10" rear drums, V6 and turbo applications
used stronger third member with larger bearings and bigger third member,
coil sprung 4Runner axles are 1/2" wider than pickup axles, factory
4.88s available in vehicles equipped with automatic transmissions starting
in 1992, but the pinion is moved closer to the ring gear than on all the
other 3rds. This makes it so they can use a standard thickness ring gear
instead of an extra thick one. This "thin" 4.88 gear is only made by Toyotas.

Used on solid axle trucks. Displays quirky
steering characteristics when used in lifted applications. J-arm and drag
link are prone to breakage in extreme applications.

Used on IFS trucks but ideal for crossover
steering on solid axle equipped trucks.
