Repeating from that thread ---

Take a look at these from Sulastic.
Sulastic shackle replacement
We tried a set on one of our Dodge 3500 pickups we use as the farm truck. Empty it was a really rough ride. We decided to give the Sulastic shackles a try. The difference was like night and day. Now empty it rides like a soft sprung 1/2 ton pickup. No more rough ride when empty and it doesn't affect the load carrying when hauling weight.
What the Sulastic does is replace the rear shackle with a pivoting shackle that has a rubber tensioner. When empty the rubber tensioner flexes an inch or so. When you add weight to the truck the tensioner flexes until it hits the stop and then the regular springs are used like normal. We've run with some pretty good weight in the 3500 and the Sulastic works like designed where the stop engages and the regular springs are used. Remove the weight and it's a soft ride. It's a pretty simple design and one of those 'why didn't I think of that." It takes all of about 15 minutes to swap the shackles on each side. I've got a set for my F-350 Ford coming. I'll swap out the shackles on every heavy duty truck from now on. Best $400 alteration I've made.
There may be other companies making similar type shackles. The reason we tried the Sulastic is a neighbor had a set on his truck. I have no affiliation with Sulastic other than being a very satisfied customer and get nothing from anyone for recommending Sulastic.

I dying to order this product to get the DW to shut up as we travel about the ride quality.

It is very rough, yet I see it as its a 1 ton dually with an empty bed.
But if I can do some mods to get away from hearing her ***** & complain the whole trip, its worth trying this product out?

The price of what I'm about to order is $421.00.

Yes i saw your post in that other thread & I since called & I'm ready to charge my card!

But figured it might be worth posting a thread directly about this product to see if people hate it?

Or most love it?

I'm 90% likely to order it tomorrow!

I have it too. It definitely reduces harshness, by quite a bit. I wouldn't call the ride plush however. Mine are almost 10 years old and due to replacement. I plan on doing it again.

Thank you for the reply, So you have been happy with the product.

Glad to hear it.

I'm sure I'll notice a difference?
& will start with this & if need be afterwards swap out the rear coil over rear shocks.

I dont understand why you have coil over shocks to begin with. Add a extra $100 and get them gone as well.

Yeah, thats part of the Plan!

I bought the truck with those coilover'ed shocks already installed.

When you ditch the coilover shocks, get a good Monotube shock. Bilstein, KYB, Fox etc. Those will for sure make the ride softer, while providing better loaded control at the same time. But "shocks" (which are really dampers, and don't actually absorb shock....) won't help with the harshness that gets transmitted through leaf springs, and that's where the Sulastics come it. The act like an isolator for higher frequency vibrations, which we feel as harshness, or banging, when you hit an expansion joints cracks etc. And they also help reduce wheel hop on washboards (but the nature of a 800 pounds of unspring weight being a dually, it'll still happen, just not as easy).

Doing good monotube shocks in conjunction with Sulastics, your dually will ride at least as well as a stock 3/4-ton, if not better.

Thats my current plan, just figured I'd ask you people your thought on the product before spending the money.

I've been thinking an adjustable like the Rancho 9000 sounds like a decent way to go being adjustable.

Yet i do like Bilsteins.

Blanco,
If you install the Sulastic shackles it would be good to come back here with a review.
