Benefits of the 10HTSP350

The QA1 10HTSP350 is crafted from high-tensile chrome silicon alloy, which allows for a lighter design without sacrificing strength. With fewer coils and a smaller wire diameter, these springs provide increased travel and reduced unsprung weight, resulting in quicker reactions and optimized suspension performance.

Thanks to the advanced manufacturing processes, including cold winding, heat treating, and shot peening, these springs are built for durability. The squared ends ensure straight and consistent operation, while the clear markings for free length and spring rate make identification a breeze.
