Sulastic Shock Absorber Shackles for REAR Leaf Spring Suspension model SA-06F - Compatible with Ford 2017-2023 F-250

They do make a difference, i installed them on my 2022 f250 6.7 it rides a little bit better like an f-150. Its worth the $500 especially if your trying to multitask while driving and you hit a few pot holes and your drink goes flying out the cup holder and everything on your center console goes flying. These ease that initial blam by about 35-45%. I think i did notice having a outlander 700 in the bed before and after it will sit an inch lower than before with a 7,000 trailer on the back. Theres no down sides to this product you can only improve with it. Installing them was pretty easy too, the 2nd side always goes quicker. Also if your looking to make the truck ride smoother, only put OEM shock absorbers back on, all the after market ones suck and blow out quickly. Then they just want to send you a replacement product that fails in less than a month, not an actual refund. Then air the tires down to 45-55 psi, i hope this information finds you other super duty owners, it cost me alot of money to learn hopefully yall dont have to do the same either.

As advertised! Ive owned a several 3/4 ton trucks over the years, all makes. They all rode rough. After several complaints from my better half about the ride on my latest 2021 Ford F250, I hopped on the google bus and learned about sulastic shackles. Price was reasonable so I gave them a shot. Install was a breeze because I paid a shop, because 98* in Texas. Immediate butt testing determined that the shackles knocked down 85% of the jarring, compressed disc inducing, coffee spilling bumps in the road when the truck is unloaded. Don’t get it wrong, it still rides like a truck. But more like a cushy half ton than a dump truck. Kicking myself for not discovering sooner!

Added to my 2023 F250 and the ride does feel smoother especially when the truck is empty or not towing a trailer. The ride height was not affected and it is a relatively easy install. The only down side is my bed scales in the truck are no longer accurate but I never used that feature anyway so it is not a deal breaker for me.

Installed these and it helps with keeping my truck from bouncing quite a bit. Will be using them on all my 3/4 ton and above trucks.

Worked good for about two weeks now seems worse out and they function at probably 25% . If they wasn’t such a pain In the butt to take off I would have .

I purchased these from my 2020 Ford F-250. After buying the truck I was thinking about selling in with in the first month to go back to the F150. The factory ride felt like I was riding in a Yellow school bus. I love the power of the F 250 diesel for all the towing I do. I was very close to giving up the truck from all the kidney punches felt over every bump. So I searched and search for solutions to the hard ride from factory. Everyone seems to have their own opinion on what to do. From shocks to full lift kits. I am so happy with spending $500 for these Shackles and took only an hour to install (very easy thing to install). 4 bolts that easily slide in to place by use of a floor jack is pretty much it! Then went for the road test. ALL I COULD KEEP SAYING TO MY FRIEND IN THE PASSENGER SEAT WAS,” THIS IS UNBELIEVABLE, THE RIDE IS SO IMPROVED”! He couldn’t believe it either. I let him drive it for about 5 miles back and he was so impressed. I know, like I mentioned already, people have their own opinions and searching for answers to soften your ride. Well I’m letting you know here if you are just looking to soft the ride and not do crazy suspension upgrades, this is the fix! I CAN PROMISE YOU THAT SULASTIC SHACKLES WILL AMAZE YOU!

Just installed on my 2019 F 450 and love it so far. On smooth roads the tire bounce is gone. I drove over the same bridge I go over everyday for the test. This bridge would snap your neck back if not aware of it. Big difference to say the least. You still fell it but not as sharp / jolting. Took it on the interstate at 70mph and through our construction zone all kinds of road conditions much better. All cast no welds, we'll see on rubber performance. It works.

Meh! Placebo effect? Finally got around to installing these “shackle replacements “ and I’m not really seeing much improvement that makes it worth it on my 2025 2500 Silverado. I’m maybe just a worry warrior but based off of how these sit in place vs stock shackle makes me feel like it has a failing point. Too much of a pain to remove and return.
