Product Details

The Stewart 23103 Stage 2 Water Pump is engineered for small block Chevrolet applications, specifically designed for 1971-1982 Corvettes with short water pump configurations. Built from exclusive 356-T6 heat-treated aluminum casting, this pump delivers superior strength and thermal management compared to standard castings.

Key Features:

  • 356-T6 heat-treated aluminum construction for enhanced durability and heat dissipation
  • Stage 2 performance modifications for improved coolant flow and efficiency
  • Clockwise rotation design for proper SBC fitment
  • 0.75-inch precision bearing for reliable operation
  • 0.75-inch hardened shaft for extended service life
  • Direct-fit replacement for 1971-1982 Corvette short water pump applications

The Stage 2 design incorporates several performance enhancements over Stage 1 pumps, including optimized impeller design and improved internal flow characteristics. Ideal for stock, OEM restoration, or mild to moderate racing applications where reliable cooling performance is critical. This pump provides the cooling capacity needed for street performance and light competition use while maintaining excellent reliability.

Best prices online! Ordered a JBA performance exhaust and Airaid intake system for my 06 F-150. Was hesitant at first because I never heard of them but ordering was a breeze and saved me over $100 total for two items compared to anywhere else. Had package at my door in about 24 hours and even selected normal UPS ground shipping. Very satisfied and will definitely return!

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

efficient; loved payment through Amazon
