Ck your cassette to see which pill is in it assuming u are running a vector or impulse. If so they make a 0 through 1/4 pills. We run 0's and if we need to raise it up we flip a 1/16 pill upside down to raise the lr. Frame rail. Hope this helps.
Not real sure on what pills are in it , but I'll check. Running 3.5 and 4.5 on air on very low bite track, more sand than anything.
"Millenium's cassettes and hangers are not designed the same as Phantom's, and should NOT be setup in a similar fashion". Please explain, and it an 2012 Impulse.
