well im searching and i found works shocks for 307 dollars. duel rate for 330 and tripple rate for 370. Whats the difference? I have a 2001 400ex and im a trail rider, and i just like to race around the track with my friends. Not competition. Any help would be good. Thanks

 

I got this off the Works site....This should help you.

Q: What is the reason for the dual- or triple-rate springs? My stock shocks only have a single spring.
A: The dual- or triple-rate springs allow the optimum spring rates for each application. These multi-rate springs are soft at the beginning to soak up the small bumps, but "cross over" to the stiff part of the rate to resist bottoming on jumps and other big "hits." The dual-rate springs have two rates, a soft and stiff, while the triple rate adds a "medium" rate in between. The application of single-, dual-, or triple-rate springs is based on the overall length of the shocks, the shaft travel, and available spring rates. Customer requirements also make a difference.
