PA-18 T3 Dual Shock

Regular price$960.00


STC Approved for Certified PA-18 Super Cubs, the T3 Dual Suspension transforms aircraft performance with its precision-engineered design, replacing conventional leaf spring tail suspension to provide superior landing, take-off, and taxi experiences. Its coil-over style tail spring assembly, equipped with dual coil springs and oil shocks, adeptly absorbs landing energy, thereby reducing fuselage stress and elevating pilot control.


The T3 Dual Suspension, precision-engineered for superior performance, replaces traditional leaf spring suspension, providing an advanced solution for improved landing, take-off, and taxi experiences. Featuring a coil-over style assembly with dual coil springs and oil shocks, it efficiently absorbs landing energy, reducing fuselage stress and enhancing pilot control. The system includes robust mounting brackets and fixture plates for stability, secured with high-quality AN hardware for reliable flight connections.

The T3's adjustability allows pilots to control pre-load and rebound settings. Pre-load is fine-tuned by adjusting the spring perch nut, while rebound damping is easily customized through the top adjustment knob. Although factory settings are pre-optimized, pilots can perform routine checks for maintenance during pre-flight inspections.

With its revolutionary design, the T3 Dual Suspension prioritizes simplicity and efficiency, delivering optimal performance without constant adjustments and redefining aircraft handling dynamics.
