Changing gears are often overlooked and offer an economic solution to acceleration. With 33's have you considered 4.56?

I have an excel spread sheet that gives engine RPM for different size tires/different rear axle ratios/and final drive transmission ratios. All you do is enter in the information and it calculates the engine RPM. I am new to this forum so I don't know how to get it to you without an e-mail.

I have a 2000 Gmc Sierra 4.8 and I want to get a posi-unit. maybe a eaton with 373 gears. but i really dont know alot about them besides that both wheel spin and the truck gets a good take off with good traction. Could anyone give me advice on what to look for when buying one and what would be a good price to have on installed. I asked a shop and they gave me the price of $1100 Installed. its an Eaton Differential, bearings, and 373 gears and the instalation. I live in Southwest Detroit, Michigan where here chevy trucks are popular and gettin them down to 11's is everyones goal. my truck is stock and it just has a k&n. my email is Juanelo_Irreziztible2008yahoo.com if any wants to write me on there. thanks

I have noticed latley that my rear diff will "lock" up when making turns and it sounds and feels like I am draggin the outside rear tire. This mainly happens after a fast start. I just changed the diff fluid 2 weeks ago nad inspected the oild fluid and didnt find any shavings. This is an itermittent problem. Any ideas? It is the G80 rear end too.
