Product Details

The Wiseco 7700XX represents Wiseco's commitment to delivering high-performance piston rings engineered for diverse applications. Wiseco offers multiple ring configurations tailored to specific engine builds, from budget-conscious Pro Tru plasma moly pre-gapped ring sets to premium NPR XX steel nitrided rings found in sport compact kits.

Ring Technology:

  • Sport Compact Kits: High-quality NPR XX rings featuring steel nitrided top rings and napier-style second rings for superior sealing and durability
  • Late Model EFI Applications: 1.2mm steel nitride top rings paired with napier GFX ring sets for optimal compression control
  • Big Block Applications: .043 back cut top ring design provides extra material thickness around the intake valve for increased strength
  • Pro Tru Line: Plasma moly pre-gapped rings offer reliable performance for budget builds

Wiseco's advanced ring technology delivers excellent oil control, reduced blow-by, and consistent compression across a wide range of performance applications. Each ring set is precision-manufactured to exacting tolerances for proper sealing and long service life.

Note: Unless otherwise specified, rings are sold individually. Please order the specific quantity required for your application.
