Power Driven P-Pump Timing Kit — 1994–1998 5.9L 12v Cummins & 4BT P7100 Traditional P-pump timing with a dial gauge is slow, fiddly, and easy to get wrong. The Power Driven P-Pump Timing Kit replaces that process with a magnetic degree wheel and a dedicated timing gear puller — faster, more accurate, and straightforward enough that anyone with basic mechanical skills can do it themselves. We use this method in-house on every engine we time. What's Included 1x Power Driven Magnetic Degree Wheel 1x Timing gear puller Build Your Kit — Optional Add-Ons At checkout you can add either or both of the following upgrades: Locking Washer (+$30) — Locks the injection pump in position after timing, preventing the pump from walking out of adjustment over time. Recommended for any truck that sees performance use or regular timing adjustments. PDD Nylon Timing Pin (+$30) — Replaces the factory steel timing pin with a nylon version that won’t damage the flywheel if accidentally left in. A simple but important safety upgrade, especially if you’re timing the engine solo. Both add-ons together = $50 over the base kit price. Fits 1994–1998 Dodge Ram 5.9L 12v Cummins with P7100 injection pump Any year 3.9L 4BT with P7100 injection pump *May not work for all builds due to other engine/vehicle modifications. Frequently Asked Questions What is a P-pump timing kit and why do I need one? It allows precise adjustment of injection timing on 12-valve Cummins engines running a P7100 injection pump, unlocking more power and better fuel economy — without the complexity of a traditional dial gauge setup. How much power can I gain from advancing P-pump timing? Properly advanced timing can add 30–60+ HP depending on supporting mods, while also improving throttle response and fuel efficiency. Is it hard to use? No — it’s a straightforward mechanical adjustment with no tuning software required. The magnetic degree wheel and timing gear puller make it significantly easier than the traditional dial gauge method. Watch the full walkthrough below. This product cannot ship to California.
