First thing I would like to say is thank you Megan and Nick at Top Dog Heavy Equipment Parts.

I must admit I am a person who reads reviews but never have really left to many reviews, this Company definitely deserves to be told about to people looking for heavy equipment parts I purchased excavator tracks through them the communication was good from beginning to end was updated several times on the order and shipping I do recommend Top Dog Heavy Equipment Parts, great online experience for a guy in the middle of nowhere on the Oregon coast.


Thanks Top Dog

Good information on selecting product, knowledgeable staff, follow up by Owner and Salesman (Nick) to make sure product was right and offer any assistance needed. Also, didn't have to wait for product to be available. It came as soon as it could be shipped. Price was also comparable and cheaper than others.

These guys are top notch. They can find any part for our fleet of heavy equipment, prices are good and they ship quickly. I text them a part number and they source it same day and ship it. Usually gets to us within 2 days, impressive operation with great customer service. This is a well run company through and through.

TopDog Heavy Equipment Parts is my new favorite place to get my parts. They are extremely responsive and fair on price. My most recent purchase was a swing motor for my Caterpillar 312 excavator. They found me a rebuilt one that works perfectly.

Give them a try - you'll like them! Thanks TDHEP!
