I am thinking on either changing ping/pinion to a ex. 3.77 OR an "overdrive" 5th gear. My goals are mainly to get the rpm lower at cruising speed and also a higher topspeed.
I have tried to email RBT, but it comes back as not able to email them. Any thoughts or suggestions on where to get the parts? Are RBT still in business or does anyone have a better way to contact them?
Price difference for a 5th gear and ring/pinion? Thoughts?
