This is the GenRight Crawler Series Alien (formerly the RK Comp tank) Gas Tank to fit a Jeep TJ / LJ (1997-2006). It is specifically designed to work with the Rock Krawler Stretch kit and allow for more clearance between the Rear axle and the gas tank. This additional space can be used to move the Rear axle back up to 9 inches (8 inches on Dana 60) to Stretch your Jeep Wranglers wheelbase to well over 103 inches for the absolute best departure angle and vehicle capability. Just in case you did Not know, the GenRight gas tanks are unique in that they allow you to Stretch your vehicles wheelbase without cutting the frame and body as in the old days. This tank still mounts underneath, allowing you to still keep your back seat (or cargo area)! Why is Stretching the wheelbase Important? Well, once you are on 35 inchers or Bigger you have lifted the vehicle and geared it down. Now you have added traction and torque making the vehicle feel more unstable than it once did. Here is why: the height-to-length ratio (that the vehicle was originally designed with) has been altered. We all do it in search of more ground clearance. So now you can re-gain the proper height-to-length ratio for greater stability on Big tires ON and OFF road. Besides, everyone wants the better departure angle and improved driveline angles you get with Stretching the wheelbase (Not the body). FYI: We also offer two other Stretch models, for less Stretch, see the standard Comp model for 7 inches or the EXT model for up to 5 inches of Stretch.

- To install this tank in a 2003 or Newer Jeep, it might require a small (1 inch) body lift

- Due to the radical relocation of this tank (by about 9 inches Rearward) the installer Will need to careFully pull the fuel line and required electrical Rearward to reconnect them to the fuel pump module. Not a problem there is plenty of length in the lines, it just needs to be done careFully.
