The QA1 12HT450 High Travel Spring is engineered for performance enthusiasts who demand the best from their suspension systems. With a spring length of 12 inches and a spring rate of 450 rate/in, this high-quality spring enhances your vehicle's handling and responsiveness.
Key Features
- Length: 12 inches

Exceptional Quality and Design
Crafted in the USA, the QA1 12HT450 spring is built using high-tensile chrome silicon alloy spring wire. This unique material allows for a lighter spring with fewer coils, resulting in increased travel and enhanced performance. The larger distance between coils not only reduces unsprung weight but also improves the spring's reaction time, making your suspension more responsive on the road or track.
Manufacturing Excellence
QA1 employs rigorous manufacturing processes to ensure each spring meets stringent quality standards:
- Cold Wound: Each spring is cold wound for precision.
- Heat Treated: Heat treatment enhances durability and strength.
- Shot Peened: This process improves fatigue resistance, extending the life of the spring.

With squared ends ground at both ends, the QA1 12HT450 ensures straight and consistent operation. Each spring is clearly marked with its free length and spring rate for easy identification, allowing for quick adjustments and maintenance.
Lifetime Guarantee
QA1 stands behind their products with a lifetime guarantee, ensuring that your spring will remain within 2% of its original free height and rate under normal operating conditions. This commitment to quality means you can trust the 12HT450 to perform consistently over time.
