-40 Aluminum Turnbuckle Pushrods (2-Pack)

Lightweight, fully adjustable control linkage for precision RC aircraft.

Secraft 4-40 aluminum turnbuckle pushrods are designed for modelers who demand precise control geometry without the hassle of removing linkages for adjustment. The dual-thread design allows for high-precision fine-tuning simply by rotating the center section. These offer the ultimate in strength and security for giant-scale and F3A aircraft where control systems face the highest demands.

✅ Best For:

  • Giant-Scale & F3A: Handles high-load surfaces with critical weight savings.
  • High-Performance: Engineered to help eliminate slop in control linkages.
  • Compatibility: Ideal for Secraft, Gator-RC, or Du-Bro 4-40 ball link systems.

⚙️ Precision Turnbuckle Design

Featuring a 4-40 RH thread on one end and a 4-40 LH thread on the other, these allow for precise length adjustments without disconnecting your linkage from the servo or horn.

  • Material: CNC-machined aluminum | Pack Size: 2 per package
  • Engagement: 0.6" thread depth per side for maximum security.
  • Easy Tuning: Machined center hole for adjustment with a small tool.

📏 Available Lengths (#4-40)
