For information only.
4.56 and 4.10 are not taller gears than 3.55 gears. They are lower gears
than the 3.55. Lower gears are higher numerically; they provide more of a
mechanical advantage and 'cause' the engint to spin more rpm per mph than
taller gears. Taller gears are lower numerically; they provide less
mechanical advantage and 'cause' the engine to turn less rpm per mph
than lower gears. Hence the 4.10:1 gears are taller than the 4.56:1 gears,
but lower than 3.55:1 gears.
A gear ratio is the number of teeth on the driven gear (ring) divided
by the number of teeth on the drive gear (pinion). E.G. if the ring
rear has 37 teeth and the pinion gear has 9 teeth, the ratio is 4.11:1
That means that every one turn of the ring gear, the pinion will turn
Tall gears (numerically lower) are also referred to as high gears, shallow
gears, fast-ratio gears, less gear or loose gears.
Low gears (numerically higher) are also called short gears, deep gears,
show-ratio gears, stoplight gears, more gear and tight gears.
