Toyota 4.30 Diffs w/ LSD or LOCKERS for front an rear axle

Skip to second post for locker talk

Yes, I'm installing 4.30's with a limited slip diff, my rear gears and traction in one tidy package.... I can hear it already though, why o' why would you even consider a LSD? Well, Toyota produces a nice tunable(!) clutch pack type LSD that IMO will benefit a vehicle like the 200 Series in far more situations on road and off, than a locker will. With that said, in a perfect world I'd have a LSD combined with a factory E locker for the 1% of the time it would work better, but we'll cross that bridge when we get there. A properly tuned LSD with A-Trac on top of it will perform most of the duties a locker will. All with nothing to switch, no wires or air hoses to get torn off, no buzzy compressor, no o-rings to fail. The nitty gritty of this is that the complete new 4.30 LSD 3rd member from a 1998 100 Series supercedes out to the current 9.5 diff. That gives it the pinion size used on the 200 Series. So 4.30 gears and a LSD with no down grade in the pinion spline count/diameter is the order of the day... no gear set up, no pulling bearings or other BS, just an easy diff swap. Pics when it arrives.

$1800 will put one in your hands, part # 41110-60A60. Add up an ARB, compressor, factory gears (or aftermarket for that matter), all bearings/shims, plus the install, and $1800 is a deal.

Front 4.30 differentials are plentiful and cheap.

Toyota has also superceded the 100 Series factory E-locker to the current 41110-60A90 E-locker. With a factory or custom passenger axle shaft, and some minor housing mods, we should be able to drop one of these in. The price of the unit is a bit better, about $1350, but the extras will run it past the LSD price.

I'll talk about a front E locker shortly.
 
I'm referring to Toyota's factory lockers.
