* For General Motor vehicles with factory radiators only.* Fits various GM vehicles with small block engines.* Durable Urethane.* Four isolators included.
I was excited to use these radiator isolators, but they came with a dent and didn’t fit quite right on my setup. The material feels good, but I can't use them now. Disappointed with the shipping quality.

Solid choice for engine protection
I installed these Prothane urethane radiator isolators on my small block Chevy, and they work great! The red color adds a nice touch under the hood, and they seem to absorb vibrations really well. Definitely feel like they’ll last longer than the stock ones.

Better than rubber, but could use improvement
I switched to these urethane isolators for my GM engine and noticed reduced engine noise, which is nice. They’re pretty sturdy, but the installation instructions weren’t super clear. I had to figure out a couple of things on my own.

Good product, but took a while to arrive
These isolators from Prothane are decent. They fit well and look pretty cool in red. However, the shipping took longer than I expected, which was a bit frustrating. Still, they do the job once installed!

Highly effective for my radiator setup
These Prothane radiator isolators really did a great job for my small block. I love the red color and they fit perfectly. The vibration dampening is noticeable, and they look awesome too! Definitely recommend if you're looking to upgrade.
