DDP 34KGSK 3000 & 4000 RPM Governor Spring Kit – 1994-1998 5.9L 12-Valve Cummins P7100

Unlock more power, smoother drivability, and higher-RPM fueling in your 2nd-gen 12-valve Cummins with the Dynomite Diesel (DDP) 34KGSK Governor Spring Kit.

Factory P7100 governor springs begin cutting fuel as RPMs rise, causing a noticeable power drop when you need it most. This kit replaces them with high-quality springs that let you choose either a 3,000 RPM or 4,000 RPM limit, allowing the injection pump to keep fueling longer. The result is stronger mid-range and top-end performance plus improved everyday drivability.

Key Benefits

• Choose 3,000 or 4,000 RPM fueling — install the springs that match your goals
• Eliminates the factory fuel cut-off for better power delivery
• Smoother gear changes, especially noticeable on manual-transmission trucks
• Holds gears longer and reduces the “fall-off” between shifts
• Easy installation on the P7100 pump
• Works with all P-7100 applications, including 4BT

Recommended Use

The 4,000 RPM springs are best suited to 215 hp or modified 180 hp pumps. When running the 4K springs, Dynomite Diesel recommends heavy-duty valve springs and maintaining at least 20 PSI fuel supply pressure at wide-open throttle.
