Ever notice when you push down on your suspension after a bunch of miles that it doesn't return to its normal ride height? This is often due to worn spring guides. Ledger Performance high-performance torsion spring guides for Ski-Doo snowmobiles reduce friction and wear from your springs while maintaining consistent preload on your rear suspension to ensure a smooth ride. They are made with a combination of high-density plastic that resists wear and aluminum to provide added strength.
