Not sure where to post this one.
With a mph gauge that reads to 100 will going past this speed hurt anything and if so are there any aftermarket products out there that will change this.

 

well ive gone past 100 and ive had alot of vibration...upgrading to a big driveshaft would help prevent some probs.

 

I've gone past mine a buch. It hasn't changed the accuracy yet. I don't think it'll hurt.

 

I don't think it will hurt anything.

 

well the reason i said the driveshaft is because i had the 4.5 and while going 110 or so...the rear main seal on the transmissioin came off with teh vibration. after time my the transfer case on my truck cracked. do to the vibration.
