Product Details

The Wiseco 6445RX3903 is a Professional Series shelf stock forged piston designed for the Chevrolet LS engine family. Featuring a -15cc reverse dome (R/Dome) crown, a 3.903 in. bore diameter, and a 1.110 in. compression height, this single piston is engineered to deliver precision fitment and maximum performance in high-output and race-built LS applications.

Key Features:

  • Bore Diameter: 3.903 in.
  • Compression Height: 1.110 in.
  • Pin Diameter: 0.927 in.
  • Crown Volume: -15cc Reverse Dome (R/Dome)
  • Sold as: Single piston (shelf stock)
  • Material: 2618 high-strength aluminum alloy for superior tensile strength and heat resistance
  • ArmorGlide? Skirt Coating: Reduces friction, resists seizure, and promotes quieter operation
  • Fully machined crown features with precision ring grooves for maximum ring seal and minimized blow-by
  • Valve pocket design allows maximum airflow around valves and accommodates oversized valves and high-lift camshafts
  • Engineered, forged, and machined in the USA at Wiseco's Mentor, Ohio facility

Wiseco's Professional Series pistons are no-expense-spared components built for serious engine builders tackling heavy to severe-duty race builds. The R/Dome crown geometry is optimized for detonation resistance and improved quench characteristics during the compression and combustion cycle, contributing to increased horsepower potential and longer engine life. This shelf stock piston ships ready to install and is compatible with standard LS rod and pin combinations using the 0.927 in. pin diameter.

Very high level of responsive customer service, wow! And the items arrived immediately, so fast I thought there might be a mistake. :D<br>thx Sean!

My dealings with this site have been great. I made a mistake on my address and emailed them to change it. I got quick responses every time. Would definitely use the site again.

great prices & shipping

My first order and I must say, very impressive! Awesome prices and super-fast shipping direct from the manufacturer. Couldn't ask for more! I will return.

This was my first order with Autoplicity. Their prices were great, and the ordering process very easy. I was a little frustrated at first, as the order didn't arrive as expected. When I called, it took a little work, but I finally got the info that it was shipping from the manufacturer, and did get the tracking info. The parts arrived when tracking said it should. Would I place another order with Autoplicity? Short answer is yes!

Purchased K&N Filter. Excellent price and received filter as scheduled.
