Hey
I read somewhere, and of course I can't find it again, about someone installing the HD springs and when they installed the new LPSV, they used the top holes, which is for the 3" kit when they only had the 1.5" coils. Think they said they had better braking power to the rear. Does this sound like a good idea?
Would the braking be so harsh as to lock up the rear tires first rather then the fronts? which i hear leads to uncontrolled spinning.
Jus lookin for some advice, getting my springs this weekend and wondering if it would be an easy "break upgrade" to position the bpv to the top holes. I'll keep lookin for that tech article.

Thanks guys

Steve

 

If it were me I'd want it as close to stock as possible. However, having said that, All Pro just ties the lever up to the frame, but their reasoning is that with huge tires the tires are less likely to lock up. Also, most likely you have at least rear antilock brakes.

I'd stick with what downey says to use, myself.

 

"Install the drop bracket for the LSPV. The LSPV adjusts the amount of braking power to the rear, based on the amount of weight the vehicle is carrying. The more weight, the lower the vehicle sits in relation to the axle, and more braking force is applied to the rear brakes. When you lift the vehicle, the LSPV thinks there is less load, and reduces the amount of braking to the rear. The drop bracket tricks the LSPV into thinking you are at stock height. The Downey bracket allows two settings; the lower setting is for the 1.5" coils, and the upper setting is for the 3" kit (1.5" coils plus 1.5" spacers). We actually used the upper setting, which provides some really nice braking."

thats all that is said about what he did, but he did it. I think I'll do the same when i do my install and see if there are any adverse effects. I'll let you know how she handles afterwards.
If you got some input, feel free to share

I did the middle position on mine and the braking seems good. Perhaps I'll try the 3" position and see if it improves braking. Keep in mind that if you do lockup the brakes you want the front to lockup before the rear so that you don't negatively affect handling during braking.

 

When I had just the coils, mine was set in the middle.

When I used the spacers with the coils, it was set on the top.

When I broke it in Colorado, I drilled a hole and stuck a turn buckle down through it. Then I went to a wet parking lot, floored it, and then slammed on the brakes. I set it to right before the fronts locked up and it has been fine for 16k miles or so.

I also have 33's, so I am not sure how much braking stuff, blah blah is still effective. The truck stops and the brakes are fine. If it poops, then it is time for discs.
