Technical Details and Construction
The WH825CP piston from Sealed Power is manufactured using hypereutectic material, which provides enhanced wear resistance and thermal stability compared to conventional cast pistons. The recessed head type with a .116 inch deep cavity supports efficient combustion and helps maintain proper compression ratios. The duroshield skirt coating reduces friction and wear between the piston and cylinder wall, contributing to longer engine life. Pin diameter and offset are engineered to reduce piston slap and improve overall engine smoothness. This piston is designed to meet the exacting standards required for Jeep Cherokee, Grand Cherokee, TJ, and Wrangler engines with a 3.8750 inch bore.
Compatible Jeep Models and Applications
This engine piston is compatible with the following Jeep models:
- Jeep Cherokee
- Jeep Grand Cherokee
- Jeep TJ
- Jeep Wrangler
It is intended for use in standard size engine rebuilds where a direct replacement piston is required. The WH825CP part number ensures proper fitment and performance for these specific Jeep applications.
Common Issues Addressed by the WH825CP Piston
- Worn or damaged pistons causing loss of compression
- Excessive piston skirt wear leading to engine noise
- Overheating issues due to poor thermal conductivity of older pistons
