TriboDyn Moly-5 is a high-performance 5% molybdenum disulfide grease designed for extreme pressure applications. It delivers outstanding protection under heavy loads and shock conditions, making it ideal for wheel bearings, U-joints, fifth wheels, and other high-stress components.
Available in a convenient 8oz jar, Moly-5 is perfect for smaller jobs, maintenance kits, and spot lubrication. It performs reliably across a wide temperature range from -22°F to 400°F, resists water washout, and meets NLGI GC-LB specifications.
Key Benefits:
- Contains 5% molybdenum disulfide for superior extreme pressure protection
- Handles up to 620kg weld load
- Performs in temperatures from -22°F to 400°F
- Resists water washout and corrosion
- Reduces friction and wear under heavy loads
- Suitable for heavy equipment, construction, mining, and agricultural applications
Recommended Applications: Ideal for wheel bearings, U-joints, fifth wheels, chassis points, and other high-load components in trucks, heavy equipment, construction, mining, and agricultural equipment.

Why TriboDyn Moly-5 Outperforms Ordinary Grease
Extreme Pressure & Film Strength
Typical greases fail at around 400 kgf on the Four Ball EP Weld Load test. Moly-5 delivers 620 kgf — over 50% higher load-carrying capacity. This means far better protection against shock loads, heavy pressure, and metal-to-metal welding in pins, bushings, and bearings.
Superior Water & Washout Resistance
Ordinary greases wash out easily in rain, mud, or pressure washing. Moly-5 has a maximum 5% loss in the Water Wash-Out test — staying in place far longer and protecting your equipment in the harshest wet conditions.
High-Temperature Stability
Most greases soften or melt under high heat from brakes and heavy loads. Moly-5 has a dropping point of 500°F (260°C) minimum and maintains structure up to 400°F in continuous use — giving you reliable protection where ordinary greases fail.
Extended Equipment Life & Less Downtime
The combination of 5% moly, superior adhesion, and mechanical shear stability means Moly-5 lasts longer in service, reduces wear, and cuts maintenance frequency — giving you more uptime and lower overall costs than standard greases.

Frequently Asked Questions
Moly-5 is a premium lithium complex grease fortified with 5% molybdenum disulfide. This high moly content creates a tough, slippery solid lubricant film on metal surfaces that provides superior extreme-pressure and shock-load protection where standard greases fail.
Moly-5 is engineered for the toughest heavy-duty uses: pins, bushings, bearings, chassis points, fifth wheels, king pins, and sliding surfaces on construction equipment, mining machinery, agricultural equipment, trucks, and commercial fleets.
Moly-5 performs reliably from -22°F to 400°F (-30°C to 205°C) with a dropping point above 500°F (260°C). It maintains its structure and lubricating properties even under high operating temperatures from brakes and heavy loads.
Yes. It meets or exceeds NLGI GC-LB specifications (the highest rating for automotive wheel bearing and chassis greases), making it an excellent choice for both high-temperature wheel bearings and general chassis lubrication.
Moly-5 is compatible with most other lithium complex and conventional greases, so you can safely top off or transition during regular maintenance. All TriboDyn greases are proudly formulated and manufactured in the United States in our own ISO 9001 certified facility.
