Fellow Rammers:
I just "engineered" a modification for my rear brake load proportioning valve to adjust brake pressure for rear brakes.
I have Air Lift aux air suspension on the rear of my truck. In empty mode, truck sits 1/2 inch higher than stock, making brake load proportioning valve think the truck is lighter than it is. And when I have 5th wheel with 3200 pin weight, I set truck level with airbags, making proportioning valve think truck is way lighter than it is and applying minimum pressure to rear brakes.
So here's what i did. I removed fastener from bottom of proportioning rod (where it connects to axle). I took a 3 inch angled piece of steel that has pre-drilled holes and extended the rod over an inch (WAG engineering).
Brakes worked great loaded and real good unloaded. Wished I would have done this sooner. Airlift and the other companies ought to offer the extension piece for the proportioning valve so you don't lose braking capacity on the rear wheels after installing their product.
Happy trails,
Wiredawg
