Pictures and specs on lifted duramax 1500 silverado's

It's a 3 inch lift, since I have the heaviest front I'm not too concerned. And since they are threaded bodys, if it's too tall I can always lower it.

When Filthy saws 2.5 they mean 2.5 of actual lift, not a "2.5 kit". With Kings the rod end is exchangeable as well. So if I need too I can get the shortest one.

I have a six inch lift with 2500 and although I love the truck it definitely completely changed it compared to a stock one. since I do so many miles I'm trying to stay as close to stock as possible.

then if I find out, oh actually no I do need an additional 3 in of lift, superlift is going to launch their Black diamond King edition which will be an available upgrade with parts that you can add if you already have the king kit.

Finally found someone who isn't going to sell me what I want but what will work.He's done over 50 new gm and chevy lifts .....if your going mild it's 2.5 or less any higher than that and you better start putting some drop cross members in ,as the angles on the cv and drive shafts are just to steep for long term durability. In his words you can do 3 or 4 inch spacer or strut lifts but don't expect it to hold up off road, basically your just building a pavement queen.His recommendation ... use the bilstein 5100 lift stuts and a set of 33-34 inch tires and should be good.I wasn't looking to put 35's on and lose 5mpg or more but to get better travel and ride than the crappy rancho shocks they try and pass of as "upgrade" shocks and it's just about a grand less then the trail boss kit..Not to knock anybodies choice (especially topgear) because we all see the picture a little bit different.The reason for this choice is the other upper end shocks are great but if your not doing aggressive off roading at higher speeds your you never going to appreciate the benefits of these shocks and they do not hold up as well in cold,salty grimy conditions not only that but a $2600.00 package US is 4 grand + in Canada. My off road speed is more in the 10-20mph speed not the 60+ of the desert racers. Thanks topgear for the help in getting to the decision.

The rear isn't coils, it's 2.5inch piggy back shocks with adjusters. Only rams have coils... So far

Topgear, May be a silly question but you are sure the rear 2.5 piggybacks from king will fit on our truck. I ask because I’ve only see pictures of our silverados with the remote reservoirs mounted in wheel well, and the shocks are massive for two piggy backed. I should be ordering the kings soon and would much prefer piggyback in the rear. Thanks!

did you know originally they were actually supposed to have rancho monotube on their Z71 and X31 package and it was changed last minute to a twin tube. They kept the monotube on the trail boss though.

No problem, yeah I'm building a "mini raptor". my benchmark is gen 1 raptor, which is a truck I'm extremely familiar with, even though I never owned it.

Although I do love my bilsteins on my 2500HD, you do really have to get speed in them and get the suspension moving to feel their benefits if you're below that threshold it does ride pretty rough (lots of unsprung weight from the 35s and their load range E2).

I do a lot of dirt / gravel / chip seal / broken asphalt. I also bought the long wheelbase for better travel on long highway journeys so a linear rate is actually going to work better for me as I'm not super interested in the actual on-road handling (with in reason). I don't mind my trucks to move around as they drive down the road as long as it's controlled and it makes sense.

the stock X31 suspension I will say having driven older Chevy z71s actually does work much better off-road, the problem is is you have to get it up to about 30 to 40 miles an hour and then the shocks run out of control at around 45 to 50 depending on how rough the dirt road is. Below 30 or so it's like riding on solid suspension, no movement.

This was the biggest reason I didn't choose bilsteins for this build, I didn't want digressive shocks, they're amazing on the road but over sharp sudden impacts they suck. Couple that with a spring rate that's likely very close to factory and the fact that when I purchased my kit they only had a 2.0 not a 2.5 available and they were off the table for me.

I really really wanted Fox's DSC kit but originally they only had the kit available for the front. Then I saw that they updated their product book to include ones for the rear but they explicitly state that they do not fit Trail Boss and that you cannot apply any lift whatsoever.

I was looking for a touch more travel in the rear. That basically left Icon and Kings. Icon is a digressive shock however in all fairness Icon does test the crap out of their products, offer free revalving, and they have some of the best customer service of any of the shock manufacturers.

However I knew I wanted remote reservoirs for those long 400 mile journeys on dirt and I knew I wanted adjusters so that way I could firm up the rear if I'm running a lot of tongue weight when I'm towing on the road. When I priced it out for Icon I could not justify the price increase over the Kings.

Stumbling across super lift that also included upper control arms and the rear block was just icing on the cake. At a price that was less than Camburg or Filthy could do. Add in a powertrain warranty and I knew what I was buying.

Technically the rear reservoir IS remote mounted inside of the fender well (at least from what I've seen.). So it isn't really a piggyback, as that would be solidly mounted to the main assembly.

I won't have access to the actual install paperwork that's inside of the kit for about another 2 weeks as I had it shipped down south.

But it appears to mount the same way that my front bilsteins did on my 2500 which is with mounts that you bolt to the frame and then you use the hose clamps to secure the reservoirs.

I'm actually pretty lucky we don't salt the roads up here so the actual corrosion isn't going to be massive though I am probably going to go ahead and clear bra the main assembly just to kind of protect them.

Here is the Black diamond kit that is complete but hasn't been launched due to covid-19.

I don't really care about all the fancy stuff, I just paid really close attention to the ride and you can see the dampening is incredibly well controlled even on a 6-in lift.
