BBTV 4735 Engine Piston Ring

Engine Piston Ring Overview

Engine piston ring 4735 is a standard-size ring set application for select Dodge and Jeep engines with a 3.910-inch bore. It uses grey iron top and second rings, a chrome-treated first oil ring, and phosphate surface treatment on the compression rings for controlled wear characteristics.

Key Features

• Standard oversize specification for 3.910-inch / 99.31 mm bore applications
• Grey iron top ring and second ring construction
• Chrome-treated first oil ring for oil control performance
• Phosphate surface treatment on the top and second rings
• Shallow oil groove note for matching engine configuration

Detailed Application Information

Part number 4735 is built for engines used in Dodge Ram 1500, Dodge Dakota, and Jeep Grand Cherokee applications, along with additional Dodge truck and van platforms listed in the fitment data. The ring package is specified with a shallow oil groove note and standard bore sizing, making it a direct match for engines that require this exact ring profile and surface treatment combination. Part number 4735 is also cross-referenced to SWC10020 for the same application.

What This Part Helps Address

• Excessive oil consumption from worn or incorrect oil control rings
• Loss of cylinder sealing from ring wear or mismatch
• Compression leakage that can affect engine performance
• Oil control issues in engines with shallow oil groove requirements
• Fitment problems caused by incorrect bore size or ring profile

Installation Notes and Tips

Verify bore size, groove dimensions, and ring orientation before installation. Confirm the engine matches the 3.910-inch standard bore specification and the shallow oil groove note shown in the fitment data. Proper ring end gap measurement and cylinder preparation are important for correct sealing and service life.

Quality Assurance

Use this piston ring set only where the listed fitment and engine specifications match the application. The phosphate and chrome surface treatments, along with grey iron construction, provide the material and finish details needed for accurate engine assembly.
