What shock oil viscosity pairs well with these springs?

For a balanced feel start with medium weight shock oil and adjust thicker for more body control or thinner for faster initial response, testing one step at a time.

Are these springs progressive or linear in feel?

They exhibit a linear rate suitable for precise tuning; any progressive characteristics will come from spring seat spacing or additional shims.

How should I store spare springs to avoid corrosion?

Keep them dry and clean, store in a sealed container and avoid contact with solvents or salt air to preserve finish and rate.

Can I mix these springs with other brand shock components?

Mixing is possible if dimensions and seating are compatible, but verify free length and spring diameter to ensure correct operation within Ultima RB7.5 shocks.
