Product Details

The MAHLE 4135ML-043 is a file-fit piston ring set designed for a 4.130-inch bore diameter with +.005" oversize tolerance. Engineered to MAHLE's rigorous OE and performance standards, this ring set delivers consistent sealing, thermal management, and oil control in high-performance and rebuilt engine applications.

The set features a .043-inch top compression ring, a .043-inch second compression ring, and a 3.0mm oil control ring. As a file-fit design, the end gaps are intentionally left oversized to allow the builder to precisely fit each ring to the specific bore, ensuring optimal performance and longevity.

Key Features:

  • Bore Size: 4.130" +.005" oversize
  • Top Compression Ring: .043" (approx. 1.09mm)
  • Second Compression Ring: .043" (approx. 1.09mm)
  • Oil Control Ring: 3.0mm
  • File Fit: End gaps require filing for precise bore fitment
  • Manufactured by MAHLE, a globally recognized OE and performance engine components supplier
  • Ideal for engine rebuilds and performance builds requiring precise ring gap control

MAHLE piston rings are manufactured to exacting tolerances using high-quality materials, ensuring reliable compression, reduced blow-by, and excellent oil control. The file-fit design is preferred by professional engine builders who demand full control over ring end gap specifications.

Great prices and quick shipping! They kept me informed of when the item was shipped also. Couldn't be happier!

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

Great price on a great product! The Thule Raceway 9002 3-bike trunk-mounted rack is what I purchased. Shipping was fairly quick and the product was new, in original packaging and was a great deal compared with other sites for the same product! Would order again!

Took a long time to ship. But was a great deal for the price of the product will order again.

Was linked here by Amazon. I found the absolute best price on the item I was looking for, I had a confirmation as soon as I ordered it, and shipping as prompt. I would definitely recommend these guys and will be shopping here myself in the future.

smooth transaction. good seller.

"Excellent price and great customer service. Order was shipped promptly!! Would do business with them again. "

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!
