Product Details
AMSOIL DOMINATOR Synthetic Racing Grease delivers extreme-pressure bearing protection for high-speed, high-heat racing applications across dirt, snow, water, and track. Built on a calcium sulfonate complex thickener paired with a high-viscosity-index synthetic base oil, it handles the punishing conditions that destroy conventional greases.
Racing puts bearings through conditions that no street application can replicate. Wheel bearings in a sprint car running 7,000+ RPM on a dirt oval, trailer hubs on a drag car towed across the country, driveline components in a snowmobile running flat-out on hard-packed snow. These environments combine extreme speed, heavy loading, high temperatures, and exposure to water, dirt, and debris. A standard multi-purpose grease simply was not engineered for this kind of abuse.
EXTREME-PRESSURE WEAR PROTECTION FOR HIGH-SPEED BEARINGS
DOMINATOR Synthetic Racing Grease is loaded with extreme-pressure additives that protect heavily loaded bearings when speeds and temperatures spike. In ASTM D2596 Four-Ball EP testing, it achieved a weld point of 500 kgf and a load wear index of 62, more than double the minimum NLGI GC-LB requirements of 200 kgf and 30, respectively. The Four-Ball Wear Test (ASTM D2266) produced a wear scar of just 0.42 mm against a 0.6 mm maximum. For race car wheel bearings, throwout bearings, or driveline components under sustained heavy loads, that level of protection translates directly to longer component life between rebuilds.
SUPERIOR FRICTION REDUCTION FOR MAXIMUM POWER THROUGHPUT
Every bit of parasitic drag through a bearing is power that never reaches the ground. DOMINATOR Racing Grease is formulated specifically to minimize friction in high-speed bearing applications, helping maximize power throughput. Less friction also means lower operating temperatures, which extends both grease life and bearing life. For circle track, drag, off-road, or snowmobile racing, reduced bearing drag is a measurable competitive advantage.
HIGH-TEMPERATURE STABILITY THAT OUTLASTS CONVENTIONAL GREASE
The calcium sulfonate complex thickener in DOMINATOR Racing Grease provides a dropping point of 318°C (605°F) per ASTM D566 testing, far exceeding the NLGI GC-LB minimum of 220°C (428°F). In ASTM D3527 high-temperature life testing, it lasted 220 hours compared to the 80-hour minimum requirement. This means the grease stays in place and maintains its structure under sustained high-heat conditions where lithium-based greases would break down and flow out of the bearing housing.
LOW-TEMPERATURE PUMPABILITY DOWN TO -40°F
Racing does not always mean hot. Snowmobile racing, early-morning staging, cold-weather towing to the track. DOMINATOR Racing Grease has an operating range of -40°C to 177°C (-40°F to 350°F). Low-temperature torque testing per ASTM D4693 at -40°F produced a result of just 2.5, well under the 15.5 maximum. The grease flows and lubricates immediately at startup in freezing conditions instead of sitting stiff in the housing while bearings run unprotected.
RESISTS WATER WASHOUT AND CORROSION
Mud, puddles, pressure washing, rain. Racing equipment gets wet constantly. DOMINATOR Racing Grease lost only 0.5% in ASTM D1264 water washout testing at 79°C (175°F), compared to the 15% maximum allowed by NLGI GC-LB standards. Oil separation (ASTM D1742) was just 0.2% against a 6% maximum, meaning the grease stays intact and does not bleed oil over time. It also passes ASTM D1743 rust and corrosion testing, protecting steel and iron bearing surfaces even in wet, corrosive environments.
SPECIFICATIONS AND COMPATIBILITY
DOMINATOR Synthetic Racing Grease carries an NLGI Grade 2 consistency rating and meets NLGI GC-LB performance standards. It is suitable for high-speed and high-temperature wheel bearing applications (GC) as well as chassis lubrication duties (LB). It is compatible with many other grease types, though AMSOIL recommends cleaning old grease from the housing when switching products, or flushing with a liberal amount of DOMINATOR Racing Grease while the mechanism is in operation.
APPLICATION GUIDANCE
Maintain bearing housings one-third to one-half full of grease. Over-greasing causes excessive heat buildup that works against you. Wipe fittings clean before injecting grease to prevent pushing contaminants into the bearing. Periodically clean and repack housings with fresh grease on an established maintenance schedule. Available in 14 oz. cartridges.
