Front fork preload?

[audijunky]

I want to put some PVC tubing in with my springs to compress them more than stock (stiffen them up) any one know what size PVC to use?
Thanks

audijunky;

The Progressive Suspension specs state that you should use a PVC pipe that is "close to the diameter of the spring but still fits inside the fork". I now, not much help!

I think it's a 3/4" PVC pipe. I'm NOT positive, but a 1/2" and 3/4" by 6" PVC nipple should be cheap at any hardware store.

You'll also need a flat washer to go between the spacer and the spring

There's a couple of ways, one is to slide the 1 inch length spacer above the springs as usually done. Or the other way, if you might want to lower the bikes' front end down an inch at the same time, then slide the 1 inch spacer between damper rod and inner tube, results in a 1 inch lower front end, 1 inch less fork travel, and stiffer springs.

Thank you for the info fellas
