USE: 0130-3012 Qty (3)
The supplier has changed to a different color block, beige, with slightly different geometry. It has tiny wings at the sides that are supposed to help reduce noise at idle. It is always possible to replace just one block but it is not a good idea for 2 reasons:
1. The weight of the block is not exactly the same, so it might create an unbalance issue.
2. Since all 3 blocks wear together in the product, it is always better to change all 3 at the same time to ensure good performance.
