Mastersntx Posted December 8, 2020 Share Posted December 8, 2020 Ok, just picked up a 1988 4x4 Short Box. The D44 has this lovely item on it and I searched, but cannot seem to find any info on that it is. Any ideas? Link to comment Share on other sites More sharing options...
eaglescout526 Posted December 8, 2020 Share Posted December 8, 2020 That’s what we famously call the height sensing valve. It is for the rear brakes. It’s so that way when you have a heavy load, you’ll get better braking in the rear than the front. It doesn’t have anything to do with the axle other than the rod connected to it to help move the height valve up and down. Link to comment Share on other sites More sharing options...
Jesse J Posted December 8, 2020 Share Posted December 8, 2020 thanks for asking this I was wondering the same thing but was too scared to ask. Is it good, bad, meh? Also go add it to the registry one of these kind folks will get you a build sheet Link to comment Share on other sites More sharing options...
eaglescout526 Posted December 8, 2020 Share Posted December 8, 2020 Well it’s a good part to have. Most bypass it but it works as it should if it still works. It can be tested by disconnecting the rod and zip tying it upward for maximum “load” to per say. If you stop faster and quicker, it works. If you stop the same then something is wrong with it and it’s not giving more braking power. Link to comment Share on other sites More sharing options...

HOrnbrod did a write up on an adjustable one that won’t have the plastic clips brake in the future. Link to comment Share on other sites More sharing options...
