The AEC RAM 1500 with Prins LPG System extends your range with the addition of up to 2 LPG tanks, without any compromise on performance.

Top quality LPG conversion gives you the flexibility to use either gas or LPG without impact on the power of the legendary HEMI V8 engine.

Both AEC and Prins ensure high quality installations and rigorous testing  performed by experienced professionals at the our Vehicle Processing Center in Antwerp, Belgium.

Thanks to Prins validated software and accurate calibration tested on a dyno bench, the RAM 1500 with LPG System performs optimally in all circumstances.

The benefits of LPG as an alternative fuel are both economical and practical: not only is LPG fuel more affordable than gasoline, but it also offers range extension. RAM 1500 with the 5.7L V-8 Hemi® (Consumption and Emission here) engine paired with VSI-2.0 LPG System gives you range  up to 1.800 km (both LPG tanks and gasoline combined)

The standard fitting 122L (approx. 98L fuel capacity) space-saving round underbody tank is fitted in place of the spare tire.

An additional optional 200L (approx. 160L fuel capacity) cylinder tank can be installed on the truck bed at a cost.

When combined, both tanks (122L + 200L) will be refilled through one filler neck fitted on the rear bumper. The 200L tank is used first before seamlessly switching to the 122L tank.

What are the advantages of the AEC Prins VSI-2.0 LPG system?

AEC Prins VSI-2.0 1-Vaporizer Non-AEC System 2-Vaporizers
Full power 5 – 10% power loss
Peak power: 401 hp | RAM 1500 models with the available V8 petrol enginges: Fuel consumption (combined): 14,9 – 12,8 l/100km; CO2-Emissions comb.: 352 – 298 g/km; CO2-Efficiency class: G-E* Peak power 360 – 380 hp
Smooth seemless adding of petrol only at peek for full power – less than 1% petrol of total consumption Full power can´t be reached due to the impossibility to add petrol at peak power
AEC specialized calibrated software incl. regular updates Individual calibration by workshop mechanic leads to worse performance
Certified by PRINS as 100% solution for the RAM Hemi® engine | RAM 1500 models with the available V8 petrol enginges: Fuel consumption (combined): 14,9 – 12,8 l/100km; CO2-Emissions comb.: 352 – 298 g/km; CO2-Efficiency class: G-E* Non-certified solution
Plug-n-Play solution: professional installation due to standardised cabels and components as well as uniform construction manual Not Plug-n-Play: every garage has its own installation style – too long and disorderly laid cables, individual solutions
AEC Vehicle Processing Center manufacturer assembly guarantee a professional, consistent and high quality installation Small garages that cannot support the same high quality installation due to lower volumes
Sourced and guaranteed by the same importer – one point of contact Multiple-points of contact (Manufacturer, warranty, importer, workshop, etc.)
Manufacturer controlled final inspection No centralized final inspection by manufacturer or importer
Continous improvement of hard- and software due to experience of high volumes Smaller volumes lead to less experience

Why should you go for a AEC RAM 1500 with Prins LPG System?

Long Driving Range

  • RAM 1500 with LPG System offers an amazing long driving range with up to additional 1.300 km
  • Option1: 122L gross (net: approx. 98L) space-saving underbody tank
  • Option 2: 200L gross (net: approx. 160L) installed on the bed (with metal cover)
  • Anytime you are running out of fuel, the system switches automatically to petroleum gas and vice versa

  • No special tools needed to fill the tank – Vehicle comes with three adapters
  • Easy and reliable refueling by advanced systems


  • RAM 1500 models with the available V8 petrol enginges: Fuel consumption (combined): 14,9 – 12,8 l/100km; CO2-Emissions comb.: 352 – 298 g/km; CO2-Efficiency class: G-E*
  • LPG is up to 50% cheaper than gasoline
  • Fast Amortisation of installation costs
  • V8 Sound & Power remains

Which are the available options?

122L underbody tank

The well-known 122L gross tank (net: 98 liters) is installed in the recess for the spare tire under the bed. Depending on the driving style this offers an additional range of 500+ kilometers.

200L cylinder tank

Alternatively, a tank of 200L gross (net: 160 liters) is installed across the bed. The tank sits thereby space-saving at the tailboard. Thanks to an safety cover, the tank is protected against weather effects as well as damage caused by transported goods. The driving range is more than 800 kilometers depending on the way of driving.

322L combination

With AEC it is even possible to combine both our tank options! This results into a total LPG range of over 1.300 kilometers, with the petrol tank even up to 1.800 kilometers.

What happens with the AEC Warranty?

All AEC vehicles continue benefiting from our warranty products. Thus, only a small fee is assessed for vehicles with LPG systems to continue the protection of the AEC vehicle warranty for your desired duration (24, 36 or 48 months) and the desired extent (Premium Warranty). All parts of the LPG system are covered by a three-year manufacturer warranty by Prins.
