OCD Performance & Offroad LLC

DJ and staff were absolutely amazing. I am a Hotshot driver and I broke down on a Saturday about 3 miles from their shop. I had just had a complete fuel system done on my 2019 powerstroke from another shop and the injector return fuel line separated. I contacted them as soon as they opened on Monday and they put my truck in front of the line and ordered tge new line and got it Installed on Tuesday. Truck was running great. I hooked up tge loaded trailer and it was running great until I was climbing a hill and the new line separated. They came and rescued me and spent all day Wednesday diagnosing why were having same issue. Found 2 injectors returning very excessive fuel. They worked intil 11:30 ish pm to get it fixed. I was on the road with a truck running like brand new on Thursday. Great people and incredible customer service and compassion!!
I highly recommend them. I can’t have enough great things to say.

A really great down-to-earth company. They go the extra to help Fix any problems with your vehicle.

DJ and Rick helped me with a pretty serious overhaul on my LML long block. Not only did they give me several options to choose from they went with a company they had not done business with yet and helped me get the engine I wanted. I’ve got little more than 2000 miles and I couldn’t be happier. They have my business and loyalty from here on out. I’ll be buying you guys lunch next week.

These guys did a great job on my Ram. Installed Amp power running boards, and new cat back high performance exhaust,sounds awesome .
Great job guys!!!

I brought my 2013 F450 in with a check engine light. They did an accurate assessment (rodent damage to the wiring/bad ECM). Fixed the truck on time and for the estimate quoted. Also purchased an H&S intercooler upgrade pipe and S&B cold air intake. The truck has never run better!! Was getting 10.4 mpg loaded or empty, now getting 11.5 mpg pulling 10K and 13.7 empty. I won't hesitate to take my truck back to DJ and his team!

Great service! My truck was having problems as I was driving through town on vacation. We stopped by the shop where they gave us 20 minutes of their time to fix my problem and get me back on the road free of charge.

There are good people in this world, and you can find some of them here!

Had a failure on an early 2011 model 6.7 diesel with low miles on the truck. Had OCD Performance replace the engine with lots of upgrades to the motor , suspension, and braking system. The truck runs and rides awesome. Great to work with. Thanks

The best diesel, custom truck shop you’ll find!! Very knowledgeable staff that have the abilities to not only repair your vehicle, but can also take your truck to the level above the rest. From routine maintenance to lift kits and custom wheels they can do it all!

Took my 07 Cummins in for a rough start issue. Ended up having Dj do some performance upgrades for a better tow setup on my truck. Asked Dj what he recommended and he knew exactly the perfect setup. He knocked the upgrades out of the park in a timely fassion with excellent communication and customer service. Will definitely be taking my truck back for any future upgrades!

Great guys, posted in a Facebook group saying about needed a part and they messaged me saying they had one in stock and overnighted it to me. Great guys highly recommend!

If I could give more stars I would! We live in a time we're its hard to find legit mechanics that we can trust and DJ goes above and beyond! Straight forward, doesnt try to get every penny out of you with things you don't need for your truck. He actually trys to save you money and does the work 100% legit while saving you $ no cut corners. He knows what he's doing and loves doing it. Stays to his word on time frame and definitely values his customers! HIGHLY recommend!

OCD is the best diesel performance shop in the STL area. They are very knowledgeable when it comes to diesels! I had the worse case CP4 failure and they knocked it out the park! They had the best pricing, excellent communication and just an overall great experience. Looking forward to working with them again!

I brought my 2006 f250 to DJ at ocd with concerns after seeing some white smoke coming from my exhaust. After he checked it out he informed me it was turbo related. Dj got the turbo swapped out with some upgrades and I couldn't have been more happy with the work and price. 10/10 would take my diesel here again.

I am from Wisconsin and got stranded in Pevely, MO on a trip with a horse trailer. we were stranded for hours and no one could help us or give us answers. We were lucky enough to have a guy pass us and give us DJ's number and he came within 30 minutes, and had us runing and on the road within and hour after 4 hours of sitting in the burger King parking lot. He is so knowledgeable and does an amazing job! We really would have been in trouble without him!

Highly Recommend! DJ & His Team Are Very Knowledgeable & Are Very Friendly! Thank You For Taking Care Of My Truck!

Great service and straight to the point! Gave them my build and budget, and these guys made my dream build come true!

Ocd knows their stuff and will never give up on your vehicle until it is fixed and fixed right the first time. Highly recommend contacting them for anything that has to do with an engine, performance, offroad, custom one off improvements.

DJ took great care of my truck and had a VERY fast turn around with great prices.
He answered all my questions and is a great guy.

I highly recommend you do business with them!

Very Very good work, wont be taking my truck to anyone/anywhere else. He is very knowledgeable and his work shows.

Quality service reliable
