hi can anybody tell me where to get an uprated rear sock for a 04 rev 80

it depends what you mean by uprated. the 2 alternatives were a longer standard shock or a recon rev3 shock which did require a little bit of modifiction to the swinging arm to fit. it depends on how heavy the kid and what the limitation is of the present shock. both types were available direct from Lampkins though neither way especially cheap. the longer shock gave more travel , but the rev3 gave more adjustment providing the kid was both heavy and tall enough as the seat height rose a lot. Hope this helps.
