American Suspension was the first screw type preload adjuster.  See our 1997 patent for details.  Lots of other comapnies have copied us, and they will always be second best.  Adjust preload and make your bike sit 1, 2 or 3 " Taller without buying new tubes

There fit 49mm fork tubes.

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.

 

Like all American Suspension parts Made in the USA.

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.
