I'm looking to do a 2" AAL in the rear, w/ new shocks. Where can I get a BPV relocation kit? Do I need one? :confused:

you basically need to extend the mount on the axle the amount of lift you are adding so for you 2". I just went and got a piece of flat steel and drilled holes in it and put it in there. Nothing fancy, whatever will do the job.

Up to 2", I've been told you don't need one. I'm not running one with a 1 1/2" AAL and have 0 problems. Try it first? Add later if needed.

Do you know what size holes, bolts are needed?

BPV Brake proportion LSPV bracket load sensing

anestech* said:
So, with a 1.5" lift, you wouldn't need a long BPV bracket?
You will need a bracket to accomodate the amount that you lifted. In your case 1.5" inches.

Technically- its the load sensing proportioning valve- This will adjust to increase/decrease rear braking based on the load in the bed-
The original bracket is located on the axle- So think of rear brake proportioning based on the distance between your rear axle & frame.
If your bed is loaded- You decrease the distance between the frame & the rear axle-
When you lift your truck , you increase the distance between your axle & frame- You want to return the end of the arm attached to the LSPV to the same position relative to the frame.

Here's a hypthetical situation....say you wanna get more breaking ability and you make a BPV valve that is LONGER than your lift. Would it think the bed is full of stuff and make the rear brakes help out more? Any downsides to this?

Yeah, the rear brakes could lock up much more easily, which could be a bad thing.

But what about just a little bit, say a 2" BPV bracket lift for just a 1.5" lift???

How would the rear brakes lock up w/ anti-lock brakes? Or is that just for the front brakes?
Well, then they would do the juddering thing, which is also not as good as braking with maximum traction. When the BPV is adjusted correctly, it tries to get the back brakes to do the maximum thay can when the fronts are doing the maximum they can, based on the weight distribution of the truck. Going either side of this unbalances it, one end reaches it's maximum braking before the other. The ABS would possibly be better stopping distance than locking up (or maybe not, maybe just controlled), but maximum braking is the best if you can achieve it.

Bpv

I wast just rambling on in another thread about this. Now that I know it goes by the name BPV I will do it here. atwinda has the best solution I've seen and I am going to put it into motion soon. However, he could probably sell this thing so if you want more info you'll have to ask him. For now I don't even have the rod in but my lines are pinched just right so I can't tell a difference. :xdevil:

Probably the best way to solve the whole problem is to remove the factory BVP and plumb an adjustable porportioning valve into the cab. Summit has 3 of them in their newest catalog, 2 made by Wilwood and 1 made by Summit.

nothing unless you go too far and have the brakes locking up to easy not to mention possible overheating the rear brakes and increased wear on the shoes.
