{"title":"ABS Modulator Valve","description":"\u003ch2\u003eGenuine OEM ABS Modulator Valves\u003c\/h2\u003e\n\u003cp\u003eA failing ABS modulator valve can prevent the anti-lock brake system from releasing and reapplying pressure fast enough to prevent wheel lockup — defeating the purpose of ABS entirely. Because each valve controls brake pressure to an individual wheel based on signals from the ABS control module, a wrong or generic replacement often can't modulate quickly or accurately enough, leading to wheel lockup, extended stopping distances, and loss of vehicle control on slippery surfaces. That's why every ABS modulator valve in this collection is genuine OEM, matched to the manufacturer's original part number.\u003c\/p\u003e\n\u003ch3\u003eWhat's in this category\u003c\/h3\u003e\n\u003cp\u003eThis collection covers genuine OEM ABS modulator valves for heavy-duty trucks and equipment, including solenoid-operated valves that hold, release, and reapply brake pressure at individual wheels during ABS events, keeping the vehicle stable and steerable under hard braking.
