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!

We ordered tracks and a thumb bucket. Their customer service was top notch! They followed thru, called back, made sure the order was correct and they even called after we received the parts to make sure everything was ok. Packaging was first class and shipping was fast.

We would highly recommend this company for your parts needs.
