What does the spring rate (650 lb/in) mean for my vehicle?

A spring rate of 650 pounds per inch means that it takes 650 pounds of force to compress the spring by one inch. A higher spring rate generally results in a firmer ride and less body roll during cornering, offering improved handling response.

What is the inner diameter (ID) of this spring?

The inner diameter of this Ridetech coil spring is 2.5 inches. This is a common size for many coilover shock bodies and suspension setups, but it's always best to measure your existing components to ensure a proper fit.

What is the free length of this spring?

The free length of this coil spring is 10 inches. This measurement is taken when the spring is not under any load or compression. It's an important dimension for determining suspension travel and ride height.

Product Details

This is a Ridetech coil spring, measuring 10 inches in free length with a spring rate of 650 pounds per inch. It features a 2.5-inch inner diameter, making it suitable for a wide range of suspension applications. These springs are often used when rebuilding or upgrading suspension systems, particularly for coilovers where precise spring rates are crucial for handling and ride quality.

The 650 lb/in rate offers a firmer spring than stock, which can help reduce body roll during cornering and improve the responsiveness of your vehicle's suspension. The 10-inch length and 2.5-inch ID are common dimensions that allow for compatibility with many aftermarket shock bodies and suspension setups. Ridetech is known for well-built suspension components, and these springs are designed to provide consistent performance.

When installing these springs, especially in a coilover assembly, ensure you have the correct spring compressors and follow the manufacturer's recommended procedures for safe installation. Proper setup is key to achieving the desired ride height and handling characteristics.
