BD Variable Vane Exhaust Brake 08-10 6.4L Powerstroke
For diesel owners that do any kind of towing, having a good exhaust brake is not only a luxury, but a necessity. Unfortunately, for owners of any vehicle produced after January 1, 2007, installing an exhaust brake can potentially void your warranty and will not work properly with the emissions equipment on these vehicles. For 6.7L Dodge owners, they are fortunate enough that Dodge integrated a unique type of exhaust brake that merely controls the turbo to create back pressure. For 6.4L Ford owners, they have a similar type of turbo, but Ford never built in the programming to simply control the turbo to act as an exhaust brake. However, BD has changed this.
BD utilizes the variable vane technology by electronically closing off the turbine vanes which can create up to 130 retarding horsepower. This braking force will help to maintain your speeds on descents and curves, giving you better control of your truck and load.
The rotary switch offers three different modes:
- Stock
- Vane Control Only
- Vane Control WITH Aggressive Downshift
