Product Details

The Wiseco K456X3 is a Professional Series forged piston set engineered for Chevrolet LS engines, featuring a 4.030-inch bore, 1.110-inch compression height, and a -20.00cc dish volume.

Key Features:

  • 2618 Forged Aluminum Construction — Engineered, forged, and machined in the USA from 2618 aluminum for superior tensile strength and durability under extreme heat and pressure
  • ArmorGlide® Skirt Coating — Proprietary skirt coating reduces friction, improves seizure resistance, and promotes quieter engine operation
  • Fully Machined Crown — Precision-machined crown enhances combustion chamber efficiency and ensures consistent compression across all cylinders
  • Anti-Detonation Groove — Designed to improve ring seal performance and reduce the risk of detonation in high-boost or high-compression builds
  • Forced Pin Oiling — Ensures effective wrist pin lubrication under sustained high-RPM and severe-duty conditions
  • Premium Ring Set Included — Each kit includes eight pistons, a complete premium ring set, and wrist pins
  • 4.030 in. Bore | 1.110 in. Compression Height | -20.00cc Dish — Ideal for 4.000-inch stroker combinations in Chevy LS platforms

Wiseco's Professional Series pistons are shelf-stock components built to custom-level tolerances, making the K456X3 an ideal choice for serious engine builders targeting heavy-duty to severe-duty race applications including turbo, supercharged, and nitrous-assisted LS builds.

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

The best price I could find and it arrived in 2 days! I'll be doing business again.

I'll comment once item is received

They have the best prices and fast shipping too.

Was great!

Ordered the Auto Ventshade Ventvisor Deflector 4 pc. (Model 94856) for my 2000 Toyota Camry XLE. Was easy to install with no tools, just use the included strong double sided adhesive tape. Instructions that came with it could've been more detailed on where exactly to install the ventshade as I had to remove them tediously, realizing I had to put them a little higher. Also, there seems to be an unsightly gap between the front and back windows. Works as designed. Satisfied with product. Fast shipping by Autoplicity.

Unbeliveable customer service and super fast shipping. I had a question about my order and I was able to use the online chat function to instantly connect with a customer service agent that was quick to answer all my questions regarding my order. I am very pleased with the level of service I received not to mention the great price they offered on the item I purchased. I will be sure to continue doing business with Autoplicity for my automotive needs. Thanks so much. A+
