had a buddy here at the track with the same servo with the stock bell crank and blew the servo. From what he told me he contacted one of the distributors here locally and they said the lowpro servo hasnt been holding up in offroad cars. He put a 1257 in and has had no problems, I'v also run a 1257 for the last 8 months or so with a glued servo saver and had no problems.
