📌 Product Overview
Reliable Tension. Superior Rust Protection.
In air brake systems and mechanical linkages, a weak spring means a dragging brake or a loose lever.1 Victory Technology’s Heavy-Duty Tension Springs are engineered to provide consistent, high-force return action for truck brake adjusters, slack adjusters, and industrial machinery.
Available in three standard lengths (15cm, 17cm, 20cm), these extension springs are coiled from High-Tensile Spring Steel to resist stretching and fatigue over thousands of cycles. Finished with a durable Zinc Plating, they are built to survive the harsh under-chassis environment, resisting corrosion from road salt, moisture, and mud.
🔹 Why Choose Victory Tension Springs?
- ✅ Three Essential Sizes:We stock the most common sizes for fleet maintenance:
-
15 cm: For compact mechanisms and small brake linkages.
-
17 cm: The standard size for many truck brake adjuster returns.
-
20 cm: For heavy-duty linkages requiring extended reach.
-
- ✅ Zinc-Plated Corrosion Resistance:Springs that rust break. Our springs are fully Zinc Plated (Galvanized) to provide a protective barrier against oxidation. This significantly extends service life compared to untreated black oxide springs.
- ✅ High-Fatigue Spring Steel:Built to snap back. We use premium high-carbon spring steel that maintains its elasticity and pulling force even after constant stretching and vibration.
- ✅ Secure Open Hooks:Designed for easy installation. The robust hook ends provide a secure attachment point to brake shoes, levers, or frame rails, ensuring they won’t slip off under load.
