QA1 12HT150B High Travel Coil Spring 12" Length 150 lb/in Rate 2.5" ID

The QA1 12HT150B is a high-performance coil spring engineered for demanding suspension applications requiring extended travel and consistent spring rates. This 12-inch length spring features a 150 lb/in spring rate, making it ideal for performance vehicles, off-road applications, and custom suspension setups where precise load control is critical.

Key Features:

• Chrome silicon alloy construction for superior strength and fatigue resistance
• 150 lb/in spring rate provides firm, progressive compression characteristics
• 2.5-inch inner diameter fits standard coilover shock bodies and suspension components
• 12-inch free length accommodates high-travel suspension systems
• Black powder coat finish protects against corrosion and environmental damage
• High travel design allows for extended compression and rebound cycles

Chrome silicon alloy offers exceptional durability compared to standard spring steel, maintaining consistent spring rates even under extreme heat and repeated compression cycles. The protective black powder coating ensures long-lasting performance in harsh conditions while providing a professional appearance. This spring is designed to work with QA1 coilover shocks and other aftermarket suspension systems accepting 2.5-inch ID springs.
