When temperatures drop and winter weather rolls in, your truck faces a whole new set of challenges. Cold air, icy roads, and shifting pressure can all affect performance—especially if you haul heavy loads or rely on a specialized suspension system.
To help you stay safe and keep your vehicle in top shape, RETRUE has put together this essential winter care guide for truck owners.
1. The Science of Cold Air: Managing PSI
It’s a simple rule of physics: as temperatures fall, so does air pressure. For every 10°C drop in temperature, your tires and air springs can lose significant pressure.
-
Beyond Tires: If you use air suspension bags, the cold air inside will contract, leading to a lower ride height and reduced load-carrying capability.
-
Trailer Stability: For those utilizing an air ride trailer suspension, maintaining balanced pressure is critical. Uneven air levels can cause "rear-end sag" or instability when navigating icy curves.
-
What to do: Check your pressure regularly in the morning when it’s coldest to ensure your air suspension in truck systems are at the manufacturer’s recommended PSI.
2. Guarding Your "Heart": Air Bag Compressor Maintenance
Your air bag compressor is the heart of your suspension system, and winter is its hardest season.
-
Fight the Freeze: Moisture is the enemy. Water vapor inside the system can freeze, blocking valves or damaging seals.
-
Keep it Running: Ensure your compressor is functioning correctly before the first deep freeze. If you hear unusual grinding or if it takes longer than usual to lift, there may be ice buildup or a minor leak caused by cold-contracted fittings.
-
Pro Tip: Periodically drain your air tanks to remove moisture, protecting your springs air from internal damage.
3. Maximum Support: The Role of Helper Springs
Winter hauling (like carrying salt, wood, or plowing gear) puts immense strain on your factory suspension.
-
Added Stability: Helper springs are vital during winter. They provide the extra support needed to prevent bottoming out on frozen, bumpy roads.
-
Leveling the Load: Using a RETRUE air suspension kit ensures your truck stays level, which is essential for maintaining steering control and braking efficiency on black ice.
4. Practical Winter Hacks for Truckers
Beyond the suspension, small details can make or break your morning:
-
Key Stuck in the Door? Freezing temps can cause door locks to contract. Don’t force the key! Use a hair dryer to warm the lock for 10–20 seconds, or slightly warm the key before inserting it.
-
Sluggish Brakes? It’s normal for brake pads and rotors to feel slow to respond on cold, frosty mornings. Gently tap the brakes a few times when you start driving to clear any frost and build up friction heat.
5. Battery Health: The Cold Start
Cold weather drains battery performance, especially on older units. A strong battery is essential for powering your air bag compressor and starting your engine in sub-zero temps. If your battery is more than 3 years old, have it tested before the first major snowstorm.
A Little Care Goes a Long Way
Winter doesn’t have to be hard on your truck. With a few simple habits—checking tire and airbag pressure, warming locks, and inspecting your compressor—you can drive safely and keep your vehicle in great condition throughout the season.
