These GPM aluminum ball ends are intended for the rear link bar of the AXIAL SCX6 Jeep JLU Wrangler and are built from 6061 T6 aluminum for improved durability and consistent fit. The adjustable threaded construction supports both clockwise and counterclockwise adjustment so link lengths can be dialed in accurately, aiding alignment and predictable articulation. Compared with original plastic ends, these aluminium units reduce the likelihood of failure and provide a longer lasting link solution.
