This product is a set of SH Engines 28 Wrist Pin Clips designed for securing the wrist (piston) pin in SH .28 nitro RC engines. Wrist pin clips (also known as circlips or retaining clips) fit into a groove in the piston bore to hold the wrist pin in place and prevent it from sliding out during engine operation, which could otherwise cause internal engine damage. The clips are made from spring steel and are sized specifically for the SH .28 engine applications. They are typically sold in pairs and are essential replacement parts when rebuilding or servicing the top end of compatible engines.
Features:
• Retaining clips for SH .28 engine wrist pin
• Spring steel construction for secure retention
• Fits into piston groove to prevent wrist pin movement
• Sold in a pack of 2 clips
• Essential for engine top‑end rebuilds or maintenance
• Helps protect engine internals from damage due to pin movement
