Product Details

The JE Pistons J200U8-46005 ProSeal Piston Ring Set is a premium, race-proven ring set engineered for 8-cylinder engines with a 4.600-inch bore. Built around JE's J200 Ultra Low Tension design, this matched set features a .043-inch top ring, 1/16-inch second ring, and 3/16-inch oil ring, delivering exceptional combustion sealing with minimal friction losses.

Key Features:

  • Top Ring: Ductile iron barrel-face construction with a plasma-moly inlay — combining molybdenum, nickel, chrome, and trace elements for superior wear resistance and reduced friction
  • Second Ring: Phosphate-coated cast iron taper-face, reverse torsional (D-wall) design for enhanced sealing and gas control
  • Oil Ring: Ultra low tension design minimizes parasitic drag without sacrificing oil film control
  • File Fit: Allows precise end-gap tuning to match specific engine build requirements
  • Sold as a Matched Set: Includes rings for all 8 cylinders — the 6th digit of the part number indicates the number of rings per set
  • Available for racing, street performance, and powersports applications across a wide range of bore sizes

JE's ProSeal ring program draws on decades of motorsport engineering, trusted by top competitors in NASCAR, NHRA, ALMS, and AMA events. Part number J200U8-46005 is ready to complement any JE piston build or serve as a precision upgrade in high-performance engine builds requiring a 4.600-inch bore specification.

Very easy and intuitive!

I sent my order for some comp cams lifters on Monday 1-16-2012 at around 8:30 and the Item was still shipped on the next day Tuesday. This was awesome. I received my product on 1-19-2012. They have had the fastest turn around time that I have ever delt with. I would highly recommend them for your auto parts needs. They also had the cheapest price I could fine, including the shipping fee.<br>I like the fact that they sent me an e-mail that my item had shipped and gave the shipping number for tracking.

great service. Been looking for this trounce product for over a year. best hand cleaner i have ever used. makes the orange stuf seem like using just water.

Quick shipping, nice easy to use web site, and the lowest price with shipping around.. will use again..

I am impressed with they mail order service. Recommended.
