Contra Sport V.2 Spring Set. The current version of the Naraku rebound spring uses a modified spring alloy, providing better durability and above-average resistance. Replacing the spring is necessary when tuning your engines. It prevents initial reaction from the variator, thereby increasing the engine speed. The delayed engagement will boost power during startup. The markings on the spring help you identify its resilience.
