CUTTING EDGE TECHNOLOGY - Shockproof technology designed to make a big impact against big impacts

QUIET SMOOTH SHIFTING - V-Twin Transmission oil dampens transmission noise, reducing the notorious shifting clunk found in these gearboxes

IMPROVES PERFORMANCE - Transmission fluid that dramatically reduces temperature, providing thicker oil films between gear teeth and resists throw-off

Allows color matching of caps for dedicated adapters.

Cooling System fill kit prevents spills and trapped air. Trapped air pockets may cause erratic cooling system and heater performance.

5” Extension Bar and 45° Elbow allow access to caps under shrouds or at an angle.

Removes particle contaminants from the hydraulic fluid

Provides linear path for low flow restriction

Reduces corrosion and abrasion

EXTEND THE LIFE OF YOUR VEHICLE: zMAX Engine & Fuel formulas are simple and easy to use. Micro-lubrication soaks into metal surfaces, which improves lubricity and reduces carbon deposit build-up while boosting performance and protecting vital vehicle parts.

ENGINE EFFICIENCY: Add zMAX Engine Formula to gain efficient combustion resulting in more power. Use the engine treatment at your routine oil change or every 6k miles to reduce engine wear, lower emissions and keep your engine running smoothly.

FUEL CONDITIONER: Pour zMAX Fuel Formula in the fuel tank to lubricate and maintain a clean fuel injector system. It improves fuel efficiency and performance and conditions the pumps and nozzles reducing carbon residue from the valves or pistons.

CRC INDUSTRIES: A market leader that offers impeccably designed chemical solutions to maintain, protect and repair different marine, heavy-duty motor vehicles, industrial-grade engines, household tools, and electrical equipment

CRC SALT TERMINATOR: CRC Salt Terminator dissolves and eliminates any harmful salt particles and debris, leading to corrosion, vehicle damage, and rust, from different vehicle/marine engines and cooling systems

AUTO/MARINE ESSENTIAL: When used as a corrosion inhibitor or motor flush, Salt Terminator creates a protective layer around internal marine engine components, and protects them from rust and salt corrosion
