Product Details

The Wiseco K454X7 is a shelf-stock forged piston kit designed for Chevrolet LS series engines. Wiseco's shelf-stock piston kits deliver the strength and precision of a forged piston with the convenience of off-the-shelf availability, making them a popular choice for performance street and track builds.

These pistons feature a -14cc dish valve-relief design, which reduces compression slightly — ideal for forced induction builds (supercharged, turbocharged, or nitrous) or high-compression naturally aspirated combinations using aftermarket cylinder heads. The forged aluminum construction provides superior strength and thermal stability compared to cast pistons, helping them withstand the higher cylinder pressures generated in performance applications.

Key Features:

  • Forged aluminum construction for maximum strength and durability
  • -14cc dish/valve-relief design for tunable compression ratios
  • Designed specifically for Chevrolet LS series engines
  • Shelf-stock availability for fast turnaround and easy ordering
  • Tight manufacturing tolerances for proper ring seal and long service life
  • Compatible with standard LS bore diameters (verify bore size against full part number specifications)
  • Includes full piston set as specified by kit configuration

Wiseco has been a trusted name in high-performance forged pistons for over 75 years, supplying components to professional racing teams and performance engine builders worldwide. The K454X7 kit is an excellent foundation for any LS engine build requiring proven forged piston performance.

great fast shipping best price even with high shipping fees

Have not received item yet but company is very responsive with fast shipment. Excellent price too.

Ordered Sunday and recieved product Tuesday .. What more can u ask for? Great Seller!

The Best Pricing online period! The shipping was very reasonable with great communication and tracking number proviced. My parts were boxed well and arrived right on schedule. This was my first purchase with Autoplicity but will for sure not be my last.

I ordered a bike rack and the rack was shipped promptly, and was exactly what I ordered. Best price on the internet

Had a great first experience with Autoplicity. I ordered my package late in the day on Wednesday and it was at the front door Thursday! Another big plus is that their prices are hard to beat. Won't have a problem ordering from them again!

Product was shipped super fast. And product was in a well packaged box and everything was there. I would do business with them again in the future. Highly recommended and lowest prices!!!
