Swift Springs' innovative designs have made us a staple in the performance tuning world. Our products are the result of over 90 years of experience in industrial spring manufacturing. Our engineers have spent countless hours developing and re-developing our springs, in order to create a product that is light, durable, and compliant, while still maintaining linear spring rates.
Many enthusiasts will swap springs from brand to brand with the only noticeable difference being a stiffer or softer ride. But what if a spring could offer a noticeable increase in traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable feel? The engineers at Swift have taken that "what if" and turned it into reality.
All Swift Springs are manufactured using (H5S.TW.) which is far superior to silicone chrome steel and allows us to wind our springs with less coils, resulting in reduced un-sprung weight and increased stroke
Since the metric system is used widely in the sport compact and road race market, we have introduced the metric line of coilover springs to reduce confusion and to better cater to our customer's needs.
Our metric coilover springs come in various sizes with inner diameters ranging from 60mm (2.25in) to 70mm (2.75in), spring lengths from 127mm (5in) to 280mm (11in), and spring rates from 3kg (168lbs) all the way up to 34kg (1900lbs). Whether you are looking for a comfortable ride for your commuter or a more aggressive setup for your race car, we have the right spring for your application!

QUESTIONS & ANSWERSAsk a Question
Are the springs made to order to fit my coilover setup? I have a 2013 camaro Ls and I’m looking for smaller springs with more stiffness to lower the car a little more. Is 34k springs good enough with 4 inch springs or what would be recomended for dropping it another say 3-4 inches
The springs are determined based on inner diameter, spring rate, and length. Just provide us your vehicle details when ordering and the setup you need.
Do y’all carry 40k swift springs
We carry 326power.
What size spring will come with these, it only gives me option for the spring rate not the size of the spring?
When placing the order there's a field to designate your vehicle. In that field, let us know the the vehicle year/make/model and model (ie: 2012 Lexus IS350 RWD). Also, use the dropdown to select the model of coilovers they are for. From that information, we will determine the correct spring size needed.
