'98+ Dakotas don't use a speedo gear. They use a predetermined table in the
PCM to operate the speedo and ABS system effectively. The signal comes from
the Rear wheel speed sensor, mounted to the rear axle. The table in the PCM
only supports the factory options for tire sizes. Therefore, the biggest you
can go and still have the PCM, speedo, and ABS operating properly would be a
31x10.5x15 or a 16" equivalent. HTH,

I'm thinking about putting some larger tires on my Dak. Where is the speedo
gear at on my truck? I am wanting to put a different gear in so the speedo
stays correct. are there any problems I should watch for?
