This set supplies 12 plastic ball ends intended as replacement parts for the GPM Racing TRX4160A assembly used on select TRAXXAS TRX4 models. They are produced as RC-scale components and are specified by the supplier as replacements for GPM Racing #TRX4160A only, not for original manufacturer parts.
Use these ball ends where the TRX4160A assembly locates ball joint connections; they restore articulation at linkage points and allow adjustment of steering and suspension geometry without replacing the entire linkage. The supplied quantity covers multiple linkage positions or a full axle service on a crawler setup.
Installation notes: remove the worn ball ends from the TRX4160A sockets, press or seat the replacement ball ends into the same positions, and verify free articulation and a secure fit. Inspect for play after first runs and replace any unit that shows excessive wear.
