10. The rear coils were upgraded to a set of the heavyweight coils from ARB/Old Man Emu, and the truck has never towed better. These coils use a massive wire thickness compared to the factory springs, and, though we found the new tow rating superb, the truck now sits high in the rear and has lost some of its twistability. Luckily, light- and medium-duty springs are available from ARB since customers in the Austrailian Outback have varying load requirements. We are considering upgrading to a slightly less rigid rear coil since the truck currently doesn't have a heavy rear bumper.
