DNJ Timing Chain Kit with Water DNJ® Engine Timing Chain Kits with Water Pump are complete timing system service kits that include timing chains, guides, tensioners, a water pump, and unless otherwise specified sprockets to restore factory-spec timing. This combination ensures both timing precision and proper engine cooling. DNJ® Engine Timing Chain Kits with Water Pump are built to exact tolerances and manufactured to meet or exceed OEM quality standards. DNJ® Engine Timing Chain Kits with Water Pump are built using premium materials engineered for durability and performance. Timing chains are made from heavy-duty steel with anti-wear treatments, while sprockets are precision-machined from hardened alloy steel for strength and accurate tooth engagement. Tensioners and guides are constructed from durable metal, polymer, or reinforced thermoplastics like nylon for stability under stress. The water pump features a cast aluminum or cast-iron housing with metal or composite impellers to ensure consistent coolant flow. All components are selected for their wear resistance, fatigue strength, and dimensional stability, with heat-treated surfaces to maximize longevity and reduce backlash under extreme operating conditions. DNJ® also offers related timing components, including timing belt kits with water pump, timing chain kits, timing covers, oil pumps, timing covers, and more. With precision engineering and top-tier materials, DNJ® Engine Timing Chain Kits with Water Pump deliver exceptional performance and long-lasting durability.
