Primary Clutch Springs are all about resistance. The higher the resistance, the higher the RPM engagement. Low Engagement springs are designed for smoother takeoffs and more feasible for trail riders who vary speeds constantly. High Engagement Springs, like our Shift-Tek Silver Spring, are more desired for racing and drag set-ups. This High Engagement spring was designed and tested to increase engagement to about 2200 RPM when used with Stock Clutch Weights, compared to the stock spring with an 1800 RPM engagement.
If you plan on upgrading to the EVP Exclusive 2-Step Launch Control, we recommend our Shift-Tek Essential Clutch Kit which pairs this High Engagement Silver Spring with notched weights for an RPM Engagement of about 2600.
The EVP Shift-Tek Silver Spring, when used with stock clutching will net about 2200 RPM Engagement, which is high enough to use for our EVP Launch Control programming, but we recommend our Shift-Tek Essential Clutch Kit or which pairs the High Engagement Silver Spring with notched weights for an RPM Engagement of about 2600. We also offer our Ultimate Clutch Kit which also includes a Helix.

Evolution Powersports has a reputation of the utmost quality and attention to detail on every product they design. From within the industry and outside, I have heard nothing but great things about this company and my experience has been the same. If you are looking to make more reliable power this company can get you there. Both customer service and product design are top notch and they stand behind their work!

If you truly want to build your project with the best possible parts available, buy EVO. They not only build with the best materials they test and test to make sure you are getting the performance gains they say you will but that the mods will be safe and keep the reliability of the machine as high as possible. Thanks again to both Jim and Todd. Keep it up guys!
