You may want to consider upgrading to a 3 party. Might be blasphemy to some, but I was going through linkage rods at least once a year with the stock linkage on my dw 9000 pedals. Not completely breaking, but warping or bending enough to make the lag on the left foot too uncomfortable. Anyway, found these Trick Drums Linkage Rods that are designed specifically to work on specific brands. I've had these for well over 5 years (maybe more?) with no issues. Also way smoother than any stock linkage rods of any low to mid range model double bass pedals
