I installed mine also.

Check to see where they put the spacers where the shackle mounts to the frame.
I found it odd that it calls for spacers on only one side of the shackle. (The side closest to the frame.)
Passenger side fell right into place, driver side needed to be persuaded when attaching to the leaf spring.

Haven't driven it yet, looks like I'm 1 1/4 higher , that may settle in though.

 

Had them on my 2007.5 LMM Duramax I recently sold. Smoothed out the ride a ton. I mean those trucks are already smooth, but it made the ride even better. Don't know that I will ever put them on my Dodge, but I would say they are well worth the coin to someone that is looking at them.

 

Test ride shows a vast improvement in ride & improved control.
Dont hesitate well worth the coin.

 

Interesting product. I appears that the entire weight of the rear of the truck is contained by rotational deflection of the rubber "spring", working in a scissors like motion. Kind of like scissors shocks in old MG's. I wonder how long they last?

I read through the instructions. It should not change the ride height by more than +/- 1/4". If your truck was raised by 1.5", maybe they're not installed correctly? Or maybe the posted instructions are wrong for your truck. Before spending money on more parts, I'd call them and see what they say.

 

The rear of my Duramax seemed to have raised up .5" after the install. Never did measure the height, but I got a pretty dang good eye been looking at a tape measure everyday for more than half of my life ha ha!

 

I would be REAL interested in buying these if they didn't raise the back end by 1.5-2". The back end is too high as it is; or the front end is too low. (2 wheel drive). Don

 

Yup, 2.0" is funny [not].

Glad to hear about ride improvement. You may have sold me.

 

Just installed a set, or should I say I had them installed. I have an advantage over the rest of you because I discovered that the factory is not that far from me, so arranged to go there and pick up a set. The price was cheaper than in the states. They offered to install them for an additional 150 pesos. Approx US$12. For that price, no way am I going to even attempt the job.
Was impressed with the installation. First they weighed every wheel and then took a bunch of measurements. Then they matched each unit to the truck. I asked why they did that and they told me that there are minor variations in each unit and for the HD trucks it is better to match them. They also showed me the manufacturing area. Every unit is load tested and the load marked on them.
Bottom line is that I was happy with the installation. My wife noticed the difference in the ride quality within 5 minutes and has approved this mod. The price so far is well worth it.
In about two weeks I am taking my fiver on a trip, so may have another report on my return.

 

Yea, there defiantly impressive.
Ill say it again money well spent

 

I looked for some feedback on these awhile ago and found nothing. I def am going to buy now. My girlfriend pointed out that her maxima rides a whole lot smoother than my truck, go figure.

 

Still very happy with this product. There is a huge improvement in the ride over small sharp bumps, such as the endless cobble stone roads in my area.
Just completed my first trip in the fiver with the Sulastics installed and even with that load can tell the difference.
I can definitely recommend this product.

 

let her know you could put her maxima in/on the bed of your truck and could still driver your truck lol.
glad to see this product has gotten such good reviews, need to look into these or the velvet ride shackles.

 

Had them for a few years now, yes they work.

Eddy,

Did they raise the back end of yours? Were they all you did to improve ride quality or did you find that more work was necessary?

 

how long of install was this, doesn't look to hard to install. looks great any other pics guys
