About CalTeK Power Systems
Specialized eTorque MGU rebuilding backed by real-world repair experience and a commitment to quality.
Who We Are
CalTeK Power Systems is a specialized division focused on professional rebuild services for Stellantis 48-volt eTorque Motor Generator Units. Built on years of hands-on diagnostic and repair experience, we provide professional MGU rebuild solutions for select Ram and Jeep applications through our nationwide mail-in service.
Built on Years of Repair Experience
CalTeK began with a simple focus: diagnose problems accurately, repair them properly, and stand behind the work. After eight years of serving customers through CalTeK Appliance Repair, that same repair-first approach led to the creation of CalTeK Power Systems—a specialized operation dedicated to rebuilding eTorque MGU systems rather than simply replacing expensive OEM assemblies.
Our Rebuild Approach
We believe a professional rebuild starts with understanding why the unit failed—not simply replacing a part and sending it back out. Each MGU is carefully disassembled, inspected, cleaned, rebuilt with upgraded premium-quality bearings and carefully selected replacement components, reassembled, and tested before return.
Built on Years of Repair Experience
From our facility in Cumming, Georgia, CalTeK Power Systems serves customers nationwide through our mail-in rebuild program. Every qualifying rebuild is backed by our 2-Year Limited Warranty, giving customers confidence in the work long after their MGU is returned.
