Zacker Core is a thermoset polyurethane coil spring buffer engineered to improve ride comfort, enhance vehicle stability, increase ground clearance and provide additional suspension support. Designed for Indian road conditions, it helps reduce excessive body roll, improves load carrying capability, minimizes suspension bottoming and contributes to longer suspension life. Unlike other thermoplastic polyurethane or rubber buffers, Zacker Core is manufactured using durable thermoset polyurethane for long-lasting performance and shape retention. It installs easily between the coil spring across all sedan/hatchback/SUV/MUV without permanent modification and is suitable for daily driving, highway driving as well as vehicles that frequently carry passengers or luggage.
