While my truck was on the lift getting it's new straight 4" installed, I noticed that there is a valve on the framerail over the rear axle and a place for a linkage on the axle. The guy said it was a proportioning valve to modulate brake pressure to the rears depending on load. The linkage is missing and I was hoping someone (parts/service?) could help me get the right linkage. I'm sure it's important.
Also, love the new exhaust. Not too loud inside and should give the Smarty under my tree some breathing room. Thanks in advance.
