Dorman 924-070 Rear Leaf Spring Insert Compatible with Select Models, 4 Pack

These fit my 2022 F-350 with an exception of the bottom, bottom leaf where the hole had to be enlarged to fit the stud. They fit the top and middle leaf perfectly. My OEM ones were completely shot and these fit my super duty. We’ll see how long they last

I used these on a 2000 Dodge Ram 2500, they snapped right in. I'd say they are probably more for a 2.5" spring but they will work fine on a 3". My old ones were like paper. I had my pack apart to add a leaf.

Will work well.

My truck was driving me crazy squeaking. I figured out it was these shims for the rear leaf springs. The 08 tundra has four of these per leaf spring btw. I didn't know and only ordered four. I replaced the shims towards the end of the springs on three and one interior one and they are now squeak free. The others on the next spring were worn but not gone yet. You'll have to trim down the button on these to about 3/8 inch in order to get them in place. You can't separate the springs due to a spring retainer. Once I figured out how on one it took about 15 minutes each on the others. Hardest part is getting the springs open. I used a big chisel to open it and place the shim. Best 10 bucks I've spent for my sanity in a long time.

I used them on my 2010 Mitsubishi Triton Pickup.

Fit great on 99 Dakota

I own a 2000 F-350 Super Duty that I've had for 19 years. It used to be quiet but over the years I noticed that it got quite loud, especially when I hit bumps in the road. I had looked at other things on the truck trying to figure out what was causing it (the shocks, steering, etc.) but coundn't find it. Then I happened to notice that the leaf springs had holes at the end of them with nothing in them. After speaking to somebody that I know they told me what was in there. I found these and bought them for my truck about 6 months ago and what a difference. As soon as I put them on and took it for a drive I knew that I had found the cause. It sounds like a brand new truck and is so quiet. I cound't be happier, highly recommend.

They work but they are far more brittle than I expected.
