It delivers up to 62% less wear, unmatched shear stability, and stage 14 load capacity, perfect for heavy-duty, off-road, and racing use.

  • Slash maintenance costs with 750,000-mile drain intervals for highway trucks
  • Cut wear by up to 62% versus OEM specs for longer gear life
  • Maintain peak performance with unrivaled shear stability under extreme torque
  • Start reliably in -60°F cold for all-season dependability
  • Protect limited-slip differentials and hypoid gears beyond API GL-5 standards

Extreme longevity with 500K-750K mile drain ratings. Superior anti-wear and extreme pressure protection. Excellent shear stability and load-bearing capacity.

Premium synthetic formula commands higher upfront cost. Overkill for light-duty vehicles with short drain needs. Viscosity best suited to specified heavy-duty applications.

TRIAX Synergy Gear Max 75W-90 GL-5 is a PAO and esters-based lubricant for gears, differentials, and manual transmissions, delivering up to 500,000-mile drain intervals in heavy-duty trucks and cars. Its exceptional wear control and EP/AW performance exceed OEM specs, making it ideal for highway trucks, off-road vehicles, and racing.

  • Ultra-long drain intervals up to 500,000 miles reduce maintenance frequency and costs
  • Superior protection outperforms 99% of gear oils, preventing breakdown under extreme loads
  • 62% less wear than OEM specs for longer gear and differential life
  • Exceeds highest EP and AW tests for reliable performance in hypoid and limited-slip systems
  • Versatile compatibility with heavy-duty trucks, passenger cars, off-road, and racing applications

Exceptional load-bearing capacity prevents pitting and scuffing. Nearly shearless formula maintains viscosity over extreme distances. Proven in both limited-slip and non-LS gear systems.

75W-90 viscosity may not suit all climate or lighter-duty applications. 1-gallon size best for bulk users, less convenient for small top-offs. Premium formulation targeted at heavy-duty rather than everyday light vehicles.

TRIAX Premium LS 80W-90 GL-5 Gear Oil - Limited Slip Ready for Differentials, Transmissions, Hypoid Gears (1 Gallon)

  • Delivers unmatched shear stability and oxidation resistance for extreme severe service conditions
  • Includes optimized limited slip additive—no extras needed for wet brakes or LSDs
  • Provides superior scuffing and gear protection exceeding 120,000 lbs/sqi for longer component life
  • Maintains film strength under high heat, loads, and shear without viscosity breakdown

Exceptional thermal stability and load capacity. Built-in LS additive simplifies use in limited slip systems. Outstanding protection for gears and synchronizers.

Best results require verifying specific OEM specs despite wide range. Thicker viscosity may not ideal for extremely cold climates without warmup. Primarily suited for manual and hypoid systems, not automatics.
