Preventive Services for Commercial Trucks & Trailers

Proactive Care for Peak Performance – STTR, Inc.

At Sound Truck & Trailer Repair (STTR, Inc.), we believe the best repair is the one you never need. Our Preventive Services are built around this principle—helping owner-operators and fleet managers avoid breakdowns, reduce emergency repair costs, and keep trucks and trailers performing at their best.

Preventive care is not just a service — it’s a strategy.

What Is Preventive Service?

Preventive services go beyond routine maintenance. This proactive approach is scheduled based on mileage, hours, or usage conditions, and is designed to:

• Reduce downtime

• Avoid costly repairs

• Extend vehicle lifespan

• Ensure DOT compliance

• Improve safety and fuel efficiency

Customized Preventive Service Plans

Every operation is different. That’s why STTR works with you to create a tailored preventive maintenance plan based on your equipment, routes, and service intervals.

Our preventive service programs include:

• Full Multi-Point Inspections

• Scheduled Fluid & Filter Changes

• Wear Component Monitoring (brakes, belts, hoses)

• Tire Rotation & Pressure Checks

• Coolant, Transmission, and Differential Flush Intervals

• Battery & Charging System Health Checks

• Safety Lighting & Air System Reviews

• DOT Pre-Inspection Readiness Services

We track your preventive service history and recommend timely interventions—so you’re never guessing when it’s time for service.

Ideal for Solo Operators & Fleet Managers

Whether you’re operating one truck or managing a fleet, STTR’s preventive approach helps you:

• Avoid roadside emergencies

• Meet DOT standards before inspections

• Maximize uptime and vehicle ROI

📆 Preventive services are available Monday through Friday, 8:00 AM to 5:00 PM, at our Pacific, WA facility. We’ll help you build a schedule that works around your runs—not against them.

Why Preventive Over Reactive?

💡 Reactive repairs cost more in parts, labor, and lost time.
💡 Preventive service saves money, boosts safety, and keeps your rig running longer.
