Increase your driving confidence and towing safety with the superior retarding performance of the BD Brake for '89-'98 5.9 liter Cummins engines. Using BD's exclusive Variable Orifice Technology, BD's turbo-mount design bolts in place of the factory elbow between the turbo and the exhaust system, providing peak retarding power throughout the engine's rpm range not just at high rpm like other brands.
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.
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.
Automatic-equipped trucks require a torque converter lockup controller in order to electronically control torque converter clutch engagement to maximize braking to the rear tires.IMPORTANT NOTES:

Does this Brake require an air compressor and air to activate the brake?
Yes, It however is included in the kit
is this for a 4in down pipe? Mine is a 3"" turbo back, if it is a 4"" is there an adapter??
If it is a 89-93 it would require a BD downpipe specifically for that truck and brake. If it is a 94-98 the stock exhaust flange will bolt up.
I have a 1991 dodge cummins with and automatic and was wondering if and exhaust break would damage my tranny if i wasn't pulling anything? I live in a cold place and would use it to warm up my truck faster and the occasional slowing down with no load. How much damage would that cause ??
This should have no adverse effects and cause no damage to the transmission.
I currently have a 1996 dodge with the 5.9 liter cummins. I've had at least 3 Pac Brake canisters replaced @ at least a min. of $700.00 Its the vacuum system. after a length of time they seem to stick and won't come open when switched off until the engine is shut off. I would like to replace it but the cost, if I was to replace it would be over $3500.00 over the past 15 years. The transmission is automatic and if I just take it out of overdrive I seem to be able to maintain a safe down hill speed. The transmission heats up some but not $1000.00 plus. Whats your take. Our fifth wheel is 13,000 lbs.?
I would really talk to PacBrake on maybe some maintenance tips to help the cylinders last longer. You may have the same issue with the BD Brake.
I have a 1998 Ford F800 with 5.9 liter 12 valve Cummins with Allison auto trans. Would this product work on my truck as is or would I need to do anything differently than if it were a Dodge??
These may not work on that application, I would recommend shooting us or BD a call to verify fitment on this vehicle.
is the brake controlled by a button on the shifter, or is it like the new 6.7 rams where you press a button and it's constantly running until you press the button again to deactivate it??
This unit will be switch activated to be on or off.
Will this unit work on a 1998 F800 with a 5.9 12v cummins manual transmission?
No, this would not be for that particular application. For your vehicle give our sales techs a call and we can see what we can source for you.-TL
while driving from the car wash last week with my exhaust break switch on the switch under the accelerator pedal stuck on, I could on go 35 mph tops, when I got home and shut it off it ""fixed"" itself, why did the switch get stuck on and what do I do if it does this again? I have used it for many years and really like it.?
Could have been stuck from dirt. If you unplugged it the circuit would be open and it would disable the brake.-Sands
