  • Hypereutectic alloy construction for modern engine durability
  • Recessed head design with .116-inch deep recess
  • DUROSHIELD skirt coated piston for reduced skirt wear
  • 1.592-inch compression distance and 0.06-inch pin offset
  • Pin diameter: 0.931 inch / 23.647 mm
  • Ring groove widths: 5/64, 5/64, and 3/16

Detailed Description

Sealed Power WH825CP is an engine piston engineered for Jeep Cherokee, Jeep Grand Cherokee, Jeep TJ, and Jeep Wrangler applications from 1996-2000. It is a standard-size, single piston with a recessed head profile and hypereutectic alloy material, making it a practical choice for rebuilds that require accurate bore match, stable compression height, and controlled skirt clearance. The DUROSHIELD-coated skirt adds a wear-resistant surface where piston-to-cylinder contact matters most. Sealed Power focuses on modern manufacturing methods and quality control to deliver components that meet the demands of current engine service work.

This part cross-references 2229 and 4798329 for the same application. The WH825CP piston is a fitment-based choice for Jeep 4.0L engine service where the original piston specification must be matched closely. Use the part number WH825CP when verifying catalog data for Jeep Cherokee, Jeep Grand Cherokee, Jeep TJ, and Jeep Wrangler rebuilds.

Common Repair Uses

  • Restoring compression in a worn Jeep engine
  • Replacing a damaged or scored piston during overhaul
  • Matching standard bore specifications in a rebuild
  • Addressing piston slap, skirt wear, or ring seal concerns
  • Supporting proper combustion chamber geometry in 4.0L service

Installation Notes and Tips

Confirm bore size, piston-to-wall clearance, and ring groove dimensions before assembly. The carton label should be checked for piston fitting information, since minimum clearance is listed there. Verify the recessed head depth, compression distance, and pin diameter against the engine specification before final installation. For Jeep Cherokee, Jeep Grand Cherokee, Jeep TJ, and Jeep Wrangler applications, match the piston to the correct cylinder and ring package during engine rebuild preparation.

Quality Assurance

Sealed Power states that its parts are produced with leading-edge materials and ISO- and QS-certified manufacturing processes. That manufacturing approach supports consistent dimensional control and repeatable engine service results for WH825CP and other Sealed Power engine components.
