Stock suspension and shocks from the vehicle manufacturer are not designed for much more than a measly dirt road – even in off-roading vehicles like trucks and Jeeps.  Over-used shocks develop a foamy oil due to heat buildup, which causes your shocks to lose their dampening strength.  If you decide to increase your wheel size, you’ll need to upgrade your suspension and shocks as well.  This will increase ground clearance, reducing your risk of serious damage to your undercarriage

Stock tires on off-road vehicles can be vastly improved with a set of more aggressive tires.  Increasing the width, tread, and height of your tire will increase your footprint for better traction and off-road capabilities.

Install a locking or limited-slip differential to improve your rigs grip and movability. This will help prevent instances where your vehicle is stuck because not enough wheels are touching the ground.

Taking your vehicle off road requires modifications to your intake system. A standard intake and filter will not be enough to stand up to the dirt and debris your engine needs. Without the clean air necessary for combustion, you’re going to experience serious problems with your engine.

Giving yourself every advantage when it comes to your line of sight is huge when you’re navigating rocky terrain. Upgrade your rig with additional lighting for maximized visibility at night.

Newer 4×4 vehicles come with an ECU (engine control unit) programmed with factory settings. Modifying this system can generate more power from your engine by altering top speed settings and rev limits.
