    speedometer and 33\'s

    How far off does a set of 33 inch Futura Dakotas change my speedometer from stock? I wanted to be sure i dont get pulled over and hassled. I havent been in the mood lately for any b/s.

    not much... maybe 5 mph at the most. I put lower gears (4.11's compared to the 3.73's) in my '89 and the speedo is pretty accurate up to 55 mph... the when the speedo says 85 it's really 76 or 77 mph. If you really want to fix it, go to a chevy dealer and get the next size speedo gear to go in the t-case... I know that they have about 7-10 different gears

    NEVER been stuck... *yet* (4wheeling)
