    Hello All,
    I finally got around to installing my coachbuilder shackles and I had a few experiences I wanted to run past the experts on this forum!!! All in all, the job was fairly easy and is a nice upgrade to ride comfort.

    During the installation, I had a hard time getting the driver side leaf spring to line up with the shackle. It seemed like the spring pack was slightly twisted from the factor and pulled inward towards the spare tire. After a few good hits with the hammer and jacking up the truck, I was able to get the two aligned. The driver side shackle seemed to point in slightly more then the passenger side. Also, I choose to leave the bushings in because I plan to change out the rear shocks and add deaver pack in the near future so I avoided the trouble.

    Questions:
    1) did any of you experience similar alignment issues?
    2)does it look right in the picture
    3) did any of you have similar spacing between shackle and spare tire?
    4)short term, will OEM bushings be ok with shackles?

    Thanks for the help and input.

    Glad to see you had a chance to get your shackles installed :) The Tundra is setup a bit different than most other trucks, the frame rails after the rear portion of the cab are tapered and are not square with the leaf spring pivots. So unless your truck is sitting on a perfectly flat and level surface the rear axle will need a bit of help to get aligned after removing the factory shackles. Also keep in mind the factory shackles allow the axle to move just about where ever it wants, its sitting off center and sways to the left under acceleration. You'll also notice the winch that holds the spare tire up into place sits off the left and will need some help getting centered. All very common with the tundra.

    Please replace the factory rubber rear leaf spring eyelet bushings as soon as you're able to, They are biting into your Coachbuilder shackles and holding the lower pivots locked. I'll attach a pic.
    When you eventually swap out your leaf packs to the Deavers use a center punch and hammer to remove the new center sleeve and then tap the new poly bushings out and install into the Deavers. Our poly bushings are compatible with any aftermarket leaf pack. You'll notice a instant change in ride quality after upgrading to our poly bushings. Hope this helps. David

    Thanks David, I appreciate the quick response. I will put some time aside this weekend to replace bushings. Am I able to run the KING 2.5 front shocks and 2.5 rear shocks with these shackles? Forgive me for my ignorance however do I need the add-a-leaf pack if I have the shackles?

    I have the exact same question. I have King 2.5 inch rear shocks. Wondering if going with these shackles will cause them to max out. Anyone know?

    David, would the +2 shackles work with the 2.5 king shocks set at 3" and 2.5 king shock rears

    We've found with the factory leaf packs the amount of down travel isn't all that great. So with the factory rear shocks measuring 25.75" fully extended you're able to use a +1" / +1.25"/ +1.50" even though you're increasing ride height 1.75" with our +3" Coachbuilder shackles in the rear. Hope this helps.

    Yes, this works excellent.

    Does this mean even with the +3 shackles the factory rear shocks are ok? Just checking cause I assumed I needed a new rear shock that can go another 2 inches.

    Also do the rear bushings work with all shackles? Or are the specific to the ones you build?

    Thanks!

    Our +3"s will def "work" with your OE rear shocks but always recommend matching the rear shocks with what ever you're using up front. Chances are the new rears will be offered in a +1" length and will work with any of our shackles. Our Poly bushing kit is specific to our shackles and are both machined to pivot together. We have had some guys use our poly bushing kit with their factory shackles though. if you need a hand with anything please feel free to let me know. 801-635-4872

    Thanks so much! I may call when I get closer. I am thinking to do a nice 3/2 lift with Bilstein 6112’s in the front and using your shims to get a solid 3”.

    Then for the rear your +3 shackles. Wasn’t sure at first if a 5100 “0-1” lift shock was ok. Or if I needed to go to a 5160 that was good for “0-2” lift considering factory leaf pack down travel.

    Glad to help :) The 3"/2" system is Awesome!!! Either 5100's or 5160s would work with your 6112's up front. Depending on your application the 5100s may be just fine but if you're running your truck hard and need the larger diameter and oil capacity the 5160s would be the shock to use. Excited to see this come together for you. We recently set up one of the TRD Racing Pit trucks with this exact system. Truck looks level but still has a slight rear rake and is very capable on or off road :bowdown:

    Thanks again. Yes this was the idea I’m saving up for. It won’t be used for heavy off-road so maybe the 5100’s are good.

    I felt like anything past 3” upfront probably needs drop brackets/spindles and a bunch more money. Lol

    My thought was a nice 3/2 and possibly the new icon rebound 17” wheels. Little more side wall for comfort and cheaper tires in the long run. :)

    @Coachbuilder1 Do you have a "how to video" on bushing installation? Do you mind providing one

    https://www.youtube.com/watch?v=9DMvzjVw1VM There a quite a few out there some much better than others but for the most part you can see how helpful a ball joint press tool is. Advanced auto parts or Auto Zone will let you borrow a kit, I normally don't use the bolt in the center like this video shows but def can. Let me know if you you need any other help. 801-635-4872
