Product Details

The MAHLE 51709CP.030 is an OE-replacement piston ring set designed for the small block Chrysler/Dodge 318 cubic inch (5.2L) Magnum V8 engine. This set is engineered for a 3.94" bore (+.030" oversize), making it the ideal choice for engines that have been bored 30 thousandths over standard during a rebuild. The set covers all 8 pistons.

MAHLE piston rings are engineered to exacting OE standards, with ring materials, coatings, and tension levels optimized for reduced friction, minimal oil consumption, and extended service life. The compression rings feature a barrel-faced contact area for efficient sealing, while the oil control ring assembly provides outstanding oil drain-back performance.

  • Upper Compression Ring (UCR): Cast Iron | Ring Type: BT-10 | Axial Height: 5/64"
  • Lower Compression Ring (LCR): Cast Iron | Ring Type: BT-10 | Axial Height: 5/64"
  • Oil Control Ring (OCR): Stainless Steel | Chrome Facing | Ring Type: CP-20 C7 Shallow Groove | Axial Height: 4.0mm

Key Features:

  • OE-quality materials and coatings for reliable, long-lasting performance
  • Engineered for +.030" overbore applications
  • CP-20 oil ring assembly with exclusive 20-degree ear angle for superior cylinder wall sealing
  • Chrome-faced oil control ring for durability and oil management
  • Complete set for all 8 pistons
