Hypereutectic Piston Set, 4.040" Bore

Constructed from either 4032 or 390 aluminum alloy, these pistons offer superior strength, scuff resistance, and protection against seizure, ensuring long-term reliability. Each piston in the 3237HC.040 set features a proprietary diamond-finished skirt. This unique process reduces friction and wear, contributing to smoother operation and extended engine life. The pistons have a specified bore of 4.040 inches and a compression height of 1.605 inches, designed for precise fitment and optimal performance within compatible engine configurations. These aftermarket pistons are a direct replacement for specific engine builds, particularly noted for their application in Chrysler/Dodge 8.0L V10 engines from 1994-2001. Their robust construction makes them suitable for performance-oriented engine rebuilds where durability and strength are paramount. Piston rings are not included with this set and must be purchased separately.
