Thread: Load sensing proportioning valve/rear leaf spring add on

    Load sensing proportioning valve/rear leaf spring add on

    96 T100 x-cab 4wd, 3.4L.

    Okay so LSPV, how does one adjust it to compensate for a lift for the rear? How so you adjust it to compensate it if you do move it-some kinda pre-determined amount floating around (IE: 1" move for every inch of lift?)

    Anyone maybe got a pictorial showing how they moved it maybe?

    What im gonna do is possibly have my springs redone on the T100 by a shop and have them add just one leaf as I dont fancy the 3 leaf + 1 overload setup I have now and adding one to increase capacity a bit. Or I want to source a set of leafs from a wrecked 00-06 tundra as they use the same size leaf and put one of them in myself providing I can find the bushings.

    About the bushings-where would I get some, looked online and found nothing. A tundras will fit fine if anyone has an idea about where they sell them.

    Basically looking to replace the bushings, the springs I have now the bushings are rotted and leafs are probably worn after 200k.

    Adjust the LSPV 1" for every 1" of lift. Here's how you raise the axle-end of the LSPV (photo courtesy of 4crawler) - oone end bolts to the axle, LSPV bolts to the other end
