The LVACODV Trailer Tandem Slide Stopper is designed for use with semi truck tandem axle systems. It is constructed from cold rolled steel with zinc plating for corrosion resistance in trailer applications. This tandem slider stop lock functions as a locking pin tandem stop that inserts into the slider rail to help maintain tandem axle position after adjustment. The component is compatible with standard semi truck trailer slider systems and includes an ergonomic handle for insertion and removal. The Trailer Tandem Slide Stopper is intended for operators who adjust axle spacing to meet weight regulations and helps reduce unintended axle movement during transit.
