As a local shop with decades of experience, our technicians understand the demands of towing places on your vehicle.

Trailer Hitch Services in Longmont, CO
A secure hitch is the foundation of safe towing. When mounting points, couplers, or receivers begin to wear, towing stability can decline. Our ASE-certified team provides thorough trailer hitch service designed to help your vehicle handle the load properly.
Professional Hitch Installation
A reliable connection starts with proper installation. We select hardware that suits your vehicle’s towing capacity and matches the equipment you plan to tow. Correct placement and secure fastening are crucial for safe operation, and our technicians install every component with precision so you can tow with confidence.
Trailer Hitch Maintenance Services
Regular attention helps prevent early wear. During trailer hitch maintenance, we inspect:
- Mounting bolts
- Receiver condition
- Coupler integrity
- Safety chain points
- Visible rust or structural wear
This service supports longevity, reduces the chance of binding or disconnecting, and keeps your towing setup stable during travel.
Trailer Hitch Coupler Maintenance
A worn or stiff coupler can cause issues during hookup, and poor performance may lead to trailer sway. Our technicians check latch mechanisms, lubrication points, and locking hardware. If the coupler shows signs of fatigue or deformation, we guide you through replacement options that fit your towing needs.
Trailer Hitch Receiver Maintenance
Receivers are constantly exposed to stress from load weight and road movement. During trailer hitch receiver maintenance, we examine the interior channel for wear, check the pin fitment, and assess structural condition. These steps help maintain a strong, reliable connection between your vehicle and trailer.
Trailer Wiring Services
Safe towing requires proper lighting and a strong electrical connection. If your trailer lights flicker, fail intermittently, or stop working completely, wiring problems are often the cause. Faulty wiring can lead to ticketing, miscommunication with other drivers, and increased risk in low-visibility conditions.
Complete Trailer Wiring Repair
Our technicians diagnose:
- Shorts and broken connections
- Corrosion in plugs or wiring bundles
- Faulty harnesses
- Incorrect or loose grounding
- Damaged light housings
We restore functionality using high-quality wiring components that stand up to daily use and harsh weather.
Trailer Wiring Installation
If you’ve purchased a new trailer or tow vehicle, you may need a fresh wiring setup. We install standard 4-pin and 7-pin connectors and verify compatibility with your vehicle’s lighting system. Once everything is connected, we test all signals to confirm that turn indicators, brake lights, and running lights perform as intended.
Tire Services for Towing Vehicles
Towing places added demands on your tires. The extra weight increases heat buildup, affects wear patterns, and influences how the vehicle handles. At Stonum Automotive, we offer a full range of tire services to keep your towing vehicle stable and road-ready.
Tire Inspection and Replacement
Worn or damaged tires reduce control, especially when pulling weight behind you. Our team checks tread depth, sidewalls, inflation, and overall condition. If replacement is needed, we help you choose tires suited for your driving habits, load requirements, and vehicle type.
Tire Rotation
Rotation helps distribute wear evenly. This is particularly important for vehicles that tow heavier loads, as front and rear tires often experience different stresses. Routine rotation helps improve tire longevity and supports more consistent handling.
Tire Balancing
Unbalanced tires can lead to vibrations, steering issues, and premature wear. Balancing ensures smooth performance and helps maintain stability, which is especially important when towing.
Signs You Need Trailer Hitch, Wiring, or Tire Service
If you’re unsure when to schedule service, look for these indicators:
Hitch or Coupler Issues
- Difficulty attaching the trailer
- Excessive movement at the connection point
- Rust around mounting bolts or the receiver

Any of these symptoms signal that service is needed to maintain safe operation. Our team is here to provide a full inspection and guide you through the next steps.
Why Towing Maintenance Matters
Towing requires your vehicle to perform under increased strain. Hitch connections bear weight and torque, wiring transmits vital safety signals, and tires handle additional load.
Regular attention reduces the risk of:
- Trailer sway
- Brake light or signal failure
- Tire blowouts
- Coupler or hitch hardware fatigue
- Unsafe towing conditions
With proper care, you support safer travel, protect your equipment, and limit unexpected breakdowns.
