anybody know what speedo gears to use? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

into69z · 05-13-2010, 08:51 PM

I need your help,again. I need to fix the speedo error I have caused. I installed an 86 3/4 rear with 3:23 gears hooked up to a turbo 400. I have 2008 hd rims(16's) and 245/75r tires(about 28.5"). Does anyone have the correct trans/speedo gears numbers/colors I need to fix? At 40 on the speedo, I am going about 55 or so...Help anyone?...
