About Us

When your livelihood depends on a semi-truck, you need a repair shop that understands how much downtime can cost. S&V Diesel Repair is a family-owned heavy-duty repair shop in Harahan, Louisiana, dedicated exclusively to Class 7 and Class 8 trucks. From our shop at 5712 Susitna Drive, we serve owner-operators, fleet managers, and commercial drivers who need knowledgeable service for the trucks that keep their businesses moving.

S&V Diesel Repair officially opened in September 2024, but our experience goes back much further. Owners Vincent Bobzin and Steven Larousse spent more than 20 years working for the company that previously operated the shop. When the former owners retired, they took the opportunity to purchase the business and continue serving the customers and trucks he had already worked with for decades. With approximately 30 years in the diesel repair industry, Vincent and Steven bring a hands-on background as a diesel mechanic and a practical understanding of heavy-duty truck systems.

Specialists in Semi-Truck Engine Repair and Rebuilding

We do not divide our attention between passenger vehicles and commercial trucks. Our team works exclusively on Class 7 and Class 8 18-wheelers, allowing us to focus our equipment, parts, and experience on the needs of heavy-duty diesel vehicles. We service major truck makes including Freightliner, Peterbilt, Kenworth, International, Volvo, Mack, and Western Star.

Engine repair and rebuilding are at the center of what we do. We specialize in Cummins and CAT engines. 

Our capabilities also include Cummins fuel pump rebuilds, air conditioning service, and flywheel resurfacing. Having specialized equipment in-house helps us complete certain truck repairs without sending every component to an outside provider. 

Specialty Truck Repair Shop That Stands Behind Its Work

At S&V Diesel Repair, customers come first. We want to become a trusted heavy-duty repair resource for Harahan, the New Orleans area, and surrounding communities by providing excellent service at a fair price. We believe drivers deserve clear information about what their truck needs, practical repair recommendations, and workmanship they can feel confident putting back on the road.

Qualifying repairs may be covered by a six-month warranty. Because coverage can vary by repair, parts, and other conditions, please ask our team to confirm the current warranty details that apply to your service.
