Lowered my 15 all terrain with 2” drop shackles but it’s still 1 1/8” higher then the front. Anyone know where I can get a 1/2” block to replace the stock rear spring block.
I did Bell Tech shackles and removed the block in the rear (used the Bell Tech spacers for the U-bolt nuts) on my 17 Silverado LT and it's within 1/4" all the way around. The blocks are 1-1/4". U thought was gonna be lower in the back but it wasn't. Front and rear are a touch higher on the passenger side.

I ordered 1/2” spacers and have 2degree shims and belltech shocks coming. Don’t want it completely level for when I load it. I hate the sagging look which I still may get so I might look into helper bags.

This is the only pic I have till I get home. I did it myself but I’m also a mechanic. So all my tools are readily available. Like others have said the hardest part is folding the bed seam but an air hammer made it much easier. Other then that regular hand tools can get the job done.
That is looking good..I have a similar looking truck...I can see why you did it...You don't happen to be in the DFW Texas area and are interested in doing one...Did you have to adjust for Magride?

I live in the nyc area. Not sure how it would work for the mag ride suspension. I’m guessing you would have to adjust the sensor.

I have been told to either adjust the sensor or that the dealer can do a relearn of some type.

Did you see any loss of MPG...or any additional driveability/roughness issues added by lowering the back 2 inches?

I have been looking at a lowering shackle made by sulastic...it like an additional shock of some type take additional roughness off the leaf springs. Not sure if I am sold on it l. Probably go with standard good quality version though.

Ride quality seems the same. Only had them on about 2 weeks before I put the 22s on. I do have some shims coming to adjust pinion angle. Cause I will be lowering it with some shorter blocks to level it more.

Why did you buy shims

Good info and great looking truck...Thanks for sharing your experiences. Now I just need to find someone beat DFW Texas area with experience to install mine...Not going to pretend I don't have the right tool sets to do it my self and I don't want to mess anything up. Thanks again.

Some people complain about a vibration from pinion angle being off. The shims just realign the differential closer to stock position.

But why 2 degree and not 1?    You won't know until you drive tthe truck. It may work without them

From what I’m reading drop shackles with smaller blocks only need at most 2degrees. They are belltech so I’d rather order them and have them then not have them and need them. For the $20 they cost.

Thanks again for the info on shins with shackles...sounds like good plan b....when you can send a full side shit so I can see your current rake that would be awesome...I was playing in Photoshop with mine and feel this will be pretty close to my look.8032b91c672380f05b1535aa9d5e717e.jpg

Do you need shims if you are not changing out OEM blocks?

I have the Bell Tech 6401 kit, shackles and U-bolt nut spacers for removing the blocks and have no vibration or ride quality issues. No pinion angle shims.

You shouldn't need shims    the pinion angle gets better as the truck gets lower.  If you have a vibration i will doubt it's the pinion angle.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?

      The use of absolutes like "always" to describe gear selection, and giving free advice at a boat ramp sounds like a recipe for disaster. It's a boat ramp, not a farm, for starters.   IMO gear selection should depend on the obstacle. If low range is working and this is a slower speed, controlled ordeal, I'd keep using that.
