In addition they doubled the variety of anti-rotation pins to maintain the saddle pointing the place it ought to, decreasing rotational play with out including friction. Two extra outsized polymer pins assist additional. Lastly, the seals are all new with an improved collar and SKF wiper seal to maintain crud out and lubrication in.
