Product Details

The MAHLE 3791MS-112 is a precision file-fit piston ring set designed for high-performance engine builds requiring exact ring gap specifications. This set is engineered for a 3.786-inch bore diameter with a +.005-inch oversize, providing optimal compression and oil control in custom engine applications.

Key Specifications:

  • Bore Size: 3.786 inches with +.005-inch oversize tolerance
  • Top Ring: 1.0mm metric thickness
  • Second Ring: 1.0mm metric thickness
  • Oil Ring: 2.0mm metric thickness
  • File-fit design allows custom end gap adjustment for precise fitment

MAHLE piston rings are manufactured to OE specifications using premium materials and advanced coating technologies. The file-fit feature enables engine builders to achieve the exact ring gap required for their specific application, accounting for bore finish, ring material expansion, and intended use. This ring set is ideal for performance rebuilds, racing applications, or any build where precise ring gap control is critical for maximizing compression seal and minimizing blow-by.

Autoplicity won my loyalty as a customer on two separate counts. Firstly, I am always researching the web for the lowest possible price on an item even while I am in the process of actually ordering it. I had filled in all of my info on their order page and had competed almost everything required concerning making this order. All that was left to do was my clicking of the final 'link' actually confirming the order. At this point I totally stopped and looked elsewhere on the web. A couple of hours later I came back to my computer and was surprised to see an email from Autoplicity asking me why I hadn't fully completed my order and offering me 3% off the purchase price if I would complete it. I immediately finished and submitted the order without hesitation. Secondly, a day or so after I had made the order, I received another email from Autoplicity offering me an additional $5.00 rebate if I wrote a review of my experience with them. Do you think they really want me as a customer? YOU BET!! I like companies that do business like this. They know how to make and keep loyal customers.
