Detailed Description

The Sealed Power WH822CP engine piston is built for engines that require a standard-size replacement piston with a 3.8750 in. bore and recessed crown profile. Its hypereutectic alloy construction and skirt coating are selected to support consistent fitment, controlled expansion characteristics, and dependable wear resistance in everyday engine operation. This part number WH822CP is listed for Dodge Dakota, Jeep Wrangler, Jeep Cherokee, and Jeep TJ applications across the model years shown.

Sealed Power uses modern manufacturing methods and ISO- and QS-certified production practices to deliver engine components that meet demanding application requirements. This piston is a practical choice when rebuilding or servicing engines that call for the specified compression distance, pin dimensions, and ring groove layout.

This part cross-references Monroe Shocks & Struts (e.g., 1445P, P830) for the same application.

What This Piston Helps Address

  • Restores proper cylinder sealing in worn or damaged bores
  • Addresses low compression caused by piston wear or crown damage
  • Helps correct oil control issues related to piston and ring groove wear
  • Supports rebuilds where standard-size piston dimensions are required
  • Replaces a piston with the specified recessed-head configuration

Installation Notes and Tips

Verify bore size, compression distance, pin diameter, and ring groove widths before installation. Minimum clearance is listed as “see piston fitting information on carton label,” so confirm piston-to-bore clearance during engine assembly. Match the piston to the correct ring set and follow the engine builder’s measurement and break-in procedures for the application.

Quality Assurance

Sealed Power manufactures engine parts using leading-edge materials and certified production processes to support consistent dimensional accuracy and application-specific performance. WH822CP is a standard-size piston built to the listed specifications for the confirmed Dodge Dakota and Jeep fitments.
