Overview
The Banks Power GBE55233 is a diesel exhaust brake for 2001-2004 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 trucks. An exhaust brake adds engine braking by restricting exhaust flow, so the truck slows with less reliance on the wheel brakes. Banks rates it at up to 12% more stopping force than standard exhaust brakes.
The unit also increases engine power when it is not in use and needs no maintenance. A computerized brake controller runs it, and it fits the Base, LS, LT, WT, SL, SLE and SLT trims.
Key features
- Up to 12% more stopping force than standard exhaust brakes
- Increases engine power when the brake is not in use
- No maintenance required, per the manufacturer
- Computerized brake controller
Using an exhaust brake on grades
An exhaust brake restricts exhaust flow to add engine braking, which helps control speed on long downgrades and reduces the load on the wheel brakes. It works best when the transmission is in a gear that keeps the engine working, and drivers usually apply the controller before the grade rather than relying on it to stop the truck. Keep trailer and load weight in mind, since heavier loads demand more braking effort.
Because the brake raises exhaust back pressure, it puts extra stress on the exhaust system. Inspect pipes, clamps and gaskets periodically, and watch for leaks, rattles or heat discoloration after long downhill runs. Wheel brakes still wear with use, so check pads and rotors on the usual schedule even when the exhaust brake is used regularly.
Before a long descent, confirm the controller works and set the level you intend to use. After the trip, let the engine idle briefly and check for any new noise. Keeping the exhaust system sound and the controller wiring secure helps the unit function as intended.
