The Mahle OE oe piston kit identified by manufacturer part number 2243523WR is designed to restore the specified piston geometry and compression configuration in a measured engine rebuild. Final compatibility depends on the exact engine and measured dimensions, not a similar vehicle name alone.
Key Features
- Marine-style combustion bowl design for consistent combustion quality and heat management under towing and load conditions.
- Cast aluminum construction with expansion-controlled skirt geometry for stable wall clearance across the full operating temperature range.
- Floating 40 mm wrist pins reduce pin bore wear and are included with the set.
- Standard bore (STD), 4.016 in (102 mm), suitable for engines with unworn or freshly honed cylinders at standard dimension.
- 6x cast aluminum pistons (standard bore, marine-style bowl).
- 6x floating 40 mm wrist pins.

Frequently Asked Questions
Will Mahle OE 2243523WR fit my 1989-1998 Dodge Ram 2500?
That vehicle range is listed, but compatibility also depends on the exact engine code, bore, piston design, ring dimensions, oversize, and every current MAHLE application note.
Does this Mahle OE piston kit include piston rings?
The package includes rings only when the exact product specification states they are included. Confirm quantity, oversize, piston orientation, pin hardware, and current MAHLE package contents before machining.
What must the machine shop verify before assembly?
Verify finished bore, piston-to-wall clearance, ring end gaps, piston orientation, pin fit, deck height, valve clearance, compression ratio, bearing clearances, and the intended fuel and duty cycle.
Installation Instructions
Use the current Mahle instructions for part number 2243523WR and the engine builder's measured assembly specifications. A qualified machine shop must verify bore finish, clearances, ring gaps, piston orientation, pin fit, deck height, valve clearance, compression ratio, lubrication, torque procedures, and break-in.
