Our Heavy Duty Solutions

  • MAHLE offers a comprehensive range of CLEVITE wet and dry cylinder sleeves, including the required O-ring kits for many applications.
  • All sleeves are engineered to meet or exceed OE specifications for material construction and hardness, ensuring reliable performance and durability.
  • CLEVITE cylinder assemblies are installation-ready and include a liner or finned cylinder with the appropriate seals, along with pistons, rings, and circlips when required.
  • Depending on the engine application, assemblies feature either a finish-machined or rough-turned cylinder bore.
  • For engines that use dimension groups, color coding, or letter classifications, MAHLE CLEVITE maintains the original manufacturer identification system for accurate fitment.

  • MAHLE offers a broad range of heavy duty pistons, including cast-iron, aluminum, FERROTHERM and MONOTHERM designs to meet varying engine performance demands.
    • FERROTHERM pistons combine a forged steel crown with an aluminum skirt and utilize MAHLE's patented shaker plate design to improve crown cooling and durability.
    • MONOTHERM pistons feature a one-piece forged steel construction that simplifies installation while delivering exceptional endurance and performance.
  • Many CLEVITE aluminum pistons feature Ni-Resist groove inserts, which reduce groove wear and extend piston life, with ultrasonic testing ensuring bond integrity and quality.
  • Additional piston enhancements can include heat plugs, friction-reducing skirt coatings, and hard-anodized crowns for improved heat resistance and durability.

  • CLEVITE piston rings are application-engineered and pre-lapped for immediate seating, delivering a superior seal with minimal friction.
  • Manufactured to precise tolerances, they help maintain combustion chamber sealing while controlling oil consumption in demanding heavy duty engines.
  • Exclusive technologies such as Gray Armor™ piston rings with PC380 coating and C3™ ring sets provide enhanced durability.
  • Gray Armor™ coatings offer exceptional wear resistance, reducing liner and ring wear by up to 75% when paired with hardened liners.
  • C3™ ring sets feature nitrided steel oil rings that improve oil control, resist embedment, extend ring life, and eliminate the need for chrome plating.
  • Designed for durability, easier installation, and reduced oil consumption, these OE-quality solutions are also available for foreign nameplate applications under the MAHLE brand.

  • CLEVITE heavy duty bearings include rod, main, and cam bearings engineered for the demanding conditions of commercial and industrial engines.
  • Most rod and main bearings feature CLEVITE's proven tri-metal CL-112 construction, designed for strength, durability, and long service life.
  • CLEVITE cam bearings are precision-bored and ready for installation, eliminating the need for additional machining.
  • Their advanced construction combines a steel backing, copper-lead alloy, nickel barrier, and babbitt overlay to deliver low-friction conformability and durability.
  • Extensively tested and rated to 12,000 psi, CLEVITE bearing materials provide reliable performance across a wide range of heavy duty engine applications.

  • CLEVITE heavy duty engine parts support a wide range of Transportation, Construction, Agricultural, and Power Generation applications.
  • Known for OE-quality performance, the lineup combines dependable durability, competitive pricing, strong availability, and comprehensive warranty support.
  • Beyond core engine components, MAHLE offers an extensive selection of replacement parts for complete engine rebuilding and repair needs.
    • Available products include camshafts, crankshafts, gear trains, lifters, valves, rocker arms, springs, head bolts, injector O-rings, and other critical engine components.
  • Backed by industry-leading service and engineering expertise, CLEVITE is a trusted brand for heavy duty engine parts across a wide range of applications.
  • For foreign nameplate engines, the same OE-quality heavy duty solutions are available under the MAHLE brand.
