Just want to know the basics. How much should I expect to spend on them, where's a good place to buy them from, and what do I need to do to install them? I looked for a diy but there isn't one so if someone could give a brief description of how to install 4.10 gears that'd be great. Trying to figure out what I want to do to my truck over the next two months and I'm leaning on the fastman and the 4.10 gears.

 

4.10 gears arent cheep unless you do it yourself. Iv been quoted 900-1300 for gear INSTALLS, thats after I bought the gears. I forget if I saw you had a 4x4 or not, but if it is, expect to pay that, and again. Front and rear have to be the same, otherwise your not going to be able to use your 4x. I suggest longtube headers after the fastman.
