Description JE 207481R Piston Single Ultra Series (4.035 in. Bore, 1.000 in. CH, -1.80 CC) for CHEVROLET Small Block Engine
JE Ultra Series forged Pistons are among the industry’s strongest and most fully featured off-the-shelf Pistons. Designed for domestic applications from LS to Big Block and HEMI to Ford Modular, they feature JE’s proprietary Aligned Grain Flow forging technology for next-level tensile strength under extreme cylinder pressures.
Ultra Series Pistons include custom-level features for boost-heavy or nitrous V8 engine builds. All JE Ultra Series Pistons are made 100% in the USA.
- Designed for Power: Every feature is optimized for high-Horsepower / HP racing engines. Aligned Grain Flow technology maximizes tensile strength for high-performance engine environments.
- Piston Coatings: Skirt coating reduces friction, Wall wear, and operating noise, especially during cold starts. The ceramic-based thermal barrier crown coating reduces Piston crown temperatures and improves exhaust gas scavenging.
- High-Strength Wrist Pins: Premium thick-Wall Wrist Pins are manufactured by Trend Performance in the USA and Designed for high-performance and power-adder builds.
- Gas Ports and Pin Oiling: Lateral gas ports help maintain top compression ring seal at high RPM and boost. Enhanced oiling keeps the Wrist Pin, pin Bore, and small end lubricated to reduce heat, friction, and wear.
