QA1 12HT300B High Travel Coil Spring 12" Length 300 lb/in Rate 2.5" ID

The QA1 12HT300B 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 300 lb/in spring rate, making it ideal for performance vehicles, off-road applications, and custom suspension builds.

Key Features:

• Chrome silicon (Cr-Si) construction for superior strength and fatigue resistance
• 300 lb/in spring rate provides firm, predictable suspension performance
• 2.5-inch inner diameter fits standard coilover systems and shock bodies
• 12-inch free length accommodates high-travel suspension setups
• Black powder coat finish resists corrosion and provides a clean, professional appearance
• High-travel design maintains consistent rate through extended compression cycles

QA1's chrome silicon spring material offers exceptional durability compared to standard spring steel, resisting set and maintaining consistent performance even under extreme conditions. The precision wound coils ensure uniform rate characteristics throughout the spring's range of motion, critical for predictable handling and ride quality.
