Rear shock absorbers take a massive beating during aggressive off-road riding, creating extreme thermal loads that can cause standard petroleum-based fluids to thin out, foam, and fade. Maxima Synthetic Racing Shock Fluid is a 100% full-synthetic, ester-based oil specifically formulated to withstand the tight tolerances and extreme temperatures demanded by professional racers and hardcore adventure riders.
By utilizing regenerative synthetic polymers, this 3WT (Light) shock fluid delivers an industry-leading ultra-high Viscosity Index (over 350+). This ensures that the oil maintains its structural film strength and resists mechanical shearing, drastically minimizing the rate of viscosity change as your shock heats up over miles of desert whoops or rocky singletrack. Advanced friction-reducing additives actively decrease seal drag (stiction) for a highly responsive, plush feel across choppy terrain, while the ultra-clean chemistry eliminates corrosion and conditions internal seals to extend equipment life.
Ester-Based Synthetic: 100% full-synthetic formulation designed for maximum performance and protection under the most severe loads.
Ultra-High Viscosity Index (350+): Maintains structural film strength and resists mechanical shearing, completely eliminating shock fade caused by extreme heat.
Anti-Stiction Additives: Advanced lubricating agents significantly reduce internal running friction and seal drag for incredibly plush small-bump compliance.
Foam Prevention: Active chemistry minimizes foaming and air entrainment to ensure consistent hydraulic damping performance under high-speed shaft velocities.
Low Thermal Expansion: A minimized thermal expansion coefficient prevents increased fluid volume and internal pressure spikes under high temperatures.
Universal Compatibility: Safe for use in steel or aluminum-bodied shocks and fully compatible with both petroleum and synthetic suspension fluids.
Universal Shock Application: Ideal for servicing modern rear shock absorbers on dirt bikes, adventure motorcycles, ATVs, UTVs, and street bikes.
Viscosity Rating: This fluid is designated as 3WT (Light) with a 75/390 SUS/VI rating. Always verify your specific suspension valving and manufacturer recommendations for fluid weight before servicing.
