Smith's Diesel Performance Introduce
For owners of heavy-duty diesel trucks in South Lebanon, Ohio, and the surrounding regions, Smith's Diesel Performance has established itself as a highly reputable and trusted service provider. Located at 201 S Mary Ellen St, South Lebanon, OH 45065, USA, this specialized establishment operates within the "Auto Repair Stations" platform category, with a clear focus on the intricate needs of diesel-powered vehicles, particularly heavy-duty trucks.
Unlike general auto repair shops that cater to a wide array of vehicles and issues, Smith's Diesel Performance distinguishes itself through its dedicated expertise in diesel engines and related systems. This specialization is crucial given the complexity and unique requirements of modern diesel trucks, from their fuel systems and emissions controls to their robust drivetrains and performance tuning capabilities.
The environment at Smith's Diesel Performance is clearly geared towards accommodating heavy-duty vehicles, implying larger bays, specialized lifting equipment, and diagnostic tools specific to diesel engines. A key characteristic of their operation, heavily emphasized by customer reviews, is their commitment to transparent and consistent communication. Nate, the lead mechanic, is praised for taking "the extra time to communicate with you throughout the process" and even sending "photos as the work progresses." This proactive approach to communication builds immense trust and keeps customers informed, alleviating the anxiety often associated with complex vehicle repairs. The shop's commitment to expediting services, even when faced with unforeseen challenges like needing machine services, further highlights an organized and customer-centric approach to their operational environment.
Smith's Diesel Performance offers a comprehensive range of services tailored specifically for heavy-duty diesel trucks. The customer reviews provide excellent insights into their capabilities:
- Advanced Diagnostics: The ability to diagnose complex issues, as evidenced by resolving a "no start condition" that escalated to an engine rebuild. This indicates a thorough and systematic approach to troubleshooting.
- Engine Repair and Rebuilds: Nate's expertise extends to major engine work, including a full rebuild necessitated by a defect in a cylinder head. This showcases their capacity for intricate and demanding mechanical repairs.
- Performance Enhancements and Modifications: Specific services mentioned include the installation of a CCV (Crankcase Ventilation) delete and a coolant bypass system. These are common modifications sought by diesel truck owners to improve performance, longevity, or address known issues.
- Component Replacement and Repair: Examples include installing a "new water pump" and repairing a "leaking front main oil seal" on a 2014 Ram 3500. This indicates proficiency in standard component repairs vital for engine health.
- Leak Detection and Resolution: The prompt response to a "major oil leak" after initial service, including towing the truck back and diligently finding the root cause, underscores their commitment to resolving issues completely and ensuring a leak-free operation.
- General Diesel Truck Maintenance and Service: While not explicitly detailed, their broad expertise implies they handle routine maintenance tasks, fluid changes, and inspections specific to diesel truck specifications.
The phone numbers, (513) 283-7117 and +1 513-283-7117, are available for heavy-duty truck owners to schedule appointments or inquire about specialized diesel services. Given the complexity of diesel repairs, making an appointment is highly recommended, as suggested by one customer.

- Unwavering Integrity and Honesty: Customers consistently praise Nate's integrity and straightforward approach. He discusses options, keeps customers informed, and avoids unnecessary work, building a strong foundation of trust.
- Exceptional Reliability and Accountability: This is perhaps their most distinguishing feature. Nate "stands firmly behind his work, and he backs it up with action." The dramatic example of him towing a truck back within an hour to address a post-repair oil leak, and then diligently fixing it, exemplifies an extraordinary commitment to ensuring the job is done right and the customer is completely satisfied and safe.
- Proactive Communication: The regular updates, including photos of work in progress, are a significant differentiator, keeping customers engaged and confident throughout the repair process.
- Expert Knowledge and Professionalism: Nate is described as a "great mechanic" who is "very professional and personable." This combination of technical skill and excellent interpersonal skills makes the repair experience much more pleasant.

I highly recommend making an appointment with Nate at Smith's Diesel Performance for your heavy-duty diesel truck. Nate is a great mechanic who takes the extra time to communicate with you throughout the process and he even sends photos as the work progresses. He installed a CCV delete, coolant bypass system, new water pump, and repaired a leaking front main oil seal on my 2014 Ram 3500. The work was completed on time and on budget. I greatly appreciate his integrity and willingness to help out. Nate went above and beyond to make sure I was happy, safe, and taken care of after my recent work at his shop. You will not find a more reliable mechanic who stands firmly behind his work, and he backs it up with action. Thanks Nate...now let's roll some coal!

I can't say enough good things about Nate and his team. Very professional and personable. I dropped my truck off for a no start condition. That escalated to a rebuild due to a defect in one of the cylinder heads and the subsequent damage it caused. Nate went over my options with me and kept me well informed on his progress. And even though there were some bumps in the road that were beyond his control, he expedited machine services to get my truck back to me as quickly as possible. His dedication to service didn't stop there. After receiving my truck it developed a major oil leak. Nate had it towed back to his shop in less than an hour! He and his team worked diligently to figure out the root cause then went above and beyond to make sure their repair fixed the issue and that it wouldn't happen again. Nate and team have definitely earned a life long customer.

“Smith’s Diesel Performance is hands down the best shop for diesel repairs and upgrades! The team is extremely knowledgeable, professional, and honest about their work. They took the time to explain everything to my buddy Eli and made sure his truck was running at peak performance. The quality of their work is top-notch, and their customer service is excellent. If you need repairs, tuning, or performance upgrades, this is the place to go. Highly recommend!”
