The Yokomo YZ-SSR Rear Spring Set lets you sharpen the off-road performance of your YZ-870C Super Dog Fighter with three distinct spring rates: soft, medium and hard. Swap springs to match track conditions and keep the car competitive without changing core chassis parts.
Use the soft springs when you need extra grip on bumpy or loose surfaces, select the medium springs for all-round balance, and fit the hard springs when you require precise control at higher speed. Each rate helps you dial in roll, bounce and weight transfer for better lap times.
Made to pair with the YZ-870C layout, these rear springs install easily as replacements or upgrades. They work with the stock mounting points so you can test different setups quickly between runs.
