Yes at least it does on the TLBs (I havent reviewed the others). However I had a an engineer on the forums with a M59 consider the extra weight vs the rear downrigger cylinder and he felt like it would easily support the added weight, AND stabilize the machine more during BH use. He was correct, it worked out great. My dealer filled the rears and didnt feel like it would affect warranty at all. I guess if I break something we will find out if that is true!
