24 Volt HP Radiator Fan (16")
 
 
>>> PERFORMANCE NUMBERS <<<
>>> PERFORMANCE GRAPH <<<
Electric fans are ideal for O.E. replacement, supplemental or add-on cooling needs. As a primary cooling source electric 
fans provide economical replacement for failed OE parts, with a 5-10% increase in horsepower and fuel mileage when 
replacing belt-driven fan assemblies. As an add-on cooling source electric fans provide increased air conditioning 
performance due to constant airflow across the condenser, with additional cooling in heavy traffic or while towing, or 
driving off-road.
The 24 volt High-Performance 16" Radiator Fan is designed for military or ex-military vehicles 
with 24 volt electrical systems (Uni-Mog, Pinzgauer, HumVee, Land Rover, Volvo, Deuce & a half, etc.).
 Adjustable 24 volt thermostat available (see link below).

10 Amp DC-DC Voltage Converter

(click image for large view)
Our DC to DC converters now have an extended input range. Designed for use on 24-80 volt equipment to provide a regulated 13.8 VDC output. Our standard (SD) DC-DC Converter is a 10 Amp, 140 Watt (continuous) unit. Heavy-Duty High Voltage DC to DC Converter with built-In Spike Filter. For operating standard 12 VDC equipment (lights, radios, cellular and tablet chargers, computers) from non-standard electrical systems. With the 24v-12v voltage reducer, you can run 12 volt auxiliary lights or any other 12 volt unit from your 24 volt truck.
Is your vehicle ex-military with a 24 volt system? Double battery 24 volt systems are superior 
in many ways to 12 volt models. Don't even think about converting the entire system to 12 volts. 
Also, it is not recommended to draw power from one battery only. Just use a converter to step 
down the voltage to power the 12 volt appliance.

These 6 & 12 circuit fuse blocks work excellently with our 24-12 volt converters. For example, it allows you 
to run 6 or 12 individually fused 12 volt circuits from your vehicle's electrical system. For ex-military vehicles, it 
allows running 6 or 12 individually fused 12 volt circuits from a single 24-12 volt converter, or 6 or 12 individually fused 
24 volt circuits directly from a vehicle's 24 volt electrical system.

Heavy-Duty Jumper Cables

(click image for large view)
Go Prepared! Professional jumper 
cables (booster cables). Unlike cheaper jumper cables, the handles won't twist or slip off, and 
the teeth remain sharp and grip well. Perfect for any emergency. Our jumper cables, are 
extra-long for convenient use, allowing use for the stopped vehicle in front. Fits Top & Side Mount Battery Posts.
Note: Gauge: Jumper cable ranges vary from 2 gauge to 12 gauge. Based on the scale, the 2 gauge is the heaviest duty model, while the 12 is a light-duty option.Remember the lower the number the better. Thick cables carry more electricity, allowing you to jump the battery faster.

QC Booster Assembly has:
- Quick-connect winch cable plug.
- 20' cable w/ battery clips & plug.
Always ensure that a quality 
receiver hitch that is rated for your vehicle is used to accept a self-recovery winch 
cradle.
If you have a winch mounted on a winch cradle 
enabling it to be used on several vehicles, you will need our Quick-Connect Booster Assembly. Instead of hard-wiring the 
winch to the battery, use the assembly with battery clips to quickly hook-up the winch on the 
go for easy removal and quick-connect functionality. The quick-connect booster assembly allows you to completely remove your 
winch from your vehicle for daily driving, and to use it with any vehicle that has a quality receiver hitch.
Our Quick-Connect Booster Assembly is professionally assembled and shipped ready for (ab)use.
