Product Details

The Wiseco 6398RX3 is a shelf-stock forged piston designed for Chevrolet LS Series engines. Featuring a -3.2cc flat top (FT) dish, this piston is engineered to deliver consistent compression ratios and reliable performance in street and performance LS applications. As a shelf-stock unit, it is ready to ship without the lead time associated with custom forged pistons.

Wiseco manufactures this piston using their proprietary forging process, producing a piston that is significantly stronger and lighter than cast alternatives. The forged aluminum construction provides superior strength-to-weight ratio, improved thermal resistance, and enhanced fatigue life under demanding conditions.

Key Features:

  • Application: Chevrolet LS Series engines
  • Dish Volume: -3.2cc flat top design for optimized compression
  • Construction: Forged aluminum for superior strength and durability
  • Type: Shelf stock — no custom lead time required
  • Manufacturer Part Number (MPN): 6398RX3
  • Designed for high-performance street and race LS engine builds
  • Wiseco's proven ArmorGlide skirt coating reduces friction and wear
  • Precision CNC machined to tight tolerances for proper ring seal and ring land integrity

The Wiseco 6398RX3 is an ideal choice for enthusiasts and engine builders looking to upgrade or rebuild a Chevy LS powerplant with a reliable, performance-grade forged piston. Wiseco's shelf-stock program means you get professional-quality forged pistons with fast availability.

So far, they did good getting my package to me...downfall it was opened from whoever was subcontracted to send it to me. however they promptly have provided me with a return slip and we will see where it goes from there. they were quick to help fix their problem as long as i had pictures of what was wrong. still cheaper than anywhere else.

This is the first time I ordered from Autoplicity. Very good experience overall. The prices are the best I can find anywhere online. It was shipped very quickly, and I received my item just in time before my trip. Thanks!

right parts, right price

Autoplicity best price on the web,FAST delivery, ordered wed. afternoon and received friday. AAAA++ RATING Will be ording from in the near future.

Easy ordering and when i did have a question they answered right away! best price on the product too!

I ordered some floor mats for a Prius. Autoplicity was very competitive in their pricing. Not only that, they shipped quickly and had great feedback during and after I ordered. I would purchase from them again!

After placing my order, my item was shipped out the next business day as promised. Great service and great products, what more could you ask for!!
