When our Cat 320 swing bearing went out, we needed parts quickly. Ordered on Thursday, and installed it on Monday. The part was the perfect fit, and was working better than the original part. Two months later and still zero issues.

As a small operator, it is hard to afford dealer pricing. These aftermarket bucket teeth, perform just as good as OEM bucket teeth, at half the price. 300 work hours in, and the aftermarket teeth are barely worn.

Our Hitachi EX3600 hydraulic cylinders are abused every day. We switched out to these replacement heavy-duty cylinders last quarter—we are getting 30% better durability so far, and no leaks.

My John Deere 310's final drive was gone. 3 days later I was back to digging with the purchased rebuilt final drive. It has been operating smoothly and without strange noises. Just solid performance.
