Team Grid releases the ultimate tool for easy installation of shock rod end balls to shock shafts. The Team Grid Shock Shaft Tool makes it effortless to assemble hundreds of shock shafts without ever having to squeeze a pair of pliers. The Team Grid Shock Shaft Tool uses a clamping design, so that once it is clamped down on the shock shaft, it wont let go until you are ready to release it. Incorporating 3, 3.5 and 4mm holes, this tool will accommodate almost all of today’s shock shafts, especially the 4mm shock shafts which are the toughest to install ball ends as most builders already know. CNC machined from USA Grade aluminium and anodized for durability.
