Cometic's MLS gaskets utilize multiple layers of stainless steel with advanced viton rubber coating, creating a gasket that recovers and reseals better than traditional composite gaskets. The embossed layers provide multiple sealing points while allowing the gasket to conform to imperfect sealing surfaces. This design makes Cometic gaskets ideal for high-performance builds, boosted applications, and engine rebuilds where reliability is critical.

Simple. Easy shopping

easy to use website ... hopefully the ship time is just as quick, as the site is simple

I found the best price any where for the Autolift 2.5 inch lift kit for my 04 Chevy Colorado. Autoplicity is an awesome place to shop for automobile parts and accessories.

Great price, and quick processing of my order. Will use again.

Unbelievably low prices and excellent customer service. theyre site charged me the wrong shipping, I'm thinking ok refund the difference. No they refunded me the full shipping amount. I'll definitely buy from these guys again, you can count on that. And English is their first language big plus!

Great Price! Fast Shipping!

First off, the price was excellent and they communicate every step of the sale. Shipping was immediate and arrived promptly with the complete order. One observation is the shipping calculator is flaky. I had to revise the order during checkout and noticed it seemed to give a different price each time. 6 cans of satin black $12 add 6 more of gloss, $15 change to 12 of the satin then $24 cancel order and purchase 12 satin then back to $15

I have had a very good experience with Autoplicity and will look for more parts here. I called Customer Service and they were very good and accurate with me. It was easy, they were very nice, immediate response, and great price.
