INTRODUCING LOADLEASH : THE ONLY ENGINE BRAKE FOR 5.9L CUMMINS ENGINES

[TDRadmin]

[RAW]As the only engine brake available for the class 3-5 truck market, Pacbrake's P59 LoadLeash provides big-rig engine braking performance when used in tandem with an exhaust brake. In addition to enhanced vehicle control and reduced brake fade, Pacbrake's LoadLeash can extend service brake life by up to 500%.

​

With decades of experience in manufacturing engine brakes, the engineering behind LoadLeash is no different from the rest of the engine brakes designed by Pacbrake.
Pacbrake's Loadleash allows you to drive your fully truck with confidence and peace of mind.
Applications:

• P55006 : 2003 - early 2006 for Dodge 2500 / 3500 with a 5.9L ISB Cummins Engines (Standard Transmission).
• P55007 : late 2006 - 2007 for Dodge 2500 / 3500 with a 5.9L ISB Cummins Engines (Standard Transmission).

Product and Kit Features :

• Lightweight support housing replaces the factory valve cover spacer with no valve cover height increase.
• Modular Engine Brake Control Component that is easily serviceable
• Precision cast aluminum valve cover spacer
• Intelligent controller and IP67 rated controller housing
• Forged heavy duty bridges
• Automotive grade wiring with abrasion protection
• SAE & ISO rated fittings
• SAE rated hose

How does the LoadLeash work?
It functions by holding the exhaust valves slightly off the seat during the complete engine cycle, with the exhaust brake providing exhaust back pressure. Two braking cycles are achieved:

1. The first braking cycle is accomplished during the exhaust stroke when the piston is pushing the cylinder pressure past the open exhaust valve against the “closed” exhaust brake.
2. The second braking cycle occurs during the compression stroke with the piston is pushing the cylinder pressure past the open exhaust valve against the “closed” exhaust brake.

The expansion stroke is eliminated by the open exhaust valve. With work being done on both the compression stroke and exhaust stroke we are now doing retarding work on two engine cycles.

Driving Impressions: “Seat of the pants” feel is noticeable, particularly above 2500 RPM with a heavy load. Manual downshifting may be required. The LoadLeash is stronger at all RPMs and in most cases will control the vehicle/load in a chosen gear without the rapid downshifting and high engine RPM experienced with the exhaust brake use alone.

will it work with a auto 05 3500

No, manual only, per the article.....

will it work with a auto 05 3500

This is what I got back from the company on this very question (automatic): "The Automatic trucks need different electronics than the standard transmission. I believe they are working on an automatic version now. I have added this to our new products requests log. Feel free to contact us anytime for an update."

So if you have an auto, please email or call them and let them know you are interested and maybe they will speed up the release (or work harder!)

Exhaust brake for an automatic transmission, yes. For a manual, no. I have an 03 six speed with 341000km and never had an exhaust brake! I pull hay, horses, and a travel trailer and have only replaced brakes twice and still on original clutch. Believe me or not I don’t care but you can do without a exhaust brake if you know how to drive!!

That depends heavily on the topography you are driving through.

In Switzerland the Exhaust Brake is Mandatory on heavy Vehicles for that reason.

I can see that...however a one ton I wouldn’t really consider heavy! Yes they can pull thirty some thousand pounds but you need to consider that...heavily. it’s only a pickup and should you really be pulling that much with a pickup??...can you stop that much with a pickup? Let’s face it stock and after market exhaust brakes are not 30000 lbs effective! An actual jake brake?? Yes!! For sure but that’s a highway tractor equipped with proper engine brake and heavy trailer brakes on all axles! Not trying to argue just like a good discussion.

For me, it is like AC. I can certainly live without it here in CO, but it makes summer days much more comfortable. I towed through the CO mountains for 5+ years before getting an E-brake, but now that I have it, I wouldn't want to tow without it (of course, I also have the automatic). If and when Loadleash is made avail for an auto, I will get one.

Believe me or not I don’t care but you can do without a exhaust brake if you know how to drive!!

But since they are available why would you? I have three Cummins powered pickups, all with manual transmissions and all have exhaust brakes. They are the best money you can spend if you tow heavy. This canyon is about 10 miles across. I just hauled a 25K GCW load across it two days ago. 3rd and 4th gear down and 4th up. To get to Phoenix where I live, 5800' elevation, I climb to 7800' then descend to 1500' with several mountain ranges in between. I love my exhaust brakes!
