I was just wondering. If anyone nows the difference in performance of the two, please specify.

 

Also if you have tried one of them, but not the other, tell me about the one you have experianced.

 

when I talked to Rick at RCR, he said that the HPD plain spring engages at a lower rpm than the Polaris green spring. While I have not used the green spring, some others on this list have mentioned that makes for a pretty aggressive take off, which you may not want in tight woods or situations.

Good luck,

I just put a green spring in. And it does take higher RPM to get it going. I've only had it in the wood trails once. It's going to take some getting use too. When I finished putting it in, I just had to try it,(about midnight). Got on, gave it gas and the darn thing didn't want to move. Had to give it alot more gas, than I did prior to the stock spring.
As far a take off--if your on hard pack, it'll bring the front end up with ease. In sand it seems to spin alot easier, not sure I like that.
As for the plain spring, it's going to take alot more RPM than the green spring. I really don't think you would want that for tech. riding.
Looking at the spring chart, It takes about 42#'s of force to start engaging the green spring, and it takes about 75#'s to engage the plain spring. Which in tern means ALOT more RPM's.
Hope this info helps. In either case enjoy.
