So, Aye or NayOriginally Posted by MudRunnerTD
So the concept of the flexi coil is that when its off the car it is a Long Spring. Side by side with say a tough Dog spring it would be equivalent to a 5" tough dog spring for unloaded length.
Being a flexi coil though, when loaded with vehicle weight the top 3 or 4 coils of spring are fully closed and stacked on top off itself waiting to be used. This means though that the spring is now restricted in its compression by the space left between only half it's stack because the rest is closed. But the concept is restrict compression anyway as they are marketed as a super long spring and your shocks can't cope with much compression as above anyway.
So when they are unloaded (drooping due to cross flex of the axle) they extend to their unloaded extra long length without disengaging from the spring tower limiting the need for drop out cones or spring retainers to hold the springs in when your Super Long 6" shocks are now aloud to use all that open length and you get good flex.
