Benefits of the 10HTSP400

The QA1 10HTSP400 spring is crafted from high-tensile chrome silicon alloy, which means it's lighter and provides increased travel due to the larger gaps between coils. This design significantly reduces unsprung weight, allowing for quicker reactions and improved suspension performance.

Thanks to its specialized manufacturing process, including heat treatment and shot peening, this spring boasts a remarkable fatigue life. The coil design allows it to compress to coil-bind without compromising the spring rate or free height, ensuring reliable performance under pressure.
