I just got done installing a set of Pacbrake bags on my SRW 3500. What is the best PSI to run unloaded? Will they help with freeway chop or just loaded leveling?




Install was pretty easy. I misread and did not install two lock washers on the tops of the bags so that took extra time to re-do. I'll do a compressor/wireless set up in the future. Right now, I did the license plate schrader valve method as recommended in the instructions.

Mine say 10PSI min. I was just wondering if they would help with the rough ride on the highway if I ran a certain PSI.

You know what will smooth out that choppy ride?
Weight.

Put some weight in that large cargo area we call a box, try around #300lb.

After all it is a truck, if it had a soft ride it would be a car.

I have been shopping for pacbrake bags and ended up talking to a rep from the Pacbrake company. He said 5-10 pounds is the minimun...even though the instructions say 10 pounds.

As mentioned...as long as you run enough to keep the bags from rubbing together you should be fine.

Ran 10 PSI on the freeway today and felt no difference over stock. Not that I put them on to soften the ride, but was hoping it would help a little. No worries.

Thanks for the info gents.
