This is what you expect from such a stellar company.....excellent prices, knowledgeable staff and great products. I have used them on various occasions and have no reservations in recommending them to my customers all around the world. There is no sale that is too big or too small that they do not dedicate their 100% attention to. Always looking forward to the next order as it is such a pleasure doing business with them.

In the industry since 1983 and have dealt with suppliers all over the country and can honestly say HD Kits has been the best supplier I have ever encountered. Due to superior customer service and in all my years dealing with Jose and HD Kits they have never not been able to supply what was requested. That is a rarity in this industry

We have been working with this company since 04/2013 and we have had nothing but success. The staff is knowledgeable and efficient and always seem happy to receive our call. As one of the largest independent Med/Heavy duty truck repair shops in S Florida, we must have a Vendor that covers ours and our customers needs. Heavy Duty Kits does just that.
