Review: Good deal, quality material - Got these from desertcart warehouse, as described. Not much to them but they are made of a dense material which I don't expect will crumble any time soon. I prefer rubber for body mounts but these should be great for a radiator.
Review: works great - they work

### ⭐⭐⭐⭐⭐ Good deal, quality material
*by J***H on June 23, 2020*

Got these from Amazon warehouse, as described. Not much to them but they are made of a dense material which I don't expect will crumble any time soon. I prefer rubber for body mounts but these should be great for a radiator.

### ⭐⭐⭐⭐⭐ works great
*by C***S on December 21, 2025*

they work

### ⭐⭐⭐⭐ Great replacement for your worn out rubbers
*by R***E on August 7, 2020*

First off let me confirm these fit my 1976 Chevy C10, with a caveat. I had to trim two down to fit the top rad mount . Other than the two that needed trimming to fit (used hacksaw to trim excess), these fit everywhere else perfectly, and the old rubber isolators the truck had are so worn out they allowed my aluminum radiator to hit and rub the rad support. These solved all my rad mounting issues. They hold the rad so much tighter, and put it exactly where it needs to be. If you think prothane is just for suspension, think again, love these, only way they could have gotten 5 stars was if i didnt have to trim the top 2
