Sealed Power WH802CP Engine Piston

Sealed Power WH802CP Engine Piston Overview

Sealed Power WH802CP is a standard-size engine piston built for Jeep 4.0L applications that call for a 3.8750 in. bore and a 1.592 in. compression distance. It uses a hypereutectic alloy construction with a recessed head and DUROSHIELD skirt coating for consistent fit and wear control in service.

Compatible With 1996-2000 Jeep Cherokee, 1996-2000 Jeep Grand Cherokee, 1997-2000 Jeep TJ, and 1997-2000 Jeep Wrangler, this piston is a direct-fit option for common rebuild and overhaul work. The WH802CP part number is also referenced in interchange listings for related applications.

Detailed Description

Sealed Power WH802CP is engineered as a standard replacement piston for Jeep Cherokee, Grand Cherokee, TJ, and Wrangler models listed above. The recessed head profile and hypereutectic alloy construction support precise combustion chamber geometry, while the coated skirt helps maintain smooth cylinder wall contact during operation. With its specified bore, compression distance, and pin dimensions, this piston is suited to engine work where dimensional accuracy matters.

Sealed Power uses modern materials and controlled manufacturing processes to produce engine components that meet demanding service requirements. WH802CP is a single piston listing, and the fitment data should be matched to the engine build specifications before assembly. This part number, WH802CP, is commonly searched for Jeep Cherokee and Jeep Wrangler engine rebuilds where standard-size piston dimensions are required.

This part cross-references 1445P and P830STD for the same application.

Common Repair Uses

• Restoring compression in a worn cylinder during an engine rebuild
• Replacing a damaged piston from detonation, scoring, or heat-related wear
• Correcting piston-to-bore fit during a standard-size overhaul
• Addressing oil control concerns tied to worn ring lands or piston skirts
• Supporting rebuild work on Jeep Cherokee and Jeep Wrangler engines

Installation Notes and Tips

Verify bore size, compression distance, pin diameter, and ring groove dimensions before installation. Minimum clearance is listed on the carton label and should be checked against piston fitting information during machine work. Confirm ring selection and cylinder condition during assembly, and follow the engine builder’s measurement procedure for Jeep 4.0L applications.

Because fitment is specific to the listed Jeep Cherokee, Grand Cherokee, TJ, and Wrangler model years, compare the engine code and rebuild specifications before final installation. Proper cleaning, inspection, and measurement of the block, rods, and rings help ensure correct piston fit.
