Bilstein 5125 9.24" travel 360/80 valving

[scoots90245]

Anybody try these with ORD or TC front springs in the AUX position.
My 255/70 seem too light for My 2" TC springs and My plan is to move up to 2" ORD springs after summer, so rather than go Quad fronts I'm thinking stiffer valving?
Thanks.
PS
Is this steel spacer/bushing stock?
