This is what you want if you already have Silver's Coilovers. Please include the kit part number you have or the specific vehicle the kit is already on in the ORDER NOTES PLEASE and if you want spring rates other than your kit's default spring rates, include that information as well please.
Swift springs are a great way to Improve ride quality and customize your coilovers spring rates.
Most coilover brands do not recommend going more than 2-4K higher or lower than original spring rates for the best damper performance. Silver's kits can generally handle a 4k rate difference with no issues.
If you are not sure which springs your Silver's kit needs, please ask and we will be happy to help!

Good deal, comes as described!

Arrived in perfect shape

When first purchasing the kit, it was very straight forward. I told them what I was looking to do, they directed me to the exact kit with everything needed included.
I recently had an issue with one of the struts, and FIP very quickly responded and handled everything with Silvers. New strut arrived at my doorstep within days.
Highly Recommend ordering with FIP.
