Key Features:
  • Broad Vehicle Compatibility: Crafted to accommodate a wide variety of vehicles with carburetors. Our kit guarantees a versatile fit and optimal performance enhancement.
  • Simplified Installation: With easy-to-follow instructions, the conversion process is made accessible for both amateurs and seasoned professionals.
  • Eco-Friendly Fuel Alternative: Transitioning to propane significantly reduces your vehicle’s emissions, thanks to its cleaner combustion that emits fewer greenhouse gases compared to conventional fuels. This also means that your engine oil stays cleaner between changes keeping your engine running cooler and increasing the longevity of internal moving parts. No more smelling like Gas after going for a ride!
  • Cost Efficiency: The affordability of propane over gasoline or diesel, combined with the decreased maintenance demands of propane-fueled engines, delivers considerable long-term savings. No maintenance is required for this kit other than cleaning your air filter. And since propane doesn’t go bad like gasoline does, you can let your vehicle sit without worrying about rotting tanks and gummed-up engines.
  • Enhanced Performance: By adopting propane, you not only contribute to a healthier planet but also get increased performance benefits. Our propane conversion kits offer unmatched reliability, safety, and sustainability compared to running gasoline. No more flooded or starved carburetors, just consistent fuel delivery no matter if you are cruising on a country highway or rock crawling. Most of our kits will actually improve your overall performance and drivability.

Easily retrofit that older Jeep now without the worries of wiring, fuel pumps, etc.  Our propane conversion kits for the Jeep 4.0L are designed to run strictly on propane. You no longer need the wiring harness or sensors. You will need to put a distributor in from an earlier carbed motor to eliminate the computer. This is designed to re-use your stock intake manifold. If you are using an automatic transmission you will need a stand-alone transmission controller. These are not approved for emissions-controlled vehicles.
