This precision-manufactured gasket features Cometic's proven MLS construction with a compressed thickness of .027 inches, providing superior sealing performance for high-performance and racing applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum durability and reusability

  • 4.375-inch bore diameter designed for Chevrolet Mark IV Big Block engines
  • Embossed stainless steel layers with Viton rubber sealing beads

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

I was very pleased with my transaction with Autoplicity. My order was shipped the next day and received the following day. The pricing was also the best I could find. I would definitely buy from them again and recommend them to others.

Very nice process!

Lowest prices, free and fast shipping, excellent product.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.
