This is a trailer brake control (TBC) valve that modulates air pressure to the trailer service brakes in proportion to the control signal from the tow vehicle.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It is made of engineering-grade composite for lightweight, corrosion-resistant performance and includes an integral anti-compounding feature to prevent service and spring brakes from applying simultaneously. An exhaust cover keeps out road debris and inlet filters reduce contamination to extend service life. Replace this valve when you notice leaking air, slow brake release, or inconsistent trailer braking to restore reliable operation.
