LockNLube DynaBoost® Dual-Mode Grease Gun
SKU: LNL81363
The power of a battery grease gun with the control of a manual.
The LockNLube DynaBoost® delivers up to 12,000 PSI in high-pressure mode and twice the flow of standard pistol-grip guns in high-flow mode, all automatically with no switches or settings to change.
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® automatically switches between High-Flow and High-Pressure modes as you work, so you can clear clogged fittings and keep grease moving fast with one tool.
The green High-Pressure Indicator Pin pops out when resistance builds past 1,500 PSI, signaling that the gun has switched to high-pressure mode. Once the blockage clears, it retracts and returns to high-flow output automatically.
The cast aluminum head, 20-inch high-pressure hose, and included LockNLube® Grease Coupler make it the most complete, leak-free system in its class. Designed for easy priming, quick cartridge or bulk loading, and long-term serviceability with genuine LockNLube® rebuild kits.

LockNLube DynaBoost® Dual-Mode Grease Gun
Overview
The LockNLube® DynaBoost® Dual-Mode Grease Gun combines the precision of a manual tool with the power of an automatic system. Built for professionals who grease daily, it automatically switches between high-flow and high-pressure output as conditions change, delivering up to 12,000 PSI when fittings are blocked and twice the grease per stroke when they are not. No settings to change. No wasted effort.
How It Works
Inside, the DynaBoost® features a patented dual-piston system that senses back pressure and adjusts instantly.
When a clog is detected, the green pressure indicator pin pops up to signal that the gun has entered high-pressure mode. Once the blockage clears, the pin retracts and returns the gun to high-flow mode automatically. This intelligent design ensures smooth, efficient greasing without switches or adjustments.
Built to Last
Constructed with a cast aluminum head and heavy-gauge steel barrel, the DynaBoost® is engineered for years of daily use. Every critical seal, spring, and O-ring is replaceable with genuine LockNLube® service kits. The included LockNLube® Grease Coupler and Loop & Lock® Storage System keep your workbench and tools clean with no drips or mess.
Compatibility
The DynaBoost® accepts standard 14 oz. cartridges, bulk fill, or filler pump loading, and handles grease up to NLGI #2. Its 20-inch high-pressure hose and inline swivel provide the flexibility to reach fittings in tight, awkward spots with total control.
