What is the primary function of load leveling in towing?

The primary function of load leveling in towing is to distribute the weight of the trailer across multiple axles. When a vehicle tows a trailer, the added weight can shift the vehicle's center of gravity and alter the distribution of weight on its axles. Load leveling systems, which may include adjustable air springs or weight distribution hitches, are designed to counteract this shift. By redistributing the weight, these systems help maintain a level stance for both the towing vehicle and the trailer, which enhances stability, braking effectiveness, tire wear, and overall handling during towing.

This function is critical for safety while towing because an unbalanced load can lead to difficult driving conditions or even accidents. With proper weight distribution, the vehicle's suspension works more efficiently, resulting in better control and a smoother ride for both the vehicle and the trailer.
