The power of a battery grease gun with the control of a manual.

The LockNLube DynaBoost delivers up to 12,000 PSI when pressure is required, combining powerful output with smooth, controlled operation.

Meet the LockNLube DynaBoost Dual-Mode Grease Gun, our most advanced manual grease gun yet.

Engineered for professionals who demand both precision and power, the DynaBoost is designed to adapt as conditions change, maintaining smooth grease delivery during normal operation and applying additional pressure automatically when resistance increases.

The Green Pressure Indicator Pin pops out when resistance builds past approximately 1,500 PSI, providing a clear visual signal that the gun is operating in its high-pressure range. Once resistance drops, the indicator retracts and the gun returns to normal operation automatically.

The cast aluminum head, 20-inch high-pressure hose, and included LockNLube® Grease Coupler make it a complete, leak-free system built for daily use. Designed for easy priming, quick cartridge or bulk loading, and long-term serviceability.
