Eagle Specialty Products Balanced Street Performance Rotating Assembly Chevy Seal

The Eagle Specialty Products Balanced Street Performance Rotating Assembly line gives Chevy small block builders a complete crankshaft, rod and piston kit. It is aimed at street and street/strip engines where affordable performance and reliability matter. These engine rotating assembly kits are balanced by Eagle, so they are ready for assembly.

Key Features:

• Eagle cast steel crankshaft built for dependable street and strip use
• Eagle SIR 5140 steel I-beam connecting rods
• Piston options include cast, hypereutectic or forged aluminum, depending on the kit
• Moly ring sets and performance rod and main bearings from established makers such as King or Clevite
• Balanced by Eagle: assembly part numbers beginning with "B" require no additional balancing
• Seal-specific design for Chevy small block engines with either a 1-piece or 2-piece rear main seal
• Internal or external balance versions are available

Accessories such as the camshaft, timing set, oil pump and gaskets are generally not part of these assemblies. Eagle designed the line for engines making moderate horsepower, with a good balance of performance, durability and value. It suits a street performance or street/strip engine build.
