Gears gears gears...
 

Everyone is talking about how great a new set of gears can be. But what is involved with installing a new set? Is it a DIY? Is it easy to mess up the differential? What about calibrating the speedometer afterwards? Also what kind of a gas mileage hit would you expect going from stock to say, 4:10s?

Lets Say You Got A Ten Speed And Your Stock Gear Is Like The Hard Gear An A 3.73 ,4.10 ,ect Is Like The Easy Gear ,...........an Imagine Your Legs Is The Motor Thats The Pros An Cons Of Having A Gear You Have A Lot Of Acceleration But At The Cost Of Quicker Shifts An Higher Rpms On Freeway Rides An You Will Lose Atlease 4 Mpg With 4.10;s Depending On What Gears You Started With......an Its Not Hard To Do Your Self If You Can Take It Off You Can Put It Back On Or Shell Out Bout 300 Bux For Some One Else To Do It But If You Do It You'll No Its Done Right............4.10's For Auto An 3.73's 5 Speed For Daily Drivers Like Mine................

in general for a daily driver, 3.73's are good w/ stick, 4.10's w/ automatics. as for gas mileage, you highway MPG will go down a little as you will be cruising at higher rpm's. as for around town, if you don't mash the gas on every light and let the torque push you along, you may not see any decrease in city MPG.

as for installation, unless you are fairly skilled in rears, i would consider having a good shop install it as a sub-par install will lead to rear chatter and headaches

I agree with 83 right up until the last sentence. I have 4.30's in mine, 5 speed Tremec. I think the OD in the 5 speeds let's you get away with more gear. I ran 4.10's in her for 2 years, and had absolutely NO issues on the freeway.

Click on the "analyzer" button in here, there's an awesome calculator for figuring out engine speed/car speed/rear gears. You'll be surprised how steep of a gear you can get away with.

Don't Fear The Gear! ;)

I would let a shop do the install....just my .02.
