Product Details

The Wiseco 6398LX3905 is a shelf stock forged piston designed for Chevrolet LS series engines. Featuring a 3.905-inch (99.19mm) bore diameter and a -3.2cc flat top (FT) dish, this piston is engineered to deliver reliable performance in street and light performance LS builds without the lead time of a custom order.

Wiseco's shelf stock pistons are manufactured from high-strength forged aluminum alloy using the same processes as their race-proven custom pistons. The flat top design with a slight negative dish provides an ideal compression ratio when paired with common LS cylinder head combinations, making them a popular choice for engine rebuilds and performance upgrades.

Key Features:

  • Bore Diameter: 3.905 inches (99.19mm)
  • Dish Volume: -3.2cc flat top design
  • Application: Chevrolet LS Series engines
  • Construction: High-strength forged aluminum alloy
  • Program: Shelf stock — no custom order lead time required
  • Designed for use with standard LS wrist pins and ring packages
  • Manufactured in the USA by Wiseco, a Founder of the forged piston industry

The 6398LX3905 is sold individually. Confirm bore size, compression height, and pin diameter requirements against your specific block and rotating assembly before ordering to ensure correct fitment for your LS engine build.

good job!

Lowest prices I found on the net and great customer service! Fast shipping too!

Great products, and pricing

Simply awesome. The customer service was actually enjoyable to deal with and their prices are unbeatable (just ask Jegs). I will most definitely be doing business with Autoplicity again.

I ordered a universal Hurst Pistol Grip "shift knob" for my '12 Mustang GT. It squeezed to a perfect fit right where I need to grip it. It improved shift time and accuracy greatly and feels and looks great! Autoplicity had the best price on the web and I got this in 3 business days. I recommend this product.

Order was fast, had the products I wanted in stock, and vehry pleased. Thank you 5 star service.
