I got these for a 2006 Silverado 1500. The install was super easy, and my truck looks amazing and leveled, but heres a few tips thatll help: The night before, and morning of, I sprayed rust penetrant on both bolts holding the old shackles on, then drove it around. This will make hardware removal a breeze. I put the jack stands under the rear of the cab, on their lowest height (harbor freight 6 ton). I used a bottle jack under the rear differential in order to relieve side load on the bolts. Once the nuts were off, and with zero side load, the bolts are easy to slide off. I took the old bolts and cleaned them with degreaser, and put a light coat of grease on them for the install. Clean the inside of the bracket where the bottom of the shackle will bolt into. Usually theres a lot of grime there (like 1/16" thick), and wiping it off will help the new shackles slide right in. Also spray WD40 on the bracket where you just cleaned. Bolt the shackle to the leaf spring first. You can use the bottle jack under the differential to lift it up all the way, to slide the bolts between the frame rail and the bed for the most clearance. Then, align the shackle where it sits in the lower bracket, and slowly release pressure from the bottle jack. They'll slide right in. Overall, the process took me maybe 3 hours with hand tools and minimal skill. Easily the best $40 upgrade I've done to my truck Read more
I installed these shackles on my 2014 GMC Sierra. Great quality and easy to install. Basically just two bolts to remove from the old shackle. You will use the 2 stock bolts to secure the new lowered shackle in its place. You will have to remove the tow hitch so you have room to remove the bottom shackle bolt and will also have to loosen the bolts connecting the bed to the frame in order to raise the top shackle bolt enough to remove it over the truck's frame. I was able to find an install video on YouTube that helped. They lowered the back of my truck exactly 2 inches and I am very happy with the look. I haven't noticed any changes in ride quality from stock. Highly recommend these! The pics are the measurements from the ground to the top of the wheel well. Read more
Great buy, the height in right on the money, I would recommend. Read more
So, the shackles are a real pain to install on a newer Chevy, though it's not the shackles fault. You've got to basically unbolt the bed of the truck and lift up on it to be able to get the top bolt out and back in. No star deducted for that, gave 4 stars because it didn't fully level the truck (still 1/2-3/4 inch high in the back)... plan to remove the factory rear blocks (1.25") but that'll put me 1/2-3/4" low in the back. Wish they'd make this as a 1.5 / 2.5 shackle so you didn't fall between too high and too low (with the blocks removed) Read more
Not much to say. These work, ride quality isn't compromised, just an easy 2" drop. One thing to keep in mind, you have to unbolt the rear 4 bolts of your bed to get everything to clear. It sounds awful, but it's not, so long as you know it's gonna happen. Pull your hitch and spare tire too for extra space. Read more
I've used both Bell Tech and McGaughys lowering shackles before. My own opinion is that McGaughys are of better overall quality. Lowering the rear of the truck using these shackles certainly improves the overall appearance and doesn't adversely affect the load rating. It also gets some of the weight of the front of the truck and onto the rear which helps to balance out tire wear and improve handling. The adjustability is nice feature if you're trying to correct the "Chevy lean" that some of these trucks are known for. Read more
