What does the spring rate (550 lb/in) mean for my vehicle?

A 550 lb/in spring rate means that for every inch the spring is compressed, it exerts 550 pounds of force. This rate is generally firmer than stock, offering improved body control during cornering and braking without making the ride too harsh for everyday driving.

What is the inner diameter of this spring?

This coilover spring has an inner diameter of 2.5 inches. It is designed to fit coilover shock bodies that also measure 2.5 inches in diameter.

Do I need special tools to install this spring?

Yes, installing a coilover spring typically requires a spring compressor tool to safely remove and install the spring onto the shock absorber. Always follow the manufacturer's recommended installation procedures.

About this part

Product Details

This 14-inch long, 2.5-inch inner diameter coilover spring from Fox is rated at 550 pounds per inch. The spring rate is a crucial factor in how your suspension handles bumps and body roll, and this specific rate is often chosen for vehicles where a balance between comfortable street driving and capable off-road performance is desired.

Constructed from strong steel and finished in silver, this spring is built to withstand the rigors of suspension duty. The 550 lb/in rate offers a noticeable improvement over stock springs, providing better control during cornering and reducing brake dive without making the ride overly stiff for daily use. It’s a popular choice for those looking to fine-tune their vehicle's suspension setup.

When installing, remember that spring compressors may be needed to safely remove and install the old and new springs onto your coilover shocks. Always refer to the manufacturer's installation guide for specific procedures.
