I don’t know the official name for what this may be, but i’ve been wondering lately what causes newer trucks to have that smooth ride feel where you don’t really feel the “grittiness” of the truck. I have an 05 Titan and i can hear and feel it when i drive, but newer trucks are smooth.
Is this from weather stripping? drive train? electronics? just curious.

Tldr: The smoothness of a truck’s ride depends on several factors:
* The type of suspension system. Independent suspension systems usually provide a smoother ride than dependent or semi-independent suspension systems.
* The tires. Larger tires with lower inflation pressure and softer rubber usually provide a smoother ride than smaller tires with higher inflation pressure and harder rubber.
* The drivetrain. A well-maintained and aligned drivetrain usually provides a smoother ride than a worn or damaged drivetrain.
* The road conditions. Smoother roads with less curves and slopes usually provide a smoother ride than rougher roads with more
**Suspension type**
The suspension system is composed of springs, shock absorbers, and links or arms that connect the wheels to the frame. The suspension system absorbs the shocks and vibrations from the road and keeps the wheels in contact with the ground. There are different types of suspension systems, such as dependent, semi-independent, and independent. Dependent suspension systems have a beam or axle that connects the left and right wheels, so they move together. Semi-independent suspension systems have a beam that twists as the wheels move, allowing some degree of independence. Independent suspension systems have no connection between the left and right wheels, so they move independently. Generally, independent suspension systems provide a smoother ride than dependent or semi-independent suspension systems, because they can adapt better to uneven terrain and reduce body roll. However, dependent or semi-independent suspension systems may be more durable and cheaper to manufacture.
**Tires**
The tires are the only part of the truck that touches the road, so they play a crucial role in the smoothness of the ride. The size, configuration, inflation pressure, tread pattern, and material of the tires can affect how they grip the road, how they respond to bumps and potholes, how they generate noise and vibration, and how they wear over time. Generally, larger tires with lower inflation pressure and softer rubber provide a smoother ride than smaller tires with higher inflation pressure and harder rubber, because they can conform better to the road surface and cushion the impacts. However, larger tires may also increase rolling resistance and fuel consumption, while lower inflation pressure may reduce tire life and handling stability. Additionally, single tires may provide a smoother ride than dual tires on some surfaces, because they have less contact area and less friction.
**Drivetrain**
The drivetrain is the system that transfers power from the engine to the wheels. It includes components such as the transmission, the differential, the driveshaft, and the axles. The drivetrain can affect the smoothness of the ride by generating noise and vibration, especially if it is not well-maintained or aligned. For example, a worn or damaged transmission may cause jerky shifts or slipping gears; a faulty differential may cause clunking or humming sounds; a bent or unbalanced driveshaft may cause shuddering or wobbling; and a loose or broken axle may cause clicking or grinding noises. These noises and vibrations can be transmitted to the cabin and make the ride less comfortable.
**Road conditions**
The road conditions are another factor that can affect the smoothness of the ride. Different types of roads have different levels of roughness, unevenness, curvature, slope, and traction. These factors can influence how much shock and vibration are generated by the tires and suspension system, as well as how much steering and braking are required by the driver. Generally, smoother roads with less curves and slopes provide a smoother ride than rougher roads with more curves and slopes. However, some roads may also have hazards such as potholes, cracks, debris, or water that can damage the tires or suspension system or cause skidding or hydroplaning.
