QA1 9HTSP450 High Travel Coil Spring 9in 450lb/in Chrome Silicon

The QA1 9HTSP450 is a high-performance coil spring engineered for demanding suspension applications requiring extended travel and precise spring rates. This chrome silicon spring delivers a 450 lb/in spring rate with 3.8 inches of high travel capability, making it ideal for race cars, off-road vehicles, and performance builds where suspension articulation is critical.

Key Features:

• 450 lb/in spring rate for consistent load handling
• 3.8 inches of high travel for maximum suspension articulation
• 9-inch free length provides optimal compression range
• Chrome silicon construction for superior strength and fatigue resistance
• Tapered pigtail ends for secure coil bind positioning
• 3.57-inch inner diameter for compatibility with standard shock bodies
• Silver powder coat finish protects against corrosion and wear

Chrome silicon alloy provides exceptional durability compared to standard spring steel, maintaining consistent spring rates even under extreme heat and repeated compression cycles. The tapered pigtail end design ensures the spring coils bind properly during full compression, preventing spring pop-out and maintaining proper alignment with shock absorbers.
