This timing cover gasket set is a good quality set. It does not leak. It fits perfectly and is easy to install.

Great price. Looks like OE. Time will tell how it holds up but I'm confident so far.

I haven’t fully installed it yet, but it looks identical in materials and fitment to the original Ls3 gasket than came off the engine. The rubber is supple and I think it will seal well.

Excellent value here. Comes in a no-frills cardboard sleeve. Materials and construction are good quality. Stop that massive oil slick coating the bottom of my 5.3L. Highly recommend.
