Associated 5466 Differential Fluid 12,500 cSt, 2oz

This is genuine Associated 5466 silicone differential fluid, rated at 12,500 cSt and packaged in a 2oz bottle. Diff fluid is one of the most direct tuning tools you have for adjusting how your car transfers power through corners, with thicker fluids like this one adding more resistance inside the differential for a firmer, more locked-up feel.

Racers often carry a range of diff fluid weights to dial in handling for changing track conditions, and 12,500 cSt sits on the thicker end for surfaces where you want to minimize wheelspin and maximize forward bite. Associated blends its silicone fluids to a consistent viscosity, so your tuning stays repeatable from one rebuild to the next.

Since diff fluid degrades and can leak out through worn X-rings over time, refreshing it during routine differential maintenance keeps your car performing the way it was tuned. This 2oz bottle is enough for a rebuild or two.
