Got a Stihl 029 or MS290 chainsaw that's lost compression or needs a rebuild? This aftermarket piston kit is a direct replacement for the OEM part number 1127 030 2003. The piston itself is 46mm in diameter, matching the original cylinder size to restore proper engine performance. It's a complete kit (piston, rings, wrist pin, and clips) – everything you need for a top-end rebuild. Made for the gas-powered, 2-stroke engine in these popular Stihl models. While it's an aftermarket part, it's designed to fit correctly and get your saw running strong again without the high cost of a genuine Stihl part. The kit is new and comes in its packaging, ready for a DIY repair or for mechanics to keep on the shelf. Perfect for homeowners, landscapers, or small engine shops looking for a reliable, budget-friendly fix for a worn-out saw.
