I have for sale one PAIR (2 total) of swift assist springs w/accessories. The part number is in the second picture if you want to look it up. I know they are 60mm inner diameter and 72mm length. 4k is the spring rate...these will work with pretty much any coilover setup that has a 60 or 62mm inner diameter spring...I have provided a link above for further reading on the product.
These normally go for about $140+ from vendors. I'm asking for $100 shipped obo to the conti USA. For locals, I'm willing to drop the price for pick up. Location is 562 area code socal.
