Progressive rate rear shock springs with 1.5" ID. Use adapters to pair with shocks utilizing spring seats and preload collars with differnet dimensions. Spring rates progressively climb to 20-25% at max compression. Perfect for suspension designs that lack inherent progressivity or simply for additional support and less reliance on high-speed compression damping and/or other bottom-out control systems. Make sure the stroke length of our Progressive Springs are equal-to or greater-than the stroke of your shock.
Progressive Springs are suitable for shocks with 47.5-65mm of stroke. If you have a 47.5 - 55mm stroke shock, and a 55mm stroke Progressive Spring is available in your preferred spring rate, select that option to maximize progressivity and ensure fit. Some fitments will require spring adapters.
