Bus, RV, Fire & Rescue
Whether your engine powers a bus, fire & rescue vehicle or RV, the genuine Jake Brake brand, Jacobs Exhaust Brake saves you time and money spent on your vehicle. Fleets and private owners appreciate the added vehicle control while making downhill descents and navigating stop and go traffic.
Utility & Towing
Utility and towing vehicles are powered to handle the toughest loads and roads- that is why they need the Jacobs Exhaust Brake. The legendary design, and durable and reliable construction will keep your foot off the service brake and save your service brakes for when you need them most.
How it works
Unlike gas engines, diesel engines produce no vacuum when you lift your foot off the throttle. Even without fuel, the engine takes in air, compressing it in the cylinders and continuing to power the vehicle. The Jacobs Exhaust Brake® mounts in the exhaust system of the vehicle, and restricts exhaust flow when activated. This supplementary braking system helps to slow your vehicle. This slowing power is achieved by restricting the flow of exhaust gases and increasing backpressure inside the engine. This increased backpressure creates resistance against the pistons in your engine, slowing the crankshaft's rotation and thereby slowing your vehicle. Overall, you use your service brakes less, they last longer and save you money.
