Black Series ALT 12V 240A, TOYOTA PRADO, HIACE, LC76/78/79 1GDFTV, 2GDFTV
CHARGES HARDER AT IDLE
Higher charge at lower RPM, so the gain shows up around camp rather than only at highway speed.
DIRECT REPLACEMENT FIT
Factory mounting location, 160mm spacing and a 17mm shaft. No brackets or spacers needed.
240A REPLACES 120A
Double the factory output, so a loaded touring system is no longer sitting at capacity.
OE INTERNALS THROUGHOUT
OE stator, rotor, regulator, rectifier and clutch pulley, in a black powder coated housing.
2 YEAR WARRANTY
2 years or 25,000km against defects in materials and workmanship, direct from the manufacturer.
The BKS-240TP is the Black Series 240A alternator for Toyota's 1GD-FTV and 2GD-FTV diesel engines, covering the Prado, the HiAce and the LandCruiser 76, 78 and 79 Series. It delivers 13.5V at 240A cold and 13.5V at 217A hot, which is roughly 120A more than the factory unit, and it makes that extra current available at lower engine speeds rather than only once you are up and moving. That matters most at idle and around camp, where a standard alternator has the least to give and your accessories are still drawing.
It is a direct replacement in the factory mounting location, with a 160mm centre to centre mount spacing, a 52mm mount leg ID and a 17mm shaft. The unit runs a 7PV clutch pulley at 65mm diameter, a rear entry regulator, and OE stator, rotor, regulator, rectifier and clutch pulley internals. The housing is black powder coated, so it looks like it belongs under the bonnet rather than like a reconditioned part.
Plan for the wiring before you order. A battery positive wiring upgrade is required with this alternator. Run 0 B&S cable from the alternator to the battery with a 250A mega fuse inline of the new B+ terminal. The factory cable was sized for the standard unit and will not safely carry 240A, and leaving it in place is the single most common reason a high-output alternator never delivers what it is rated for. We build complete kits that pair this exact alternator with a harness already built to that spec:
Toyota Prado 150 Series 1GD 240A Upgraded Alternator Kit →
This alternator plus the matching harness for the Prado 150.
LandCruiser 70 Series 1GD 2.8L 240A Upgraded Alternator Kit →
The same alternator with the harness cut for the 70 Series 2.8L.
Elevate Alternator Upgrade Wiring Kit, LC70 2.8L 1GD-FTV →
The harness on its own, if you already have the alternator.
One limitation to know before you buy: this alternator must not be connected directly to a lithium battery, and doing so voids the warranty. A DC to DC charger goes between the alternator and any LiFePO4 bank. Wired that way it works exactly as it should, and gives the charger far more current to draw on than a standard alternator ever could.

Connecting this alternator directly to a lithium battery voids the warranty. A DC to DC charger must be fitted between the alternator and any lithium bank.
