1. Tyres
The standard tyres of most 4WDs are not specifically designed for outback travels and will most likely fail during a steep and heavy drive. As part of essential 4x4s Modifications, your new tyres should be robust enough to manage rough roads and long trips. Tyres with light truck construction are recommended rather than those with the usual passenger construction. This is because light truck tyres have a stronger carcass and thicker sidewalls. They are particularly designed to carry heavy weights and handle higher pressures. Generally, light truck tyres are less prone to damage compared to passenger tyres.
Bigger tyres are usually preferred, as they can raise your 4WD higher. However, the size of the tyres depends on what fits the vehicle. As part of practical 4x4s Modifications, the final gear (i.e. the last gear before the power moves to the wheels) may also require adjustment because the engine will rev less with a larger wheel diameter.
2. Long-Range Fuel Tanks of 4x4s Modifications
If you’re planning to travel to remote areas with your 4WD, you need to ensure that you have enough fuel. However, carrying extra fuel may be bothersome or risky. As one of the essential 4x4s Modifications, upgrading to a long-range fuel tank is recommended. Long-range fuel tanks allow you to carry enough fuel for your long drive, and you can place the tank under your vehicle so no extra space is occupied.
3. Snorkel
You may encounter deep mud pits, sandy roads, and even flood water when travelling to remote areas. Among the most practical 4x4s Modifications, adding a snorkel will help prevent mud, sand, dust, and water from entering the 4WD’s engine, as long as the level doesn’t exceed the height of the snorkel. You can also add a special sock to the top of a snorkel as a second air filter. This can prevent really fine dust particles from going inside the engine.
4. Bullbars
Adding a bullbar in your 4-wheel drive is important because it protects the front of your vehicle from animal attacks and other types of damage. As part of effective 4x4s Modifications, bullbars can also serve as a convenient location for aerials and lights. If you want to mount a winch on a bullbar, you’ll have to choose a winch-compatible bar instead of a standard bar. Furthermore, make sure that the bullbar is compatible with airbags.
5. Diff Lockers or Traction Aids
Diff lockers, or traction aids, help prevent damage to the driveline when travelling through rough roads and tough terrains. As one of the advanced 4x4s Modifications, diff lockers are crucial because driving on rough roads or uneven terrains can cause either/or both front and rear wheels to lift off the ground or lose traction. A fast spinning, lifted wheel that suddenly hits the ground can disable your car or cause certain components to break.
A diff locker locks the differentials (both axles and/or wheels), forcing them to rotate at the same rate and allowing the disabled vehicle to move forward. It’s essential to know the right time to switch the diff lockers on and off.
6. Satellite Phones for Communication
Outback travels are usually long, and remote areas may not have network signal for your mobile phone. As part of thoughtful 4x4s Modifications, carrying a satellite phone is a smart move. If you want to communicate with your relatives or friends, or if you need to contact people in case of emergencies, then a satellite phone is the best solution. Make sure you fully charge your sat phone and keep it safely inside the vehicle to avoid damage in case of accidents..
