Might have to do a reverse level

[@jacobvandiver4043]

What ended up being the fix on this?

[@Southercalif]

I want to add this to my 15 megacab it just looks higher on the rear wonder if this works to level it on 35s

[@jessieschorr9034]

Where did you get the ladder bars

[@Rctreadaway]

You installed the shackles backwards although I doubt that would make it not drop as much but it could be binding some. Installed them on my 09 2500 4wd and it made a noticeable difference. Have a picture with the designated sides labeled if you want to see it. Just let me know where to send it. The offset is to get the shackle away from the hanger to keep it from interfering.

[@garrettbloomer]

Can you send it to me. I'm doing this tomorrow

[@bradleyrinker2378]

Can you send it to me as well? I know this is an old thread.

[@cm30256]

Rctreadaway Send me pics of install. [e-mail]

[@glnset-apart]

[e-mail] Can I get that picture?

[@pauldenbroeder8550]

got the same truck....curious if he found out after 4 years. And what brand he used......

[@allansafarik8428]

are there bump stops? sitting on them?

[@FrankA-973]

My buddy builds homemade moonshine stills and he tig welds copper all the time. You can tig weld a bead on the end of the pipes to hold the boot and clamp...strip the copper wire out of some Romex wire and then scotch bright the copper wire before you attempt to weld with it. It's a cool trick that allows you to weld copper..👍🏼

[@justinlienhoop4478]

Frank A That is a very helpful tip

[@TurbaTom]

Fig welding copper? I'm gonna have to look into that

[@weldorguy]

@@TurbaTom...yes, same thing as welding stainless, a scratch start too.....and sanded house wire as the filler ;)

[@derekschmucker1609]

I'd go ahead and connect your ladder bars back up and make sure that doesn't change anything. The other thing is if your shackles are dropped 2 inches that should theoretically drop the truck 1 inch( I think) because of the geometry of the leaf springs. If all else fails you can always pull a Greg A and start pulling leafs, right?

[@smithkid1996]

i agree with every part of this comment.

[@Thesongstaysthesame]

Derek Schmucker nailed it!

[@wilfreddompierre5620]

Yup agree Greg_A delete everything.

[@TurbaTom]

Yes, I think your right. The drop would be less then 2"

[@thebcd04]

When I do suspension work I wait till the suspension is loaded (wheels on the ground) before I tighten any bolts. Theory being if you tighten the bolts while the suspension is hanging loose it will put everything in a bind once loaded. Maybe all your bushings are bound up and won't let the suspension "relax" to final ride height. Try loosening all your bolts and see if you get your 2 inches.

[@TurbaTom]

Good idea, gonna try that

[@alpinesky8640]

I have an 04 qcsb building for 700hp so watching yours, optimal welding, and gregA's channel keeps me motivated and saving money for the next part. Also mad props for including the hunting footage. Im going out for elk opener here in Wyoming in the morning. Keep up the good work.

[@TurbaTom]

Thanks! Good luck hope you get a big one!

[@kevinlucasr20vet]

Place the truck on the ground and loosen the bolts and preload the traction bars and check measurements then tighten to 160lbs.

[@juanherrera2672]

I think Kevin Luca is right on Tom when I did my Carli rear leafs the destructions said torque shackle bolts with truck on ground that's supposed to put the truck at ride hight and not preload bushings or u can ruin the bushings if torqued in the air , kinda makes sense maybe that's what's up with those u put on

[@TurbaTom]

Gonna try loosening them up, thanks for the idea

[@OneNation_SpeakTruth]

Turba Tom did that work?

[@EssenceRare]

Turba Tom did it work?

[@weldorguy]

You can tig weld copper.....that would look great. Solder would be easy too.

[@alpinesky8640]

the problem with copper is it will transfer heat faster then steel. Not something you want transfering air your trying to cool down.

[@alpinesky8640]

I meant transfer ambient heat from the engine compartment.

[@TurbaTom]

That being said it should cool quicker also, not sure if the copper would hurt or help more

[@ricardodehoyos9312]

Yes keep it, it looks bad ass!!!

[@TurbaTom]

Thanks!

[@QuickStyleMotorsports]

ever get it figured out? keep upper and lower nuts loose until rear is lowered?

[@reddawng43x91]

Bro u torqued bolts before u let down the load of the truck ! 😂😂😂 loosen bolts top and bottom “after u jack it up “ then let down jack , now torque to 160 ft lbs. should be lowered now! Your welcome!

[@chenny9497]

Weird how it didn't drop it at all. Installed same ones few months ago (though on a 04) and it definitely lowered mine around 1.5 inches. I also don't have overloads.

[@TurbaTom]

Yeah it's confusing

[@jacobmonroe3918]

Tom you could sil-flos a ring on the end and sil-flos the 1/8th bends together which is much stronger than soldering ...love the look of the copper

[@TurbaTom]

Silver solder is much stronger, but not necessary for the amount of boost I see

[@chriswroten2204]

I think the copper is cool if you can get it to hold pressure.

