OEM parts aren’t always better. Many aftermarket semi truck parts are built by the same manufacturers, carry the same warranty, and sometimes outperform OEM components by fixing known design flaws. The real difference often comes down to branding, not quality.

Why Is My Semi Truck ABS Light On?
An illuminated ABS light on a semi truck means the anti-lock braking system has detected a fault and temporarily disabled itself. While your service brakes still work, ABS assistance is lost—reducing control during hard braking or low-traction conditions and potentially leading to DOT citations. The most common causes include dirty or misaligned wheel speed sensors, damaged wiring or connectors, blown ABS fuses, and trailer electrical issues at the 7-way plug or pigtail. Intermittent ABS lights usually point to wiring or connection problems that worsen over time. The correct fix starts with basic inspections and diagnostics to identify the root cause and safely restore full braking performance.

Fuel costs are one of the largest expenses for any fleet. This article breaks down how modern diesel trucks achieve better fuel efficiency through aerodynamics, transmissions, driving habits, and emissions-era engine technology.

Driving a heavy-duty truck with misaligned wheels puts safety, fuel economy, and tires at risk. This short guide breaks down the five telltale signs — uneven tire wear, pulling to one side, steering vibration, an off-center wheel, and squealing tires — so drivers and fleet managers can spot misalignment early and take action to avoid costly downtime and repairs.

When it comes to semi truck inspections, knowing where and how to get your vehicle inspected is crucial for staying safe and compliant on the road. Semi trucks face unique challenges due to their size, weight, and load demands, making regular DOT inspections essential. This guide covers key tips for local semi truck inspections, federal DOT inspection requirements, common safety checkpoints, and maintenance steps to keep your truck compliant, avoid violations, and ensure reliable performance.

The diesel particulate filter (DPF) plays a critical role in reducing harmful soot emissions from diesel engines — but over time, the filter can become clogged if the trapped soot isn’t removed. That’s where regeneration comes in. There are three common regeneration methods: passive regeneration, which naturally burns off soot during long highway drives when exhaust temperatures are high; active regeneration, where the engine’s control unit injects extra fuel to raise exhaust heat and burn off soot when regular driving isn’t enough; and manual (or forced) regeneration, a technician or driver-initiated cleaning for severely clogged filters. Understanding how each process works can help truck owners and drivers optimize DPF maintenance, prevent costly downtime, and stay compliant with emissions standards.

Poor truck handling isn’t just uncomfortable—it’s a safety risk. This guide breaks down the common causes of handling problems in medium- and heavy-duty trucks, including damaged shock absorbers, worn bushings, misalignment, seized brakes, and overheating power steering fluid. Each issue can affect stability, control, and tire wear, but regular maintenance and timely repairs can keep your truck road-ready.

Your turbocharger plays a critical role in your semi-truck’s performance. Off-brand options may save money upfront but often lead to poor fuel efficiency, breakdowns, and expensive repairs. A quality, name-brand turbo delivers reliable power, better fuel economy, and long-term value—keeping you on the road and out of the shop.
