- Installation: Relatively simple, often requiring basic hand tools.
- Rock Sliders: Protect the rocker panels (the area below the doors) from damage when navigating rocky terrain.
- Benefits: Protection from rocks and other obstacles, added structural rigidity.
- Considerations: Weight, potential for reduced ground clearance, requires welding or bolt-on installation (depending on design).
- Off-Road Tires: Tires with aggressive tread patterns provide superior traction in mud, sand, and rocks.
- Types: Mud-Terrain (M/T), All-Terrain (A/T)
- Benefits: Improved traction in off-road conditions.
- Considerations: Road noise, reduced fuel efficiency, shorter lifespan.
- Winch: A winch is an invaluable tool for self-recovery when you get stuck off-road.
