Progress Technology Series I Coilovers
Competition Series I kits are steel-bodied shocks that are fully re-buildable. All components of the Series I kits are manufacturing in the US and they are re-built right here at our Anaheim facility. The aggressive tuning is ideal for superior street performance and autocross applications. Our exclusive take-apart dampers are tunable and rebuildable; in addition, the threaded steel bodies are plated with attractive corrosion-resistant electroless nickel. Another benefit of the Series I kits is that we can custom valve the dampening levels and spring rates for a wide range of specialty street & track applications such as autocross, road racing, and drag racing.
With no fancy knobs or colors, these coil-over kits give you everything you need and nothing you don't. If you want an out of the box kit that will transform your cars handling, look no further. Custom spring rates are available!
These kits are under warranty for one year from the date of purchase. The owner must show proof of purchase for any warranty claim.
