No spam, no obligation. We only use your info to price your generator.

Why Caterpillar Gensets Command Premium Offers

Caterpillar's dealer network spans nearly every country on the planet, which means a used CAT generator can be serviced, parted, and rebuilt almost anywhere it lands. That global support network is why 3500-series units from the 1990s still trade actively today, and why export buyers compete hard for North American CAT iron. When we price your unit, that worldwide demand is baked into the offer.

We purchase every Caterpillar generator family: the legacy 3406, 3408, and 3412 packages; the big-bore 3508, 3512, and 3516 machines that anchor hospitals and data centers; modern C9 through C32 ACERT units; G3500-series natural gas engines; and XQ-series mobile rental units from XQ30 to XQ2000. Olympian-branded small gensets qualify as well.

Strong Resale Curve

CAT depreciates slower than any competing brand — your unit is worth more than you think.

Export Demand

Overseas buyers compete for 3500-series and C-series units, lifting domestic offers.

Rebuild Economics

Multiple-rebuild engine platforms mean even tired cores carry real money.

Reading Your CAT Nameplate

Everything we need is on two tags: the generator set nameplate (model, kW, voltage, serial) and the engine information plate (engine model and arrangement number). Text photos of both, plus the hour meter, to 954-740-1983 and we'll match your serial against current market comps. Offers on common CAT models typically go out the same business day, and rigging and freight are on us wherever the unit sits — all 50 states.

Caterpillar Seller FAQs

Which CAT generator models bring the strongest offers?

The 3512 and 3516 series lead the market, followed by C15/C18/C27/C32 packages and the older 3406/3412 workhorses. XQ-series rental units also stay in constant demand. Big-bore iron with documented hours tops every list.

My CAT unit needs an overhaul. Do you still want it?

Yes. Caterpillar engines are the most rebuilt engines on earth, and a 3512 core has real value even with a spun bearing or scored liner. We price rebuildable units on core value plus the generator end, not scrap weight.

Does a CAT service history from the dealer increase my offer?

Meaningfully. Dealer PM records, oil sample (S·O·S) history, and load-bank reports let buyers underwrite condition with confidence, and that certainty flows straight back into what we can pay you.