[@TurbaTom]

It'll hold

[@tonyturner779]

Ever get this figured out? I'm about to install some on my 2wd 2012.

[@__Cperez]

is that a gates belt or a napa belt??

[@tylerlapadat3089]

I know this video is from a couple of months ago, but I just put these shackles on my truck. Had the same issue, well mine only dropped an inch. Did some investigating, turns out the shackle was hitting the hanger for it. Not sure if that could be your issue too, but it is something to look into.

[@brianbecker90]

I bought these same shackles for my 2004 Dodge also. Did not work for me, plus the shackle and spring bolt where hitting the hanger bracket..... and yes I did have them on the right way..... The guy at the store where I purchased said, sometimes you need to grind out your hanger bracket...... Im like No Fking way im doing that !!!

[@brianbecker90]

I bought the same shackles also.. Side of shackles hit hanger brackets ..WTF

[@heavyhans2296]

The copper inner cooler pipe is cool but you should cut the copper pipe down coming out of the inner cooler boot moving the first 45 closer and then put that difference between the two 45's to look more symmetrical

[@alpinesky8640]

I think you might need to loosen up the axel ubolts to reset them. With them still tight and you changeing the geometry of the leaf ride they might be holding tension and the new geometry is pulling the axel pinon down which in turn could raise the rear because the flat gussets that the leaf springs sit on would not be paralel to the frame causeing the rear end of the leaf to cantilever up. Im no expert just trying to brainstorm.

[@TurbaTom]

Possibly, gonna drive it some with no bars and see what happens

[@Justin-xo4ko]

I installed those exact same drop shackles on my '12. I did not notice a difference in drop and I have been driving on them for about 3 months now. In theory a 2" drop shackle should drop the truck 1" since your pivot point will be at the front of the spring and your axle sits in the middle of the spring..

[@TurbaTom]

After some driving I bet it drops a little

[@QuickStyleMotorsports]

end result here? loosen? didn't need to loosen anything? ride height still the same?

[@tylerroemer3009]

Good just like that

[@keytopic4578]

Well, you still have the other half of the spring in the same height as b4... so in theory you can get half of wht the rear drop was.Remove a few spacers or leaves too

[@JR-xi2ht]

I like the copper setup.

[@cummins0391]

Good video Tom. Keep up the good work!! Try losing the ubolts enough to take tension off rear end and see if that allows everything to adjust

[@jedodd64]

Looks cool

[@Matthewmiller28]

I'll assume your overload leaf is still installed? If so I'd take that out and leave 1block on the bottom and put the other 2 on top to take up the space for ubolt threads and go from there. Trial and error with doing this. Love watching your videos keep up the good work man

[@naildit3881]

pretty sure he took out the overload spring. I'm like tom, i don't get why it didn't drop at least an inch? it's all in the geometry and if you don't use those math skills every day, they kinda faid away.

[@TurbaTom]

Overload is out and two spacers are on top

[@gstubbz]

Copper looks sweet! I dig the idea!!

[@Nathankraml]

Keep the copper! That looks badass and it makes your truck stand out just a little bit more!

[@TurbaTom]

👍

[@wilfreddompierre5620]

Looks good to me.

[@chasecowler4307]

did you get new shocks to compensate the drop? if so what size and brand

[@TurbaTom]

I did, but probably didn't need too

[@mauc8193]

Can the 2019 2500 Longhorn be lowered? Complicated? Costly? Do it yourself ?

[@69bigsho]

And I laughed obviously didn't have the suspension loaded before he tightened everything

[@PoBoysDiesel]

definitely looks ""Steampunky "" cool but I think you will start turbulence which can cause air flow restriction It would be cool as all out if someone was to make a 1 piece peace pipe with all the bends in it how ever that can definitely get very expensive but for performance sake Id definitely recommend to just get a regular Stainless pipe made for it which will have less restrictions Every little bit counts in my book How ever I have to admit I appreciate your vision and imagination to create this makes for not only a fun video but also an interesting video Thanks for sharing Bud OH BTW about the shackles I wish I had an answer for ya but I honestly have no experience on suspension when it comes to lowering, lifting or leveling lol But I'm sure you'll have it all figured out in no time

[@TurbaTom]

I think the suspension just needs to go through its paces a few times and it will settle a bit

[@muscle24v93]

Its cool

[@ronriehle1337]

You got to hook the ladder bars back up !

[@profesional187pro4]

That looks cool 👍

[@aaronhoover6072]

Hacked up or not. If YOU like it, what else matters?

[@TurbaTom]

👍

[@Thesongstaysthesame]

Man if you think the copper looks cool And will hold the pressure, run it!!

[@TurbaTom]

👍

[@dwight072]

Use a 3rd gen s400 cover. I think it would look a lot better.

[@brianbecker90]

Shackes dont do a fucking thing................

[@brian_evins365]

Hey tom I had the same problem with my shackles it ended up being my helper springs

[@TurbaTom]

No helper/overloads here

[@d.a.r.123]

Keep the copper!

[@devodar2579]

hack for sure

[@lemoajammz]

Lol
