Speedometer wont go over 50???

[600sprint97]

A couple weeks ago my speedometer went bad..
I drove about an hour out to the races and it worked fine.
On my way home it wouldnt go over 50???

Didnt think it was that big of a del till i got a speeding ticket the other day.

Anyone know why this would be happening?

So, agai going to the races last night and getting on the highway looked down at the dash and NONE of my guages work at all... the Tow/Haul button doesnt work either.. Radio and AC all work fine.

Anyone know whats causing this and how much its going to cost?

Seems like the races are bad luck for my truck...
