What do you think about this product?



Does this kit include the newly manufactured parts discussed in the technical "not recall" bulletin? I have a 180 EXP with a pre "1" production code.


Is this a tooless install on the updated 240 EXP? Have read some conflicting information that you need a special tool for the star ratchet.


will this work with the 370 hub as well?

This upgrade kit will work just fine with your 370 hub!
