Jeep JK (2 Door) Stretch Gas Tank & Steel Skid Plate (22 Gal)

1 review Write a Review

This is the new tank from GenRight Off Road to stretch the rear axle back up to 5" on the 2 door Jeep JK!

Building your JK into the ultimate rock crawler? Then we have the tank so you can put a 4-Link rear suspension in you Jeep JK.

This is the GenRight Crawler™ Gas Tank to fit a Jeep JK (2007 - Current). It is specifically designed to REMOVE & replace the factory tank from under the middle of the vehicle so you can run true Rock Crawling triangulated 4 link rear suspension (yes, no trac bar!).

This tank follows in a line of innovative and trail proven, top quality gas tanks produced by GenRight. 

This new JK tank assembly is designed to fit in the rear muffler area and mounts in a way that still works with your factory gas filler. It even re-uses your factory fuel pump module so can work with all your factory emissions equipment so you won't get any check engine light or have computer issues.


  • Reshaped tank creates room for up to 5" of rear axle stretch.
  • Rear mounted tank allows for the better triangulated rear 4 link suspension systems.
  • Mounting location keeps center of gravity low.
  • Hi Clearance (no lower than the factory muffler, does not hurt departure angle).
  • 22 gallon fuel capacity.
  • Re-uses the stock Jeep fuel pump module (or the Aeromotive Phantom).
  • 1/8" thick Aluminum alloy tank is TIG welded.
  • Foam liner between tank & skid plate.
  • Includes a 3/16" thick heavy duty steel skid plate, powder coated.
  • Stainless steel hold down strap.
  • All tanks are 100% pressure tested.
  • Patent Pending.
  • 100% Made in USA!



  • Fully assembled fuel tank in a Heavy Duty skid plate.
  • New factory Mopar roll over / vent valves.
  • New tubing to adapt tank to new mounting location.
  • New aluminum cargo area floor cover.


Additional NOTES:

  • This tank was designed to be used with our 2 door JK Stretch suspension kit.
  • Because of shape and location changes, installation of this product requires changes to the exhaust.
  • Requires removal of the rear floor tool storage area (the jack remains in the very rear compartment).
  • To install this product it does NOT require a body lift.
  • If a rear sway bar is desired, installing this tank will requires switching to a Currie "AntiRock" type rear sway bars. Because the stock sway bar must be removed.
  • Reconnects to the factory EVAP system, but is only CARB compliant (not smog legal) therefore only for Off Highway Use in California.

    Thanks to this gas tank I am now able to run a triangulated four link on my JK. The fuel tank took care of the low hanging under belly. I love that I don’t have that loss of ground clearance anymore.
