- Made in the U.S.A. and Europe
- We DO NOT sell Asian made springs
- Most of our competitors have their springs manufactured in Asia
and the wire quality and fitment is poor and they all test softer than stated
(for example: .46kg/mm springs test .45kg/mm)
NOTE: Large sizes (.60KG/mm & up) may require machining the black plastic spring guide.
To install oversized (higher spring rate) springs on open chamber style forks that have a spring guide, the guide must be machined to fit the smaller inside diameter of higher rate springs. Larger wire diameter is required to increase the spring rate. Because the O.D. cannot be changed, the larger wire makes the I.D. smaller which creates the fitment issue. The spring guide is designed to fit only the OEM springs, therefore you must machine the guide. If you want to use stiffer springs, there is no option except machining the guide. We have a video showing explaining the process. https://youtu.be/uo5NSJI3M60
Fits: See fitment tab above
Note: The European manufactured springs are rated in Newton Meters (N/mm) and the American manufactured springs are rated in Kilograms (kg/mm)
