01 Lb7 ext cab sb, took the harshness out of my ride and smoothed out a bit bit wont make it like a cadillac if thats what your expecting, semi worth it, it does make your truck squat more than it would normally under trailer load or heavy bed load but worth it when empty.
Just had DMAX Store replace the stock shackles on my 2002 2500HD, 6" lift, 35" tires with the Sulastic Shackle Kit. Although I was a little unsure if the ride was going to improve enough to offset the cost. I went for it anyway, my truck has 160K miles and is a crew cab LB7 and I had a rattle in the back of the truck in the suspension for some time and the last thing left was worn rear shackle bushings. After a week of testing the ride has smoothed out and improved considerably and has the same characteristic as stock when towing as well. I would recommend this shackle upgrade to anyone wanting to get an even smoother ride out of there already great GM Truck.
