Spectro Differential Oil 75W90 GL5
This is the heavy-duty juice your diff’s been begging for. Spectro 75W90 GL-5 is engineered for high-load, high-heat punishment—perfect for street bruisers, dirt dogs, and oval-track addicts who know traction is life.
Extreme pressure additives? Yep. Long-life protection? You bet. It clings like drama at a family BBQ and keeps your gears from grenading when things get gnarly.
One quart. All grip. No grind.
Pour it in, drop the hammer, and let that rear end sing.
