HiCalibre Fork Springs 43.5 x 350

Manufactured in the USA from the highest grade Chrome Silicone wire. All springs have their rate engraved or etched on the ends. Spring rates made in very low volumes do attract a higher price. Please take not when ordering. Delivery from the USA for backorders is always air freight with a 2-3 week turnaround. Special order springs will take 3-4 weeks.
