JE Pistons Piston Kit 4.030 1.125 CH Chevrolet Small Block

Provides reliable reciprocating assembly with the JE Pistons Chevrolet Small Block 4.030in Bore 1.125in CH -5.00 CC Piston Kit, delivering forged 4032 aluminum alloy strength for consistent durability and service life in demanding applications.

JE Pistons' Sportsman Racing Products (SRP) line combines the manufacturing pedigree of a proven motorsports supplier with a focus on accessible performance and cost-effective solutions. These SRP pistons are forged from 4032 aluminum alloy and engineered to reduce machining requirements while maintaining the core benefits of a forged design.

Key technical features and functional benefits:

• Forged 4032 aluminum alloy — provides a balance of strength and thermal stability; relevant for resisting deformation under elevated cylinder temperatures and improving long-term reliability.
• SRP Sportsman Racing Products design — bridges the gap between high-quality forged piston performance and affordability; useful for builds where performance durability is required without premium-tier cost.
• Manufactured to reduce machining — lowers preparatory engine work and helps shorten assembly time; this reduces shop labor and potential for machining-related variance.
• Application-specific dimensions (4.030in bore, 1.125in crown height, -5.00 CC dome) — matches specified Chevrolet small block requirements to ensure correct combustion chamber volume and piston-to-wall fit for the intended bore size.
• JE Pistons brand engineering — leverages JE Pistons' racing experience and quality control processes, supporting predictable performance and consistency across production pieces.

Materials and manufacturing focus on functional value: the chosen 4032 alloy and forged construction target a practical combination of fatigue resistance and thermal conductivity while enabling cost efficiencies compared with higher-alloy or exotic designs.

Use this piston kit where a dependable, forged replacement or upgrade is required for Chevrolet small block applications that call for the specified bore and dimensional set. JE Pistons' SRP approach emphasizes repeatable manufacturing, reduced preparatory machining, and accessible performance for engine builders and technicians.
