Technical Information about Suspension Parts

Heavy Duty Truck Suspension Parts are used to be cornering or lateral quickening causes the chassis to roll. Suspension Parts during a cornering steer, the weight apportionment of the entire truck changes and is transferred property around the four corners.

In a right-hand corner, the most weight is located on the left front wheel. If the truck is braking in the corner, even more weight is moved to the right front wheel.

Weight transfer is a good thing when it comes to generating clutch. But, weight transfer can cause the suspension parts to compress. When the suspension parts compresses, the suspension angles (camber and toe) exchange and alter the footprint of the tire. Some of the angle changes can help improve grasp, but past a certain point, they can subtract the contact repair of the tire.

Chassis roll is another factor in chassis dynamics. As a truck corners or speed up, the chassis or body will roll and compress the suspension parts. The amount of chassis roll is not only decided by the type of steer, but also by where the weight is in the truck along with how much the suspension compresses. Trucks with a higher center of gravitation will have more body roll, and under braking, will transfer more weight to the front tires.

Shock & Struts

Performance of shocks and struts, it is critical to understand compression and rebound. Increasing the compression setting of a shock or strut increases the amount of force necessary to compress the unit. Increasing the leaping setting increases the amount of force necessary to extend the unit. On some units, compression and leaping are tuned for low- and high-frequency suspension movements. Most non-adjustable performance shocks and struts will have more leaping when compared to the stock unit. This is controlled the spring and avoid undesirable weight transfer.

Setting an adjustable unit to the maximum settings for compression and leaping does not make for the best handling truck. Even though the shocks and struts are not physically connected, physics and several forces do connect them. When a shock is out of specification at one end, it will affect the weight transfer and handling at the other end or opposite corner. Both the race mechanic and engineer are trying to strike a balance between being “push” and being “loose.” They are also trying to make sure the settings are optimum for a kind of conditions and surfaces.

This impartiy can be experient if the truck has to do a panic stop and sudden lane change. When the weight loads the front tires, the rear spring enlarge, which makes the contact patch of the rear tire smaller. If the shock or strut is unable to control the leaping of the spring, additional weight is transferred to the front, which can cause the truck to nosedive even more.

During a panic stop, the trucks becomes unstable if it needs to swing to prohibit something in its path.
