The BD Diesel Valve Spring Kit with part number 1030060 is designed for heavy-duty diesel engine applications, specifically tailored for Dodge D250 and D350 models from 1989 to 1993 equipped with the 5.9L 12-valve Cummins engine. These springs are engineered to enhance engine performance by maintaining optimal valve operation under high-pressure conditions. Made from durable steel, they are built to withstand the intense demands of high RPM operation and severe towing duties. This kit includes replacement exhaust valve springs capable of supporting up to 60 psi of back pressure, essential when installing exhaust brakes or performance modifications. When used simultaneously with a P7100 injection pump kit, two sets of springs are required to ensure proper functionality and performance. These springs are particularly effective in increasing power output, with some applications reporting a performance boost of up to 30 percent. The BD Diesel Valve Spring Kit provides reliable operation and long-term durability, backed by a 12-month or 12,000-mile warranty, making it a trusted choice for fleet operators and diesel enthusiasts alike. Proper installation involves replacing the springs during engine rebuilds or upgrades, and it is recommended to follow manufacturer guidelines for best results to ensure optimal engine health and performance.
