If this photo looks like someone may have stretched a ballpoint pen spring a bit too far, you’re sniffing down the right path. The spring represents a new technology Polaris is utilizing in their premium deep snow sleds their team first discovered on mountain bikes. The patented technology creates a stronger steel spring that delivers the same ride characteristics of a traditional spring with less coils and subsequently less material. The result is a spring that is lighter than a much more expensive titanium spring. The SnowCheck exclusive spring is found on all four locations, and sheds nearly 3-pounds versus traditional springs.
