Product Details

The MAHLE 4005MS-112 is a high-quality file-fit piston ring set engineered for precision engine builds requiring custom ring end gap adjustment. Designed for a 4.005-inch bore diameter (4.000" +.005" oversize), this three-piece ring set delivers reliable compression sealing and oil control in performance and racing applications.

Key Specifications:

  • Bore Size: 4.005 inches (4.000" + .005" oversize)
  • Top Ring Width: 1.0mm
  • Second Ring Width: 1.0mm
  • Oil Ring Width: 2.0mm
  • File-fit design allows custom end gap fitting for optimal seal
  • Precision-manufactured to MAHLE OE quality standards

File-fit rings arrive with unfinished end gaps, enabling engine builders to hand-file each ring to achieve precise end gap specifications matched to the specific cylinder bore and application requirements. This ensures optimal ring seal, reduces blow-by, and maximizes compression for high-performance builds. MAHLE's advanced metallurgy and coating technologies provide excellent wear resistance and heat dissipation for demanding engine applications.

I didn't get the discount code back that appeared when I started my order

Easy...

This includes both sides right and left right?

Please expedite my order - The order was incorrect due to perhaps not know if the part was for the front or rear wheel. I would suggest that your ordering corrects this error. Otherwise, Autoplicity is really great priced service and delivery.

good

so far, will see when part arrives

Thanks my complete order is for a 2000 ford ranger 2.5 thanks

easy checkout

super service

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.

Excellent prices. Delivery was fast. Great site to order parts from.
