Question) Hi Joe, do you have a kit for me?
Answer) Hello. Please scroll down to see if your model is listed
Then - click on Build a kit

Low Elevation Trail kits are for 0'~3000' elevation. (0M~900M)
Click on the highlighted description for illustrations.
These kits are designed for use with the HPV27 secondary & helix .
The kits are not for the Formula helix which is 3.75" (95mm) diameter.
Take note for years 1999~2003 there are some models that come with the formula helix.
If you are not sure what you have, you can go to the sled and check the secondary, the model you need has an " Adjustment ring cam " with 3x 10mm bolts to hold the ring locked.
There are 6 notches on the sheave for deflection adjustment.
If still not sure what you have, then remove the secondary and measure across the diameter of the helix, it should be 4.25" (108mm) inches diameter

Sorry no 500/600/1200 clutch kit available at this moment.  As soon as I can, I will be starting to work on the 600/1200 (SUMMIT) models.
