HD Tempered Valve Spring
Tax included. Shipping calculated at checkout.
The HD Tempered Valve Spring is designed to fit most Chinese 110cc to 140cc engines, as well as 150cc Lifan-style motors. Engineered for durability and consistent performance, these springs are tempered to withstand high stress and maintain optimal valve operation. Before installation, ensure your existing valve springs have a height within 1-2mm of these to guarantee proper fit and function. This upgrade helps improve engine reliability and responsiveness, making it ideal for riders seeking enhanced performance and longevity.
