These pistons are the ideal replacement for your Hemi 6 rebuild; these are made of a very strong alloy called hypereutectic aluminium alloy. 
 

They also feature high quality precision finishing and T5 heat treatment; this alloy blend and treatment allows the pistons to withstand much higher heat with minimal expansion with increased strength than what you would find in a standard cast replacement.
 

These will suit all rebuilds from standard through to an E49 specification with no problems (not recommended for race use). 
 

Piston Specifications:
 

• Compression height: 1.692"
• Ring grove sizes: 5/64" - 5/64" - 3/16"
