Did the lowering shackles and it's still 3/4" higher in the back. A Forum member suggested that I replace the stock spring block, which is 2.25" thick, with one that's 1/2" thick. That should take care of that. I ordered them yesterday so maybe I can get them on this week. It sucks to be anal:). Tapatalk via iPhone 5s

 

The factory is actually 1.257" thick, another member posted a picture of one with a caliper to measure its thickness :D

How hard are the drop shackles to install? Can it be done in a grage by one person with normal tools? What's the most difficult part?

Thanks.

I think the fuel tank needs to be dropped so the left can be pulled

Not true. Takes about an hour. Receiver hitch will need to come down to get bolt out on one side. Should take about 1-2 hours depending on how fast you work.

Post a good side pic and f/r measurements if you get yours done before me lol

 

And sorry man didn't read all the way. Wasn't meaning to come off as rude.

I got tired of jacking around with waiting for somebody to do my lowering blocks so I just did it myself today. Turned out GREAT. I'm attaching some pics for you below. The only thing I forgot to get for you was the front measurement but after looking at the pics you'll see it's PERFECT!! I'll be looking for pics of yours tomorrow!!

 

 

This is the rear measurement.

No. I got 2" shackles too but it was still about ¾" too high in the rear so I removed the factory block that was approximately 1¼" and replaced it with a ½" block to make up the difference. Now it's PERFECT!!!

No. I also have the 2" shackles but it was still about ¾" too high in the rear. Thanks to brentadams646 I found out about the blocks. I replaced the factory 1¼" with a ½" block and that made up the difference. Now it's perfect!

In that last pic, is the rear like super close to the bump stop???

I didn't notice it being too close. Maybe it's just an optical illusion. I drove it quite a bit after I got done and it rode just like it always did. We have "speed humps" in our neighborhood and didn't notice a bit of difference in negotiating those stupid things. It rides like it did the day I picked it up from the dealer. I just couldn't be happier. Thanks Brent!!!!!

Dude it looks perfect!!!!!! Mine goes to the shop tomorrow at 8am. Glad everything worked out just right! Take a hack saw with a blade for cutting steel (fine tooth) and saw off the bump stop at the first indention from the bottom. I've done it before.

 

And you're welcome man!

I need to cut my bump stops, plan on doing it once it warms up. Only bad about leveling the rear is it moves the shock up 2" into the valving range. I have found on hard dips the truck will blow thru the valving pretty quick and allow the rear end to bottom out and hit the bumps stops. I am waiting on Rancho to get the OEM specs for the shocks and see if they make a shock that will work with a leveled setup.

    • Uh yes, that's the name of the package. It doesn't quite bring it up to 1 ton specs unfortunately and imagine they have to do that for a numbers reason rather than a physical one.    Am I correct though that the Max Trailer Package and therefore the 12" rear is only available on the Duramax and not on any of the L8T 3/4 ton trucks ( and that the same 11.5 rear axle center section is used on the 3/4, 1 ton SRW and even 1 ton dually gas version ) ?   I'd also be curious to know if the wheel bearings are the same on a SRW configuration between an 11.5 vs the 12" diff as I assume parts would show that up but may not explain what the difference is if indeed there was a physical difference. 
    • Why is gas up? Same reason the deficit is now $40 Trillion.
    • Mobil up another dime this am , $3.89, others will probably go up later. Any ideas on the reason for the increase other than greed? I've been working 14 hour days and haven't caught the news in a few days.
    • AMSOIL SS is about prevention and it is very good at it's job. I've never seen it claim to be a cleaner however like Valvoline R&P. Almost any oil that has some Ester or Alkylated Naphthalene in sufficient quantity will do a good job at keeping the rings functional.     I see the market splint among these types in two groups; those that use the same tech in every weight grade and those that reserve the tech for the EPA (EPA) friendly grades. Mobil 1 for example keeps the Advanced Clean chemistry out of the SAE 40 and up weights. Other like HPL (top shelf group and No-VII), Red Line HP, TORCO, MPT30K use the tech in all grades. Just not something the Wally World oils are into.
