"The titanium springs are full noise. I can go faster and jump higher than with stock springs."
RCS has titanium springs for your high-performance snowmobile needs. We have springs to improve your clutch performance and your suspension performance. In addition these springs save weight and resist set.
Clutch SpringsShop Snowmobile Clutch Springs
Springs are the brains of clutches, controlling how efficiently a clutch turns power into acceleration. Consistent spring performance is crucial for maximizing performance, yet clutch springs are typically the most over-stressed part of a snowmobile.
Stock and aftermarket clutch springs are made from chrome silicon wire. As horsepower has increased and power bands have narrowed it requires greater spring forces to “shift” the transmission. With many of today’s high powered sleds, the springs are just not up to the task.
There is not enough room to increase the size of wire in the spring to reach the required engagement pressures. Some of the most popular Polaris and Ski-Doo clutch springs are stressed beyond 70% of the tensile strength of the wire. At these stress levels the springs will lose length from permanent set. This problem is only made greater by the heat generated during clutch use. One Ski-Doo clutch spring, commonly used in grass drag racers, loses over 20 pounds of force at engagement in 3 full shifts. What is needed is a better material. The comparable titanium spring looses less than one pound at engagement in 200,000 full shifts.
What makes titanium the best material for highly stressed clutch springs is its combination of greater flexibility (low torsional modulus) and high strength. Effectively, this yields more force in a given space. By being more volumetrically efficient, titanium springs can be designed to operate at stress levels that do not result in spring set. Cycle tests have shown that for comparable loads, titanium clutch springs take less permanent set in 100,000 full shifts than steel clutch springs exhibit in 25 full shifts. Consistency is the key. If clutching changes, performance will drop off.
When off the shelf won't do, custom RCS titanium springs are available through select specialty dealers. These are companies who have redefined state of the art in snowmobile design.
Suspension SpringsShop Snowmobile Suspension Springs
Go beyond the limits of conventional suspension and attain the future of high-performance snowmobile suspension performance. RCS, in cooperation with several true innovators in the sport have developed titanium snowmobile suspension springs that weigh 30 to 50% less than OEM springs. With a softer initial rate for small bumps and washboard, coupled with a higher rate for absorbing the big hits without bottoming, titanium springs will provide a plush ride for the trail, but they are tough enough for use on the track.
Titanium springs can provide progressive rates without weight penalty; more travel; lower un-sprung weight; and reduced inertia, all of which combine for a more capable performance suspension system. Steel springs are often designed with very high stresses in an effort to keep weight down. Performance suffers when the spring begins to take set or yield causing setups to change and performance to degrade. Titanium's superior combination of properties alleviates these concerns by providing stable designs at reduced weights. Titanium springs can shop more energy in a given volume than steel, which allows for systems with higher forces which provides better handling at higher speeds.
