Product Details

The MAHLE 3030102EB is a bulk pack of 48 plain oil ring expanders designed for use with three-piece oil ring assembly 303-0102B. These expanders are essential components in performance piston ring systems, providing the precise tension and positioning necessary for effective oil control.

Key Features:

  • Replacement expanders from MAHLE oil ring assembly 303-0102B
  • Bulk pack of 48 pieces for high-volume rebuilds and professional engine builders
  • Precision-engineered steel construction for consistent tension
  • Locates oil rails and controls radial pressure against cylinder walls
  • Compatible with MAHLE three-piece oil ring assemblies
  • Allows for proper oil drain-back and oil control in performance applications

The expander acts as a spring between the upper and lower oil rails, creating the necessary tension for proper sealing while allowing optimal oil return to the crankcase. MAHLE expanders are manufactured to exacting tolerances to ensure proper fit and function in demanding performance and racing applications. This bulk pack is ideal for engine shops and professional builders requiring multiple sets.

Great service

Found what I was searching for easily.

Autoplicity simply had the best prices available and everything was in stock to be shipped.

Easy online shopping and checkout. Most important is that the product was exactly what I needed. It was a pleasure doing business with Autoplicity

Found exactly what I was looking for!

Ordered a N-Fab bumper for my Titan. Shipped out quickly and let me know when to expect it in. Price was the best anywhere on the net! Will buy from again, thanks

Quick and easy online shopping and check out. Shipping took long because it had to come from a manufacturer. Also considering the part was small shipping costs seemed high. Everything arrived in order though and part seems just right.

Easy

Good so far.
