DESCRIPTION
Price is for a pair of springs.
These are linear race springs for coilovers. NOT direct replacements for your factory springs. Will not fit on shocks that take a large diameter factory type spring. You must already have a coilover that uses a linear race spring to fit these.
Swift's innovative products are the result of over 90 years of experience in industrial spring manufacturing. Their engineers have spent countless hours developing and re-developing their springs, in order to create a product that is light, durable, and compliant, while still maintaining linear spring rates. All Swift Springs are manufactured using (H5S.TW) which is far superior to silicone chrome steel and allows winding with less coils, resulting in reduced un-sprung weight and increased stroke. Note if you want to upgrade from spring rates included with any of our standard Road and Track kits, we suggest a max upgrade of 2kg in rate increase to stay within the damping control of your current valving. For example, typical ND or NC customer with our Ohlins road and track kit might consider 9kg front and 5kg rear, a nice bump up from 7kg front and 4kg rear included in those kits.
Spring selection guide for OHLINS:
NA/NB Ohlins Road & Track DFV
Diameter: 65mm front and rear / Length: 8" front, 7" rear
Spring rates in the standard R&T kit are 8kg front / 6kg rear
NC Ohlins Road & Track DFV
Diameter: 65mm front, 70mm rear / Length: 8" front and rear
Spring rates in the standard R&T kit are 7kg front / 4kg rear
When changing to race spring rates over 10kg front / 6kg rear, we typically reduce spring length by 1" and add helper springs. NOTE: NC Ohlins comes with a "beehive" shape rear spring that is 70mm at the bottom but much larger at the top. To convert to a race spring that is the same diameter top to bottom you must also get our delrin rear top hat adapters and conversion hardware, sold separately.
ND / Fiat 124 Ohlins Road & Track DFV
Diameter: 65mm front and rear / Length: 8" front and rear
Spring rates in the street version are 7kg front / 4kg rear
Spring rates in the race version are 10kg front / 6kg rear
When running rear spring rate of 6kg or more, we add helper springs to the rear, but leave the rear spring length at 8".
