New Hampshire-based Welch Manufacturing Technologies—the company that makes the Biteharder carbide runner sharpening tool—released a new product for the 2017-2018 sled season: Polytune™ Suspension Rings.

Reportedly inspired by spring rubbers used in NASCAR and Formula One races, the Polytune™ Suspension Rings snap onto the coil springs of your snowmobile suspension to provide quicker response times and flatter cornering. The urethane material used in the rings is also said to dampen vibration so that at the end of the day, there’s less rider fatigue.

“This aftermarket application is quite simple,” wrote the company in an October 2017 press release. “By adding a high-tech material like our Polytune™ Rings to your suspension spring, you change its characteristics to a more progressive rate, allowing for faster suspension reaction times when needed, but also maintaining a compliant ride without sacrificing comfort.”

The rings come in three different tuning densities: soft for the casual rider, medium for the more aggressive trail rider and hard for the hardcore ditch banger. The manufacturer also says the rings can be used for ATVs and UTVs as well.
