8844901170 is a genuine Wabco air system exhaust brake, sold by Pro Gear and Transmission as a single unit with package dimensions of 12.00 x 7.50 x 4.25 in. An exhaust brake works by restricting the exhaust, which raises back-pressure so the engine works against itself and helps slow the truck. The restriction is normally a butterfly-style valve in the exhaust path, downstream of the turbocharger when one is fitted. Call us with your engine and truck details to confirm proper fit.
