NEW & IMPROVED 12 Gallon Trail Trekker II™ Tank

Availability: In stock

When you hit the trail you can always use a little extra fuel, right? TITAN’s Trail Trekker II™ gives you the fuel you need to go boldly off the beaten path. This new, improved version of our popular off-road product features better rear visibility, improved looks, and now will not only fit 5” bolt stud patterns, but 6” and 8” as well! So if you go off-road with most of the popular “rock crawlers”, you too can have the added peace of mind extra fuel brings. Of course we still fit Jl, JK, TJ and YJ Wranglers. The Trail Trekker II™ is made of TITAN’s famous Military Grade, Cross-Linked Polymer so you know it’s backed by our Lifetime Warranty and is tough, durable and secure. The tank is fully grounded and vented with rollover protection. It fits the stock Wrangler spare tire carriers and most of the popular aftermarket tire carriers, and comes with all of the high-strength steel bracketry, fasteners, and accessories for easy mounting on your off-road rig. The mounting position keeps the tank out of the way and makes transfer of fuel to the vehicle’s main tank a snap. The Trail Trekker II™ will handle 15” and larger wheels, and tires up to 37”.


Note: Fits vehicles with 5x4.5", 5x5" and 5x5.5" lug patterns..

Note: We now offer a Trail Trekker specifically for the JL chassis, please see the 4040487. If you have a 4040287 and want to fit it to you new JL you can purchase the lug, brake light extension and rear camera mount on the Trail Trekker main page.

Note: On stock TJ and YJ Wranglers, the tank will greatly limit the opening of the glass lift gate on vehicles equipped with a factory hardtop.
