Bought a complete fuel system, made a huge difference, just want to says thanks for a awesome system.

The diesel site company is hands down the best high quality parts money can buy! when u receive their products you will quickly noticed the high quality packaging! the instructions are fantastic and well written! the regulated return system I fantastic and my 2003 ford e350 4x4 van runs absolutely awesome after installing the new system! All my mods are from the diesel site ! I couldn't be happier! I own a performance shop in Pennsylvania and want people to know the Diesel site is a great high quality company!

I would really recommend this seller. With the coronavirus going around I needed my truck as a volunteer firefighter paramedic and they were very helpful in making that happen.

Customer service is amazing

This a great family owned and operated company! Bob, Todd, and Crystal were very helpful every step of the way. Made the trek down to have a new trans, tc, external trans filtration filtration system, tru-cool cooler, flex plate, and up-pipes installed. They got everything installed and I was back on the road in no time! I absolutely love their transmission it is night and day difference. Thank you again DS!! I highly recommend and will continue to use DS in the future!

From wicked wheel to legendary transmission love the products and customer service is always avalible to help with tech questions. Great company .highly recommended

I've ordered a bunch of diesel site products. I've always been very high quality. Anytime I've had a question about installation or an issue with one of my products the people at diesel site have always gotten it taken care of.

Had a great experience with DieselSite during a bad time. I was 300 miles from home and had an HPOP failure. Everyone I talked with at DieselSite were very helpful and got me my new pump quickly.

but they granted a full refund. i do hopw they will find a wheel that does fit and create a billet wheel to send me as I will purchase it

Great easy to use website and even greater products. You guys make some amazing products and deliver a customer support service that’s not found much anymore these days. Keep it up! Love supporting American Businesses. You guys help keep my truck doing what it was meant to do.

great

Had the parts I needed when I needed them at a good price with fast service

I had to replace my glow plugs on you 7.3 diesel. The staff is very helpful and knowledgeable. The parts work great

Great company quality parts

Parts showed up quick and ordering was easy. I really like the toolbox magnet that came with the order too 👍

really good CACC boots

Great products and customer service. I recommend Dieselsite for quite a few products and especially the coolest filters.

Great product

Helped firm up a lazy shifting rebuilt 4r100, it makes it feel like a new truck. Crisp, firm shifts and doesn’t hesitate to shift anymore. Recommend this VB for every 4r100 in stock or build form

I love this site.
