grizzly 600 rear shock

so i found this gabriel overload shock for an old ford and its suppose to add 550 pounds of capacity to a truck.. have any of yall used a shock like this on an atv? its the same length as my stock shock and same mounts too.. it bolts right on.. i can buy two of these shocks new for $60 lol the factory shock is like $400 and not available… what yall think?
