The Carli Suspension Fabricated Leaf Spring Shackles CS-DSHACKLE-0313 are an excellent upgrade for your Dodge Ram 2500/3500, designed to replace the jarring ride caused by factory shackles. Much of the jarring ride of the leaf-sprung rear can be attributed to the factory vulcanized bushings in the leaf spring pack and shackle. The factory shackle is very strong but it is not conducive to providing a smooth ride. This is no surprise as these trucks were not made to ride well, they're made to tow. The factory leaf springs have a high-spring-rate and short-travel. RAM did not design a shackle that rides well and provides extended suspension travel. The vulcanized bushings are a press-fit which are utilized by many OEMs and it is adhered on both points of contact.
The OEM bushing material is adhered to both the shackle itself and the crush sleeve that the bolt goes through. The crush sleeve (silver sleeve that runs the length of the bushing) is very thick, which makes the bushing very thin. The bushing is only designed to move as much as it can deflect and when the deflection is minimal, your ride will suffer. Carli does everything they can to milk these trucks for the best ride. The vulcanized bushings may not seem like a big deal, until you consider there are 6 total bushings that fight suspension movement in the factory configuration - front leaf spring pivot, rear leaf spring pivot and shackle pivot.
Replacing the factory springs with Carli-spec Deavers will allow you to replace 4 of these (front and rear leaf-spring pivot) with free-moving, serviceable bushings; this shackle replaces the final 2. In contrast to the factory bushing, the Carli bushing assembly utilizes more bushing material and a thinner sleeve to prioritize ride damping. The Carli bushings are serviceable. Drop the rear end and grease them through the protected zerk fitting. The bushings are specially designed with channels for the grease to travel around for optimal grease migration and bushing life.
These bushing are serviceable, if you happen to wear out the Carli Shackle Bushings, you can simply buy new ones and swap them in, reusing the crush sleeve. The factory shackle requires replacement in its entirety when the bushings crack/rot. In short, the original shackle is beefy, but the press-fit OEM vulcanized bushings resist and bind during movement. This gives you a bad ride, no serviceability, and no rebuildability. The Carli shackle works wonders to free up the rear end of your truck (even fits factory leaf springs) while offering BOTH serviceability and rebuildability.

Perfect fit for our 2018 X5 35D
Perfect fit. Never replaced a filter in this car before and took me only 13 minutes. I timed it lol.
That includes taking some before and after pictures from the old and new filter.
What is worth mentioning is that the car was until now under the “fake maintenance” from BMW that comes with a new car and goes until 36.000 miles.
Up to this mileage there is no other service the. The oil changes (3) due. The first real checkup is at a higher mileage and not covered anymore.
Anyway , those filters where replaced before from a BMW dealership. When I compare the new filters and the filters I took out of the car they look the same.
I was expecting to find some BMW marks on the installed filter but perhaps they don’t put their name in it anymore??? Or it could be they also put “after market” parts in.
Anyway, BMW quoted me in all seriousness 700 dollar to replace those filters and the Inside filter
The inside filter is on its way and is 25 dollar. Together with those filters the parts came to 55 dollar and I guess a total of 30 minute of work.
Well done BMW, lol.
We all need to make a living buy that should be considered “robbery”
Anyway, if you thinking about replacing those filters then go for it.
It’s not complicated and all you need is a screw driver to get one plastic river out that you can push back in once you are done.
Those filters here from MANN are the real deal and fit perfectly and state that they are made in Germany. I have no reason not to believe it.

Excellent Product
It works really well. I used it on quarter tank and drove about 6 miles then filled up with top tier gas and my MPG went up by 3 miles on Highway and about 2 MPG city driving. At first there may be slight hesitation as it clears carbon. Then runs smooth as silk.

Quality product
Seeing as it passed the smog test without any issues, it seems this product worked exactly as intended.

So far so good
It seems to be working well, so far. The check engine light turned off and the my vehicle seems to be running well. Be sure to follow the instructions. A while back, I wasted some money on a different catalytic converter cleaner because I put the cleaner in on a full tank of gas. It's best to wait until you're at a half tank or less of gasoline before you put in your catalytic converter cleaner. Also, I drove around right after I put in the catalytic converter cleaner and before I filled up my tank again. A couple of days later, I went to the gas station and topped off my tank. Again, it seems to be running well for now.

Works ok for some stuff.
I tried this mainly to clean my cats. It sadly didn't work for that at all.
It did however work great as a basic fuel system cleaner. It smoothed out my idle and cleaned my O2 sensors they were a bit lazy before using this product now they switch fast like they are supposed too.
In terms of my recommendation I say use as a fuel system cleaner. Or if your cats aren't too clogged in my case I bought an old neglected used car that likely had that problem for years. So I don't think any pour in tank cleaner would work in my case.
However if your car just started having cat issues. This might work??
I think it's worth a try at least and isn't much more expensive than a basic fuel system cleaner so why not?
