I ordered the CNS valve stem seal set for my 2004 Chevy Silverado, and they fit like a glove. The seals are high-quality and really helped with the oil leaks I've been dealing with. Great value for the price!

Not the best experience
I had high hopes for these seals, but unfortunately, one came damaged, and I had to contact customer service. They were helpful, but it set me back a few days on my project. The ones that were usable work fine, so it's a mixed bag.

Decent seals, but tricky installation
The valve stem seals from CNS are decent, but I found the installation process a bit tricky. The instructions weren't very clear, and I had to watch a few videos to get it right. They seem to be working fine now, though!

Great for my GMC but took a while to arrive
Happy with the CNS valve stem seals for my 2010 GMC Sierra. They stopped the oil consumption issue I was having, but I was kind of annoyed that shipping took longer than expected. Still worth it in the end!

Perfect fit for my Vortec engine
These CNS valve stem seals are an excellent fit for my 6.0L Vortec engine. I installed them with ease, and the quality seems solid. No more oil leaks! Would buy again if needed.
