    Default Rear End Mod

    Why don't guys do more changing of rear end gearing?

    We hear much about S/C & more, but little about changing rear ends.

    Is it because there are more changes that can be made and are ongoing such as tuning, headers, & more once a S/C is added? And similarly, are there more possibilities for additional incremental changes when changing throttle bodies, intake & exhaust manifolds, valves & springs, and other component parts?

    Is it because we can't show a 4.11 rear, whereas we can show a S/C, intake, headers, and other stuff?

    With six gear transmissions that include two over-drive gears, it seems a rear end gear change would be a performance upgrade with little negative impact upon mundane aspects such as fuel mileage and engine wear.

    I'm with you one this one, gearing is one of the major things that should be done to fit the driver, mods and use. But hey what they don't know will hurt them when you pull on side of them.

    If the rumored "10,000 rpm" turbo V-8 comes true, then you might see shorter gears. Right now, you just end up with add'l engine heat, more stress on the driveline, worse gas mileage and your engine is worn out sooner...

    such a deal!
