The Jeep Wrangler is one of the most popular SUVs in the off-road scene. Beating its competitors for its off-road capabilities and well-loved for the iconic Jeep seven-slot grilles, it is no wonder that the Wrangler has become the face of Jeep over the last 30 years.
Today, we find out what makes the Jeep Wrangler the excellent off-road vehicle that it is.
QUADRA-COIL 4-LINK SYSTEM
For the longest time, off-road vehicles have used leaf springs as a suspension in the wheels. Leaf springs are sheets of metal that are stacked together and attached to the axles of each wheel. These are made for supporting and carrying heavy loads on vehicles, but come at the cost of a really uncomfortable ride during normal daily usage.
Jeep introduced the Quadra-Coil 4-Link System in their Jeep Wrangler back in 1997 as a replacement for the traditional leaf springs. Instead of a rigid stack of metal sheets, the suspension uses a single metal that is coiled like a spring to create a coil spring. Coil springs give an extra amount of compression and flexibility to absorb the shocks of any uneven pavement, while keeping the vehicle relatively stable during normal circumstances.
There are primarily two types of axles that vehicles can choose to use – solid axles (also known as straight axles) and independent axles. Jeep Wranglers have been using solid axles since its introduction, and there are reasons for choosing to use them instead of independent axles.
For starters, solid axles are much easier to replace compared to independent axles, since it requires fewer parts to function. Additionally, the solid axles are more durable than most independent axles as both wheels are connected to the same metal housing. With lesser amounts of power being lost in transmission, more torque can be employed on the front and rear wheels.
Of course, what sets the Jeep Wrangler apart from other off-road SUVs is the customisability and after-market support provided. Tuning and modifying your Wrangler is a large after-market service provided, as Jeep aims to supply different coil springs, straight axles, and shock absorbers tailored to any terrain that you would be driving on.
