Elring 488.030 Engine Crankshaft Seal

Elring 488.030 is an engine crankshaft seal built for rear transmission-side applications where reliable sealing around the crankshaft is critical. It uses PTFE and ACM materials, a dust lip, and a left-hand twist swirl design to support consistent sealing performance in a wide range of Chrysler, Dodge, Jeep, and Ram vehicles.

Key Features

• PTFE (polytetrafluoroethylene) and ACM (polyacrylate rubber) construction
• Inside diameter: 100.0 mm
• Outside diameter: 120.4 mm
• Thickness: 11.0 mm
• Dust lip included for added sealing protection
• Radial shaft seal design: AW/BS
• Swirl type: LD, left-hand twist
• Elring part number 488.030 for direct identification

Detailed Description

This Elring crankshaft seal is specified for rear, transmission-side locations on many Chrysler 300, Dodge Charger, Dodge Challenger, Dodge Durango, Jeep Grand Cherokee, and Ram 1500/2500/3500/4000 applications. The PTFE sealing surface is paired with ACM rubber to balance low-friction sealing with durability, while the dust lip helps protect the sealing edge from contamination. If you are replacing a rear main seal on a 2019-2024 Ram 1500 or a 2012-2021 Jeep Grand Cherokee, Elring 488.030 provides the dimensional and design details needed for the correct application.

This part cross-references Mopar 53021338AB for the same application.

What It Helps Address

• Rear engine oil leakage at the crankshaft seal area
• Oil seepage at the transmission-side seal location
• Contamination entering the seal lip area
• Seal wear from age, heat, and crankshaft movement
• Replacement needs during engine or transmission service

Installation Notes and Tips

Confirm the seal dimensions, swirl direction, and rear transmission-side position before installation. Clean the crankshaft sealing surface and housing thoroughly, and inspect for grooves or damage that could affect sealing. Because PTFE seals are sensitive to handling and installation method, follow the vehicle service procedure for the correct installation depth and orientation. Verify fitment carefully on Chrysler 300, Dodge Charger, Jeep Grand Cherokee, and Ram truck applications before assembly.

Quality Assurance
