i believe 442 had one shortened by gt thunder, and prolly cost more to have the bottom eye removed and shaft re-threaded, than what the shock cost to begin with, and this shock, as it is, will have your blaster sittin like a 1983 camaro from the local trailer park, all jacked up on airshocks
they are not as compatable as the 400ex, 450r, z400 ect, ect
id pass and wait on a good priced 400ex
