I have a 1995 F350 that I am modding out. I want to improve the steering and one component I am focusing on is the stick gear box. Is there and aftermarket alternative that will give me years of trouble free reliability like my stock one? Or is there a way to improve the one I have. I thought I read some where there are some simple mods that can be done to mine. I would like something with a tighter gearing and can handle the bigger tires. Any ideas?
