Designed for years of reliable operation, the BD Brake's rugged cast-iron housing incorporates BD's exclusive AlumiBronze bushing and piston ring-sealed, stainless steel butterfly shaft that has proven to stand up under the harsh, high-heat conditions of the exhaust environment. Actuated by a powerful, three-inch vacuum cylinder, the offset butterfly valve won't stick, and has been strategically placed in the elbow so that it won't impede exhaust flow when in the open position. The BD brake incorporates a threaded port for mounting an exhaust gas temperature probe, as well as a 1/4-inch stainless steel port that can be used to monitor the brake's retarding performance. Got a modified or twin-turbo application? BD's remote-mount or vacuum-actuated four-inch kits are an effective solution.
Controlled by a lighted On/Off toggle switch for automatic transmissions, or an optional stick-mounted rocker switch for manual transmissions, the BD brake communicates with the engine's electronic idle verification board for quick engagement. The durable air compressor included in later model kits can even be used for other applications it's that tough.
Automatic-equipped trucks require BD's programmable Tow Loc kit to electronically control torque converter clutch engagement. This addition effectively reduces slippage, resulting in peak retarding performance as well as lower transmission temperatures.

i have a 98 12-valve that needs help braking. i am pretty handy and know my way around gas engines pretty well, but not so much about diesels. my truck has a 3.5"" down-pipe, will the exhaust brake fit my truck? also, what does ""apps"" mean? its a mechanical truck (thank god), but that means it has no ""apps"" that i'm aware of. what skill level would this install be 1-10? any information you have would be valuable. Jason?
You would probably be ahead getting the turbo mount exhaust brake. Apps is accelerator pedal position sensor. It would be a small black box with a small harness going to it. It would be screwed to a bracket on the side of the injection pump. Some auto trucks had it. Would require some welding. I would say 5 skill level.
Is the exhaust brake 4in??
Yes, this is a 4"" inline vacuum style brake. -TL
