The PAC Racing Springs Pac-1358 645 Triple Rate Coil Springs are a high-performance upgrade for your vehicle's suspension system. These springs are designed specifically for vehicles that require improved handling and a more responsive ride. Each spring is a triple rate design, which means that they offer three different spring rates in a single unit. This unique design allows for better control of the vehicle during cornering and improves overall stability.
The Pac-1358 645 Triple Rate Coil Springs are made from high-quality chrome silicon steel wire, which provides superior strength and durability. Each spring undergoes a shot peening process to increase its fatigue life and improve its resistance to fractures. Additionally, they are cold wound, which ensures consistency in the spring rate throughout the length of the spring.
The triple rate design of these springs allows for progressive spring rates. The first rate provides initial compression, the second rate handles mid-stroke compression, and the third rate manages the final stroke compression. This progressive design helps to maintain a consistent ride height and improves the handling of the vehicle during aggressive driving conditions.
Installation of the Pac-1358 645 Triple Rate Coil Springs is relatively straightforward. They come with compatible sway bar end links and bushings, and the installation instructions are clear and easy to follow. However, it is recommended that the installation is performed by a professional to ensure that the springs are installed correctly and that the vehicle remains safe for operation.
