Secraft Stainless Steel (SUS) 4-40 Turnbuckle Pushrods (2-Pack)

Heavy-duty, fully adjustable linkage designed for maximum strength and reliability.

Secraft Stainless Steel (SUS) turnbuckle pushrods are engineered for pilots who value durability and rigidity above all else. With their size and weight, giant-scale aircraft place significantly higher demands on control systems—especially in aerobatic and gas-powered applications. These stainless steel pushrods provide superior strength, wear resistance, and long-term durability where reliability is critical.

✅ Best For:

  • High-Stress Applications: Gas aircraft, giant-scale models, and large control surfaces.
  • High-Vibration Setups: Stainless steel (SUS) offers superior wear resistance.
  • Universal Compatibility: Works with Secraft, Gator-RC, Du-Bro, and standard 4-40 ball links.

⚙️ Precision Turnbuckle Design

Each pushrod features a 4-40 RH thread on one side and a 4-40 LH thread on the other. This allows for precise length adjustments by simply rotating the center section—without removing the linkage from your servo arm or control horn.

  • Material: SUS303 Stainless Steel | Pack Size: 2 per package
  • Thread Engagement: ~0.6" per side (Constant across all sizes)
  • Adjustment: Machined center hole for fast, accurate field tuning.

Choose Your Size

Secraft 4-40 stainless steel turnbuckle pushrods are available in multiple lengths to match your control linkage setup. All sizes are measured center-to-center.

1.34" (34mm) 1.50" (38mm) 2.00" (51mm) 2.50" (64mm) 3.00" (76mm) 3.50" (89mm) 4.00" (102mm)

These 4-40 stainless steel turnbuckle pushrods are ideal for gas aircraft, giant-scale models, and high-load linkage setups where strength and durability matter most.

Note on Scaling: Thread length remains constant at 0.6" per side across all sizes. Longer pushrods increase overall length through the center section—not additional thread engagement.

💡 Gator-RC Tip: Use 4-40 jam nuts on both ends after final adjustment to lock your linkage in place and prevent rotation from engine vibration.

The Secraft Advantage: Trusted by competitive pilots worldwide, these CNC-machined SUS303 components deliver the rugged strength required for the most demanding giant-scale RC setups.
