Product Details

The Cometic C5720-120 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for the Buick 3800 Series II and Series III V6 engines. This gasket features a .120" (120 thousandths) compressed thickness and a 3.840" bore diameter, making it ideal for left-hand side (LHS) cylinder head applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .120" compressed gasket thickness for optimal compression ratio tuning
  • 3.840" bore diameter precisely matched to Buick 3800 engine specifications
  • Engineered for left-hand side (driver side) cylinder head installation
  • Compatible with both Series II and Series III versions of the GM 3800 V6
  • Premium materials resist combustion chamber temperatures and pressures

Cometic MLS head gaskets utilize multiple layers of stainless steel with elastomeric coatings to provide exceptional sealing under high cylinder pressures. The layered design allows for minor imperfections in sealing surfaces while maintaining superior combustion sealing. This gasket is an excellent choice for stock rebuilds, performance upgrades, or engines with mild to moderate boost applications.

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.

Easy process so far.

very prompt service,items were in stock and shipped next day,salesman was helpful and friendly.Will place in favorites and do buisness with again.

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.
