QA1 14HT150 High Travel Coilover Spring 14 Inch 150 lb/in Rate 2.5 Inch ID

The QA1 14HT150 is a high-performance coilover spring manufactured from specially designed high-tensile chrome silicon alloy spring wire, which allows it to have fewer coils and a smaller wire diameter. This advanced design reduces weight up to 28 percent and increases travel up to 20 percent, compared with conventional springs. This 2.5-inch inner diameter spring measures 14 inches in length with a 150 lb/in spring rate.

Key Features:

• Lighter weight construction reduces unsprung weight and reacts faster, optimizing suspension performance
• Fewer coils and smaller wire diameter allow for increased suspension travel due to larger distance between coils
• Careful heat-treating and post-processing allows for greatly improved fatigue life
• Coil design allows springs to be compressed to coil-bind without affecting spring rate or free height
• Silver powder coated finish and ground at both ends for straight, consistent and accurate operations
• Clearly marked with free length and spring rate for quick identification

Proudly made in the USA, all QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions. These springs are designed for those who demand reliable performance from their suspension, offering a balanced combination of maximum travel, consistent performance, and long-term durability, whether you're on the track or driving on the street.
