The Boss Hog Story:
Built by Racers, for Racers
Boss Hog Torque Converters is the high-performance converter line built by ACC Performance Products Plus Inc., a veteran-owned, engineering-based manufacturer founded by Nelson Gill in Muscle Shoals, Alabama.
For more than 50 years, we've focused on one thing: building torque converters matched to a customer's exact combination, not a generic catalog recommendation. Every converter is engineered, assembled and quality-checked in the USA.
Nelson oversees every part of the operation, from manufacturing and process improvement to quality control and production. That hands-on engineering focus is why racers, builders and transmission shops across the country trust Boss Hog to get the converter right the first time.
Our Mission
At Boss Hog, we believe every performance build deserves a torque converter matched to its exact combination. That's why we're committed to:
92 quality-control steps
on every converter we build
Custom-matched converters built
for your exact combination
Honest technical support
before and after the sale
Made in the USA and trusted
by racers and builders since 1970
What Makes Boss Hog Different?
We're not a faceless catalog or an online warehouse. When you call Boss Hog, you talk to someone who understands engines, transmissions and how a converter actually behaves behind your combination. We don't just look up a part number. We help you understand why a given stall speed and converter design is the right choice for YOUR vehicle and how you drive it.
Our team is engineering-driven and detail-obsessed. Every converter passes 92 quality-control steps before it ships, because we know a converter has to be right the first time. That's the standard we've built at Boss Hog.
