When buying a Cummins generator set, many customers feel confused. Why does the same “Cummins” model vary by tens of thousands of yuan? The answer isn’t in the engine alone. Instead, it lies in three critical areas. This guide breaks down the Cummins generator price difference clearly. It exposes hidden risks of low-priced units and explains why “cost-effectiveness = quality + service” matters most for smart purchases. With GoCummins’ transparent pricing and original configurations, you can avoid pitfalls and invest in reliable power.
Customers often ask during purchase: “With the same Cummins engine, why sells Company A for 150,000 yuan and Company B for 200,000 yuan?” In fact, the price gap doesn’t come from the engine. It centers on three key links—one reason GoCummins insists on “transparent pricing and original configurations.”
1. Engine: Original New vs. Refurbished/Assembled
GoCummins equips all units with genuine Cummins engines. These engines have complete traceability codes and a 2-year/500-hour warranty. You can verify their authenticity via the Cummins official genuine engine verification page using the serial number.In contrast, low-priced units often use refurbished engines. These are taken apart and reassembled from old equipment. While they look identical to new ones, their core components (like crankshafts and pistons) suffer severe wear. This leads to extremely high failure rates. Over time, maintenance costs far exceed the initial price difference.

2. Generator: Copper Core vs. Aluminum Core—Is Power Sufficient?
The generator acts as the “heart of electrical energy conversion.” Moreover, its material directly impacts efficiency and lifespan.
- Copper core generators (standard for GoCummins) offer high efficiency (≥95%). They also have a long service life (over 10 years) and stable power output. On the other hand, aluminum core generators—common in low-priced units—have low efficiency (≤85%). They’re prone to overheating and burning out.
- To eliminate shoddy craftsmanship, GoCummins uses only genuine Cummins copper core generators. Explore our genuine Cummins generator components for details.
3. After-Sales Guarantee: National Warranty vs. Local Small Workshops
Low-priced units typically mean “one-time transactions.” Their after-sales support relies solely on local small repair shops. This causes two big problems: shortages of genuine parts and unqualified technical support.
In comparison, GoCummins leverages Cummins’ national service network. We have over 200 service stations across the country. Our after-sales response time is ≤4 hours. During the warranty period, we also provide free maintenance and replacement of original parts.

Summary
When buying a generator set, cost-effectiveness equals quality plus service—not just low prices. A cheap initial cost may hide huge follow-up expenses: engine failures, frequent repairs, and downtime losses.
GoCummins makes three clear promises:
- First, all unit configurations are transparent. You can verify engine serial numbers and generator models anytime.
- Second, prices are public with no hidden fees.
- Third, national after-sales support lets you buy with confidence and use with peace of mind.
