Product Details

The Wiseco 4005HF is a high-performance replacement piston ring set designed to fit a single piston. Wiseco offers multiple ring set configurations across their product lineup to match different engine builds and performance requirements.

Ring Set Technology:

  • Pro Tru Series: Features a plasma moly, pre-gapped ring set — an excellent choice for the budget-conscious performance builder
  • Sport Compact Kits: Include premium NPR XX rings, featuring high-quality steel nitrided top rings and Napier-style second rings for enhanced oil control and sealing
  • Late Model EFI & Small Block Chevy Applications: Engineered around 1.2mm Steel Nitride and Napier GFX ring sets for precise fitment and superior sealing in modern fuel-injected engines
  • Big Block Applications: Many sets utilize a .043 back-cut top ring, providing extra material thickness in the intake valve pocket area for added durability under high-load conditions

Important: Unless otherwise noted, ring sets are sold individually and fit one piston. Order the specific quantity needed to complete your engine build.

Wiseco piston rings are engineered to complement Wiseco pistons and deliver reliable sealing, reduced blow-by, and long service life in performance and OEM-replacement applications alike.

the website was easy to use

Everything was running smooth until I got to PayPal portal. It didn't allow me to change my daughter's name. I'm the one buying with my credit card, what's up with that? Thx

I placed my order on a Saturday and by Monday my order was shipped. Autoplicity had the best price I could find on the Thule Apex Swing bike carrier. They also had a great site, reasonable shipping and an easy checkout.

Autoplicity had the lowest price online for the product I needed. I will definitely buy from them again.
