Product Details

The Wiseco 4155H is a high-performance replacement piston ring set designed to fit a single piston. Wiseco offers multiple ring configurations across their piston lineup to match the demands of various engine builds, from budget-friendly street applications to high-output performance engines.

Ring Technology by Application:

  • Pro Tru Series: Plasma moly, pre-gapped ring sets engineered for cost-conscious performance builds
  • Sport Compact Series: Features premium NPR XX rings with steel nitrided top rings and Napier-style 2nd rings for enhanced sealing and durability
  • Late Model EFI & Small Block Chevy: Designed around 1.2mm steel nitride and Napier GFX ring sets for tight tolerances and modern fuel injection compatibility
  • Big Block Applications: Utilize a .043" back-cut top ring for added material thickness and improved sealing around the intake valve

Key Features:

  • Replacement/individual ring set — fits one piston
  • Available in plasma moly, steel nitrided, and GFX configurations depending on piston series
  • Napier-style second rings for superior oil control and compression retention
  • Pre-gapped for simplified installation on applicable series

Had the product I needed at a price that couldn't be beat. The shipping was a little high, but not completely out of line, either, and it was still better than other companies who have even MORE ridiculous shipping rates. Will buy from them in the future if they have what I need.

I recently ordered 2 Borla Dual Round Intercooled Tips from Autoplicity.com for one reason and reason only...their prices can not be beat! No where else online can anyone match them! <br>

Great price and fast shipping!

Great prices and easy transaction

Best price I could find on line, shipped really fast. With how low the price is I was worried but everything came fast and it was the correct parts. This place really keeps the cost of racing down.

Everything went seamlessly. I placed my order on a Thursday and it got here Tuesday morning. No problems, and it was the best price I could find.

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!

GOOD PRICE! way to go keep up the good work!!!!
