Swift Springs for BC Racing Coilovers, by Size
This collection organizes Swift Springs for BC Racing coilovers by their physical size, so you can shop directly by inner diameter, free length, and spring rate. It is the fastest way to find the exact Swift spring that fits your coilover body and delivers the rate you want. Most BC Racing coilovers use a 62mm inner diameter spring, and the 62mm Swift spring is made exclusively for BC Racing, so it drops straight onto compatible applications.
Why Shop Swift Springs by Size
A spring only works if its dimensions match your coilover body, which is why size is the right way to shop. Three measurements define fit and feel: inner diameter, which must match your coilover perch and shaft, free length, which is the uncompressed height of the spring, and spring rate, which sets how firm or compliant the ride is. Swift Springs are prized for their lightweight design, superior responsiveness, and long-lasting consistency, so choosing the correct size lets you gain that premium performance without any fitment guesswork. Browsing by size takes the trial and error out of upgrading a BC Racing coilover setup.
Fitment Notes for BC Racing Coilovers
Most BC Racing coilovers use a 62mm inner diameter spring, and Swift makes that 62mm ID spring exclusively for BC Racing, so it is purpose-built for compatible bodies. That said, some BC coilovers do not use a linear spring, so it is important to confirm your specific application before ordering. Check your coilover's inner diameter, free length, and current spring type, then match those to the Swift spring options here. If you are unsure of your coilover's dimensions or whether it uses a linear spring, our specialists are glad to verify the correct Swift spring for your setup.
