1- Install the spring spacer hardware and the cap fully onto the rod.
2- Extend the cartridge. Do your best to extend the cartridge to the point where the Top-Out Spring just comes in contact.
Measure from the top of the Cartridge to the bottom of the Spring Washer. This is the Relaxed Set Length.
3- Measure the Spring. This is the Free Length
Free Length minus Relaxed Set Length is the Relaxed Preload.
4- Set the Preload using the Relaxed Preload recommendation from the Product Search or your DVS Setup Sheet.
Adjust the preload by adding or subtracting washers or adjusting the Preload Spacer Length.
NOTE: RT Springs are often a different length than stock. This is how they are designed. You will have to make your own custom spacers.
The spring should always rest on a steel or plastic washer. It should NEVER rest on the aluminum fork cap. Be sure to take washer thickness into consideration.
On many Open-chamber forks washers are added at the bottom of the spring.
The Preload Washers must be retained so they cannot shift off center. If it shifts off-center on an Upside-down fork it will damage the fork tube.
5- Double check the Actual Preload.
6- Tighten the jam nut to the fork cap on the damping rod. Install the fork cap. Set the adjusters.
