Proprietary Process
Products (cores) are returned to us from the field and are disassembled, losing their original identity. Each part then goes through a cleaning process and strict inspection to determine if it can be effectively salvaged. Those accepted are remanufactured using proprietary techniques and are updated to include the latest advancements.

High Standards
Many can claim to have quality remanufactured products but we’re ensuring every one we sell meets or exceeds Cat new parts standards. We measure, weigh and meticulously inspect each one.

Cost Savings
They’re good-as-new Cat products sold at a fraction of the new part cost. But how? Because we remanufacture the high-quality materials we require for our parts, we eliminate substantial costs — it’s savings we’re passing on to you.

Core Returns
Return your old product (core) to your Cat dealer and they’ll give you core credit based on our core acceptance standards. Your core credit goes toward the purchase of your next Reman part. Remember to follow our tips to ensure you get your full core credit.

Genuine Parts
We only remanufacture genuine Cat parts in acceptable condition because we don’t want to sacrifice quality for cost savings — and we know, neither do you.

Our new parts come with a one-year warranty — and so do our Reman parts.

Greater Sustainability
We’re reducing, reusing, recycling and reclaiming materials that once went into a landfill. And we use significantly fewer resources remanufacturing a part than we would building a new one.

Ongoing Support
Our dealer network spans 1,600 locations across the globe so there’s always one near you. They’re your source for Reman products and power system maintenance.
