Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which spring choice is best for tight asphalt club tracks?

For tight asphalt layouts you will often prefer a slightly softer spring at the rear and medium at the front to improve traction and rotation; test one step softer or stiffer to find balance.

Can I use these springs with upgraded shock caps or ride height spacers?

Yes, they work with standard shock caps and most aftermarket caps as long as the spring length and seat position match the Ultima RB7.5 shock assemblies.

How do I inspect springs for wear or fatigue?

Check for visible kinks, uneven coils or loss of free length; if the ride height or handling drifts after several runs, consider replacing the springs.
