I think I am gonna go with the 4.88's. I'm just waiting on an email from Randys on price and shipping. In you opinion is there anything else I should purchase along with the gear and spline? All the other stuff the rep was quoting, I had never heard of before and that total was getting pretty expensive.
Is your truck a 4X4? If so you will need to change both front and rear differential gear sets to keep the ability to use the 4X4 function.
Changing the gears from 3.73 to 4.88 on my EX was the single biggest towing performance mod I have done. We tow an 11,000 lb TT and get between 8 and 9.25 MPG now, with the a cory gears we pulled a 9,500lb TH and could only squeeze out 6.5 to 7 MPG due to all the downshifting needed, now we stay in OD almost all the time.

The guys at Randy's will be able to tell you everything you will need to do the regearing. I'm pretty sure you will need everything the guys at Randy's are quoting you. There is substantially more than just the ring and pinion sets but I can't remember everything now since it's been 3 years since I did the regearing.
FYI, there is a fairly extensive and detailed break in procedure that needs to be followed after the new gears are installed. It is very important to follow the procedure closely.
Good luck and let us know how everything goes and how your truck responds to the lower gears.
