The Wrangler is a well-known performance car in the off-road circle. As a direct descendant of the famous Willys ( Willis ) during World War II, it also inherits the excellent blood of its ancestors, whether it is on the battlefield filled with gunpowder or in cities in peacetime Highway, you can find the reason for its existence.
The 2018 Rubicon model is equipped with a 2.0t engine with a maximum power of 266 horsepower and a maximum torque of 400 Nm. It adopts an eight-speed automatic manual transmission. From the perspective of power parameters, the power level is almost the same as that of the 17 3.6L models. However, in extreme environments, the low-speed and high-torque characteristics of the 3.6L self-priming engine cannot be achieved by the 2.0t engine. Therefore, for those professional players, The power output of the large-displacement self-priming engine enables the vehicle to be easily driven off-road.
All-aluminum fragmented front bumper, with original car probe mounts (I don’t know if these probes can still be kept after off-roading)
The AT twisted tooth bracket is good, very powerful and strong!
Changing the speed ratio of JL Rubicon is not as simple as that of JK. Because the solenoid valve is too large, the speed ratio gear cannot be inserted directly. Only the electric lock bearing and the solenoid valve can be removed to disassemble the speed ratio gear.
It is a technical job to remove the bearings on the electric lock.
Here is a comparison of the details of several mechanical hardware of JL and JK that are obviously different:
There is an extra solenoid valve on the right half of the front axle, which is the disconnect function of the front axle. This function is definitely a major upgrade. The front half shaft is disconnected, which can realize the two-wheel drive state. The front drive shaft does not need to rotate with the tires, and the body will be more stable when driving at high speed.
There is an extra stepping motor at the end of the transfer case, which should be the center differential lock of the full-time four-wheel drive.
The horns are changed from cast iron to high-strength aluminum alloy.
The calipers are significantly different in size.
