American Suspension coil springs are manufactured to our specifications in the USA using the finest quality, high tensile, wire available. American Suspension springs are specifically wound for road and race motorcycle applications, not repackaged car springs. American Suspension spring rates, wire diameters and coil lengths have been developed through extensive real-world testing on all types of roads and conditions. Our race winning designs have been put to the test in the heat of battle from Laguna Seca to Daytona.
All springs have closed and ground ends to sit flat and deflect true. We have the perfect spring to match your application. 
We offer a lifetime warranty to the original purchaser against sagging and breakage. You will have the added peace of mind knowing you’re covered, just in case. In the rare occurrence that a spring does fail, it will be cheerfully replaced with no questions asked. Our customer support is second to none just like the quality and performance of our products.
No bike can expect to handle well if it has the wrong springs and preload up front.  The American Suspension kit lets you easily adjust spring preload and a wide variety of springs and rates.
 
We offer spring preload adjuster caps to set your bike up taller than stock without buying new fork tubes.  The caps are available in +1”, +2” and +3”.  Get the ground clearance you desperately need and the spring rate you want.
 
Easily adjust your preload for variation in road and rider weight.

1 pair of preload adjusters
