True Performance Motorsport combines our 61mm to 65mm conversion adapter with the Swift Springs Thrust Sheets to give you only the best when changing spring rates on your KW Suspensions coilovers.
Our poly adapter allows you to upgrade the soft spring rates that usually come standard on KW Suspensions kits to any 65mm Swift Springs. This simple product eliminates your need to machine the perches. Save time and money!
The Swift Springs Thrust Sheets have a self lubricating poly sheet combined with a stainless steel shim for each spring contact surface. This significantly increases the life of the Poly adapter. These sheets not only reduce bind and unwanted preload, but they also reduce noise. This all works by allowing the springs to rotate under compression.
Comes with 4 poly adapters, 4 poly sheets and 4 stainless steel sheets. For 2 springs.
