Sulastic rear spring reviews? Please post your results?

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

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 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!

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.
