Think again about the downhill towing disaster. If you can relate...whether you're pulling a load that is twice the gross weight of your truck, or you're being pushed hard by the tow behind your motor home, you simply do NOT have adequate brakes. U.S. Gear's Super Duty D-Celerator unit, with it's patented waste gate by-pass port adds the safety, drive ability, and brake-saving benefits you must have to control downhill speed. Not to mention the performance necessary for the climb back up!

An oversize nodular iron housing consisting of two stainless-steel butterflies (one large, one small) is added to the exhaust system in front of the muffler. The large version is in the main passage, while the small butterfly operates in a separate waste gate by-pass port. Available from 4" down to 3" as either air or electric. When signaled, the large butterfly closes, creating immediate exhaust pressure for assisting the vehicle's regular brakes. Exhaust flow is now directed through the small by-pass port and released by the small butterfly at a pre-determined pressure (Due to this design feature, no orifices are necessary.). This allows pressure to generate more efficiently and maintains it longer, providing precision braking whenever you need it. Does not require valve spring changes or engine modifications.
