2005 GMC Sierra Duramax - Decel-A-Max -

2005 Gmc Sierra Duramax Pipe Adapters
We fit the supplied pipe adapters, rear band clamp, and brake clamps. We then slid the brake into place with the actuator facing the rear of the truck.
2005 Gmc Sierra Duramax Clamp Slack
We took out any slack in the clamps and aligned the exhaust brake but didn't tighten the bolts yet. Next, we clocked the Pacbrake so the actuator was nestled inside the framerail.
2005 Gmc Sierra Duramax Welding
At this point, the pipe adapter was welded in place. If you don't have a welding set, you can detach this section from the downpipe and take it to a shop for a quick weld.
2005 Gmc Sierra Duramax Drilling
We then marked the framerails for drilling so the tank and actuator switch could be mounted. We needed two holes for the tank and one for the switch.
2005 Gmc Sierra Duramax Tank Securing
After installing the fittings using Teflon tape, we secured the tank and actuator switch to the framerail.
2005 Gmc Sierra Duramax Air Line Plumbing
Next, we plumbed the air lines, with the high pressure coming from the compressor to the tank, then from the tank to the actuator switch, and from the switch to the Pacbrake. Low pressure was then returned from the brake up to the engine bay.
2005 Gmc Sierra Duramax Lower Bracket
The lower bracket for mounting the compressor was the most difficult to reach. Turning it around and threading a nut on the compressor side made things easier.
2005 Gmc Sierra Duramax Larger Compressor Bolts
The two larger compressor-mount bolts (arrow) were secured to the empty threads on the accessory drive bracket.
2005 Gmc Sierra Duramax Compressor Mounted
With the compressor mounted, we secured the air delivery and return lines.
2005 Gmc Sierra Duramax T Connection
We used a T-connection to route air from the return line to the compressor-intake line.
2005 Gmc Sierra Duramax Plug In Pac Brake Connector
We plugged the Pacbrake connection to the Duramax wiring harness; it only goes one way. We then found a good ground and connected a 30-amp fused lead to the battery jump-start post.
2005 Gmc Sierra Duramax Switch
With the brake, compressor, and air tank mounted, we installed the Pacbrake switch inside the truck's cab. Any location you can reach the switch from the driver seat is acceptable, and most people choose to mount it in the driver knee panel.
