Traveling on off-road terrains require vehicles capable of accommodating off-road driving such as ATVs. These vehicles accommodate off road conditions with extended ground clearance, off-road tires and drive-train. Some manufacturers offer vehicles specifically meant for off-road use.
While production vehicles with off-road capabilities can travel on unsurfaced roads, modifications are needed to travel on terrains exceeding capabilities of original configuration. The following are some of the modifications made to off-road vehicles.
A vehicle lift is when the vehicle is raised to increase the amount of clearance between the ground and the bottom of the body or frame of the vehicle.

A lift will also help with tire clearance when going over large obstacles with only one or 2 wheels and allow the vehicles differential to flex without having the tires rub the fenders. There are several methods for vehicle lift. Some methods may be combined together to best fit the needs.
This is a method that is only usable on body-on-frame design found in some pickup trucks and some SUVs. A body lift is performed by placed spacers in between the normal mounting points of the vehicle’s chassis and body. These typically are between 1 to 4 inches (25 to 100 mm). When a body lift is installed on a vehicle it is very common for linkages and other components on the vehicle to need drop brackets to function properly after the lift. Raising the body permits the fitting of over-sized tires.
A suspension lift is a modification to vehicle’s suspension system that includes a lengthening coil springs or re-arching leaf springs to make them taller

Doing this will make the vehicle taller and make the approach, departure, and breakover angles better for off-roading. Increasing the distance between the axles and body of a vehicle drastically often requires the replacement of other parts in the suspension system to make it work correctly again.
A block lift (often referred to as a budget lift) is a modification that is similar to a body lift in the way it works, but used in a different location. Block lifts are used to provide more room between the body and axle of a vehicle for larger tires. A block lift consists of either extended spring isolators or blocks that are inserted between a vehicles axle and spring, or a spring and the vehicles body. This type of lift is often preferred due to the affordability and ease of installation.
