550 horsepower. Full-bodied Jeep LJ comfort. Zero weak points. Rob Fox came to Wide Open Design wanting one rig that could do everything:
√vertical climbs at Adventure Off Road Park
√technical rock crawling
√weekend trail rides with the family
√high-speed trail sections
√all while still looking like a clean Jeep LJ
The result is this incredibly balanced custom LJ powered by a naturally aspirated 402ci LT engine making 550 HP backed by a TH400 and Atlas 4-Speed transfer case.
