COACHBUILDER SHACKLE HELP!

So I purchased the 3+ Shackles from coachbuilder and getting ready to install but running into problems. I currently have a 6” pro comp suspension with the rear blocks and i want to level out my truck so i want to lift the rear up more i need to know if anybody has added lift shackles to a already lifted with blocks truck I removed the old shackles but the leaf has so much tension on the frame of the truck even lifting it from the tow hitch doesnt budge a bit what am i doing wrong?

 

Did you remove the lower shock bolt so that the leafs can droop further?

 

No didnt think about that will that help alot? Ima start doing it right now

 

Yes, the shocks become a limiter for the droop.

 

Has the be the bottoms nuts of the shocks cant be the top? Whats the difference

 

Bottoms easier, both to remove and attach. Do the bottom ones.

 

About to try that right now lets see if it budges a bit thats bro

 

Just watch your break lines as you lower the axle. To the left of the diff (looking from the back).

 

Well im not planning on taking off my wheels so i want to lift the frame instead of dropping the axle?

 

The lines mount to the axle and are attached overhead to the bed/frame so they will get some tension on them as the frame moves upward. Should be fine, just keep and eye on them is all. Good luck, hope that gets it.

 

So i just finished but guess what now my shocks dont reach the bottom mount anymore and i have the fox shocks for 4-7” rear lift what gives

 

Getting ready to head out, but they dont reach, even with the truck on the ground with nothing lifting or supporting it?

 

Nope bro i already took of the floor jack and everything

 

I am in a inclined drive way maybe if i turn it around where the rear is towards the street that way the weight goes towards the rear?

 

Try placing the jack under the pumpkin/diff and lifting, the leafs will flex some and hopefully allow you to remount it. The shackles shouldnt lift it that much to make that big of a difference as that looks closer to 3". Could also see if the shock is maxed or not by trying to pull down on the lower mount/eyelet.

If either dont work the shock is possibly not long enough. Their gas charged though so should fully extend when released, but might still have some slack.

 

If that doesnt work you can try putting a bottle jack on top of the leafs and seeing if it can help extend the leaf downward.

Edit: you would do this after removing one shackle both to release the rear leaf and the attaching the lower shock mount. Using the bottle jack would then help to realign the bolt hole of the shackle by moving the leaf down further.

All should be done with the rear in the air and leaf drooped.

 

I tried lifting the axle but the whole rear lifts with it lol thinking about emailing coachbuilder and asking what to do in this circumstances i saw that theres lower mount extensions but not sure if thats the best way to go for now

 

Looks like you will need new shocks to run a +3 shackle on a 6in lift.
6+3=9 in lift. You may not be at the full 9in of lift but your shocks are at full extension and look about 2in short.

 

+3 Shackle is a 1.75" lift

 

Did you torque the shackle bolts up in the air? That’s supposed to be done on the ground, so that could bind them and make it look like you have more lift than you should. But you’re also running 7.75” of lift if you have a 6” kit with +3 shackles (1.75” lift). You probably maxed out the shocks.

 

Thanks for the correction.
The rear shocks are still charged with nitrogen and go to full extension unconstrained.
They still look too short

 

Its the +3 shackle i believe it lifts it up 1.75 only i wish it was actually 3” lol

 

@TRDFerguson You might be right I did torque the shackle bolts while the jack was still on the hitch im not sure how that changes anything tho but you never know im thinking of buying some mount extensions that bolt up to the bottom mount on the axle and extend it to the shock alos might have to buy a thread extension for the top also ‍♂️

 

The do look a little straight up and down, mine have a slight angle to them. If you search for images of them you will see a lot of them angle toward the back of the truck.

 

Try moving the truck to let the leafs settle.
doesn't hurt to jump on the rear bumper and cycle it a little either.

 

Yeah I moved it and it looks like the shocks got a bit lower for sure but just not there yet

 

Might just go get me a bed full of mulch and see if with the weight the shocks align back jk

 

Have you loosened the shackle bolts yet to see if you get some articulation back there? It does look like they’re much more up and down than shackles should be.

 

Should i loosen up the bottom shackle or top and bottom?

 

Probably need both to be loose, just hand tight. Then once you get the shocks attached, torque them to spec on the ground
