SULASTIC LEAF SPRING SHACKLES
Any fellow members here running the Sulastic Leaf Spring Shackles?
If Yes, did they truly and noticeably improve your unloaded ride quality at the rear?
Sulastic tells me that their leaf spring shackles can improve my rear ride quality by as much as 50% (not sure how they come to that metric).

Tons of threads on these on the forum if you search. All mostly positive claiming improvement. I'm installing mine this weekend and will let you know, however I will not be using the scientific method and will either be, yeah feels like it rides better or meh no real difference.
I can tell you this, I watched for about 6 months on ebay for a coupon and bought what I believe was direct from them and paid 359 out the door. Best price I could find at the time.

I installed them on my previous truck and will install them on my new truck.
I would not say they were a 50% improvement....that's a pretty big wow factor and if the wife didn't notice a difference...and mine did not. he metric more in the 5% to 10% realm.
the sulastics will take away the bang-hop folks complain about...aka..wheel hop.
is worth the 400 plus bucks and the labor...it depends what else you have done to the truck and what your goals are. I had summon springs, fox 2.5 shocks, centronics wheel balancers, then I added the sulastics. every add on does something different.

Just has Sulastic Spring Shackles (SA-06F) installed yesterday on my '19 F250 6.7L FX4 CCSB and amazed at the difference in ride quality. In fact, I'm of the opinion that the small bump compliance is now better in the rear (with an empty bed) than it is on the front where all the weight is (Bilstien 5100's all around) and the truck feels far more "planted" at the rear, with no more hop/skip and jump! The Alignment Guru I use was equally if not more impressed than myself with the difference between the before and after install road test.
Yeah, some say $400 bucks for the Sulastic shackles is a lot to pay but if your seeking to improve rear axle ride quality without sacrificing payload then the Sulastic shackles are something worth considering vs. add-a-leafs, etc.
