Pictures above show excessive wear on the inner race or knuckle as well as on the journals of the outer casing. Inferior quality cv joints also wear prematurely in this manner due to poor quality materials used on the outer casing, inner race and cage. To cut costs, the time spent on the heat treatment process is cut back on thus compromising the hardness and durability of the cv joint .

Below are pictures of a GSP cv joint (Left) and an inferior quality part (Right). The GSP cv joint goes through a medium-frequency heat treatment process after which it is subjected to a tempering furnace. The heat induction process is extremely thourough to ensure the correct hardness and even shows the induction marks burning through the casing. This makes for a long lasting durable cv joint.

The below picture on the left of a GSP cv joint shows the six journals on the interior part of the outer casing. The finish on these journals is extremely important as these are the contact points where the ball bearings run in. GSP cv joints are machined by a CNC grinding machine after which they go through several polishing stages to ensure a smooth, low friction surface. 

The picture on the right is of a inferior quality cv joint which clearly shows the lack of the polishing process on the journals. This in turn compromises the tolerance of the internal components and the overall quality of the cv joint.

GSP stands for quality. When your safety is in our hands, only the best will do!
