Great selection, super fast (free!) shipping They had a piston set I couldn't find anywhere else. Shipping was free and it arrived overnight! So pleased

Fantastic! My mechanic said my parts were all OEM . Love the check this part feature that allows me to be certain the part I order will fit my truck. My savings was over $200 cheaper than my Mechanic's price and my Mechanic stated they were OEM and came with more parts in the kits like all the grommets and gears he would usually have to get separately. My timing chain kit had Markings that ensure all 4 chains align perfectly. Very happy.

Garbage company Garbage company Trying to say, we order the incorrect parts when we’ve been in business for 15 years

Your customer service is great, but... Your customer service is great, but.. Unfortunately, your product, DNJ piston rings, did not adequately fit the DNJ piston. Specifically the 3 part oil rings. As such, I was forced to go with another vendor. I would also add the instructions are sparse.

Saw a notification if you order in 2… Saw a notification if you order in 2 hours it would be here next day placed my order got free shipping and ups truck was dropping off my order the next day. Flawless execution I will definitely use the site in the future!
