This spring is a very simple upgrade and well worth the money. The factory clutch spring in the primary clutch engages at a rather high rpm which results in somewhat of a "launch" when it grabs the belt. The soft start clutch spring we are selling lowers the clutch engagement dramatically and allows for smooth throttle transitions and eliminates the "launch" feel. Extremely handy when loading trailers and backing up.

We've tested this spring in the Apex, Vector, Nytro and SR Viper with very positive results. No loss of performance and top end. While we didn't check MPG, we've had several customers inform us of fuel mileage gains after installing the spring.
