Our Story

Haggai 2nd Generation

Welcome to Haggai Second Generation (H2G), a legacy that began in 1986 with Jerry’s dream of entrepreneurship. In 2014, that dream materialized as Haggai Automotive & Diesel Repair. Growing from a small diesel repair shop into Haggai Truck Center, we’ve emerged as a nationwide leader in Cummins ISX engine repairs.

Today, Jerry’s children proudly carry forward his dreams, leading to the establishment of Haggai Second Generation in 2023. As a family-owned business nestled in Griffin, Georgia, we thrive on our unique passion for working on Cummins ISX engines and we can not wait to officially lunch in 2024!!!!

Our commitment to excellence propelled us to specialize in engine building, more specifically the ISX Cummins Engine. Exclusively using OEM parts, rebushed rods, cutting counterbores, and meticulously resurfacing components like exhaust manifolds, we ensure a perfect seal upon reinstallation. Each engine is crafted to specific Cummins ISX engine CPL, reflecting our unwavering dedication to perfection.

Faith is the cornerstone of our operations at H2G. Our goal is to get you back on the road as soon as possible. Whether you’re in our local community or across the nation, trust us with your Cummins ISX engine needs, and experience 100% dedication to craftsmanship. With nationwide shipping capabilities, we’re here to turn your ISX engine build into reality.

We Were Born For This!
