Detailed Description

Part number 2C4639 is an engine piston ring set for Volkswagen CC, Tiguan, Beetle, Eos, Golf, Jetta, Passat, Bora, Pointer, and Cabrio applications listed in the fitment data. The ring package includes a chrome top ring, a phosphate-treated second ring, and a steel rail/stainless expander oil ring arrangement to support compression sealing, oil control, and cylinder wall contact. With a 3.248-inch bore size and standard oversize specification, it matches the engine dimensions shown in the product data.

This part cross-references Monroe Shocks & Struts (e.g., 06A 198 151 C, 08-435100-10) for the same application.

What It Is Used For

  • Restoring compression loss caused by worn piston rings
  • Reducing oil consumption linked to ring wear or poor sealing
  • Addressing blow-by from damaged or fatigued ring surfaces
  • Replacing rings during an engine rebuild or top-end service
  • Correcting cylinder sealing issues in high-mileage Volkswagen engines

Installation Notes and Tips

Verify bore size, groove dimensions, and ring end gap before installation. Clean the piston grooves thoroughly and inspect the cylinder walls for scoring or taper before assembly. Confirm the fitment notes for the exact Volkswagen engine application, since the catalog lists multiple model years under part number 2C4639.

Quality Assurance

Use this part only where the listed bore and groove specifications match the engine. The chrome and phosphate surface treatments, along with the steel ring construction, provide the material and finish details needed for a proper rebuild selection.
