Turn One’s HP2 Series of pumps are like a “Stage 2” upgrade over factory stock pumps. HP2 pumps come with our proprietary pump internals that are custom-designed to reduce unnecessary horsepower consumption from your engine and impart less heat into your power steering system. Additionally, HP2 Series pumps allow for custom-tuning options for high performance vehicle driving and vehicle customization. This sometimes is a necessary upgrade for vehicles that will be racing competitively, driving autocross, drifting or pushing their vehicles in other demanding environments where wheel loads are increased significantly.
