10 Things That Affect Off Roading and Why
Certain factors can make or break your adventure when it comes to off-roading. Power may seem important, but it’s not the most critical aspect.
Instead, factors like 4×4 capability, ground clearance, a robust drive-train, and good tires are essential for a successful off-road experience. Engine torque and suspension are also crucial in tackling uneven terrain.
This article will explore the factors affecting off-roading and why they matter. Read on!
1. Drive System
Your drive system can make all the difference regarding your off-road experience. While all-wheel drive (AWD) can be sufficient for exploring fire roads, a true 4×4 with a low-range transfer case is ideal for more challenging terrains.
This system provides an edge using low gearing to generate ample torque and enable slow crawling over obstacles. It also gives you greater control. This way, you can tackle even the toughest terrain with ease.
So if you want to up your off-roading game, consider upgrading to a true 4×4 with a low-range transfer case.
Another critical aspect of off-roading is your tires. Mud tires are a must-have, as even seemingly harmless trails can quickly turn treacherous with a little rain.
Even with a 4-wheel drive, good mud tires can be the difference between a successful excursion and a nightmare scenario. Traction, a function of tires, suspension geometry, differentials, and suspension travel, is also crucial.
Locking both axles ensures that all tires receive the same power, maximizing your ground clearance and enabling you to go further.
When choosing tires, look for ones with vigorous tread and sidewall bite and excellent durability to withstand sharp rocks and other hazards.
A smaller wheel and more sidewall can also aid your traction, especially when deflating your tires to a low PSI. Otherwise, power may seem essential, but it’s not the most critical factor in off-roading.
Instead, getting that power to the ground effectively is what matters. Size also plays a crucial role, with a narrow and elegant 4×4 often outperforming larger, bulkier vehicles. So when hitting the trails, ensure your tires are up to the task and prepare for an adventure!
The suspension system in off-roading is often misunderstood, and having a properly designed one can make all the difference.
With the right link geometry, sway bar rates, and shock travel/valving, you can easily conquer challenging obstacles while avoiding the bouncing and traction issues that less refined systems often encounter.
Contrary to popular belief, a quality suspension system can excel on and off-road.
The more severe the terrain, the more important it is to have a capable machine. Even a short-wheelbase Jeep or Cruiser with simple suspension modifications and larger tires can handle the terrain you mentioned.
Adding a winch for good measure is always a smart move. Get your suspension dialed in. And you’ll be ready to tackle anything that comes your way!
Power isn’t everything when it comes to off-roading. Instead, it’s more about the torque and having enough combined with low gearing to tackle any terrain at a slow crawl. Horsepower is not as important as torque.
The gear reduction, a combination of differential, transmission, and transfer case gearing, gives you the torque, control, and slow speed you need to succeed off-road.
Even with a bone stock 4.0 engine, having 5.38 differential gears and a 4:1 transfer case low range ratio made a significant difference in conquering difficult obstacles. You could even let your vehicle slowly crawl up a rock wall without being in the driver’s seat.
5. Ground Clearance
Ground clearance is important for off-roading, allowing vehicles to overcome bigger obstacles. However, suspension articulation is equally important.
Good articulation helps keep the tires on the ground, allowing the vehicle to put the power down and avoid getting stuck. Solid axles are best for extreme “flex,” but independent suspension with the right modifications can also work.
It’s not just about how high a vehicle is raised but also about creating clearance in other ways, such as minimizing what hangs below the belly, tucking link mounts as high as possible, and avoiding big dumb bumpers.
6. Approach And Departure Angles
Approach and departure angles are crucial, as are armoring up and getting the diffs as high as possible. However, building axles and suspension around tire size is key to avoiding damaging the vehicle.
Steering angles and geometric principles also come into play, making off-roading rigs quite complex. While these features aren’t always necessary, they’re generally the route to aim for.
Some off-road vehicles work for different reasons, such as rear-wheel drive and open-differential Baja Beetles and Sandrails.
7. Armor/Underbody Protection
Protecting your vehicle is crucial when off-roading, especially when tackling challenging terrain. Armor is a wise investment for any serious adventurer.
On that note, rock sliders are an essential piece of armor. They can save your vehicle from the most common type of damage- a crushed door sill. These heavy-duty protectors are designed to absorb the impact of rocks and other obstacles.
Skid plates are also good for the oil pan, t-case, and fuel tank. They provide an additional layer of protection against rocky terrain.
Knowing your vehicle is well-protected, you can confidently explore the most challenging off-road trails with the right armor.
Off-roading enthusiasts know that gearing and lockers are essential for tackling challenging terrain. Lower gears provide massive torque multiplication, which is crucial for pulling heavy vehicles over obstacles.
It also gives the driver greater control, vital when navigating rocky terrain at slow speeds. Offroaders can achieve different gearing options by modifying their transfer cases, adding additional gears, or automatic transmissions.
This can provide various options for RWD, RWD low, FWD, FWD low, 4WD, 4WD low, and double low. The ability to control your vehicle with such precision is remarkable.
Traction aids like sticky tires and deep tread lugs help to improve grip but often require the addition of a locker to get the power to the tires that need it. Lockers can come in different types, but they all serve the same purpose of providing additional traction to help get over challenging obstacles.
9. Recovery Points
Off-roading is an adventure that can quickly turn sour if you get bogged down, regardless of how capable your vehicle is or how popular you are on social media. Your vehicle must be equipped with rated recovery points to ensure a safe and sensible recovery.
These points are designed to handle the load generated during a recovery, something that factory underbody tie-down points are not built for. Don’t risk endangering yourself and others by using them.
Likewise, never put a snatch strap or tow rope over a tow ball, as it can lead to catastrophic consequences. Instead, invest in quality recovery points and have them fitted by professionals to avoid mishaps.
Always take the necessary gear, including rated recovery points, when heading off-road to ensure a successful and safe adventure.
10. Driver Skills
Off-roading may not always be a nail-biting experience. Even so, it requires certain skills to navigate obstacles successfully. The right path can mean the difference between making it through or getting stuck.
For instance, off-roading can be particularly stressful for those uncomfortable with heights. So it’s important to remain calm and focused. Then keep a watchful eye on the terrain.
Also, keep your thumbs up while driving rather than looping around the steering wheel. This can help prevent serious injuries in case of a sudden impact, as rocks hitting the tires could cause the wheel to jerk violently, leading to a painful experience if your thumb is caught in the wheel.

Note: A Bunch of the Things We List are Intertwined, Really
It’s important to note that many aspects of off-roading are interconnected. While tire size and tread are crucial, power delivery is just as important. This is where 4×4 and lockers come into play.
However, upgrading to larger tires often requires suspension modifications, which also affect keeping the tires on the ground through articulation and wheel travel.
Engine power is terrain-dependent, with smaller, lighter vehicles performing better on most terrain. However, larger vehicles have an advantage in fitting bigger tires and already having heavy-duty components.
The ideal off-road vehicle would be a custom build, featuring a small truck or SUV with a robust drive-train and suspension.
It’s worth noting that the equipment that makes a vehicle great off-road can compromise its on-road performance. Many modern manufacturers only offer specialized trim packages for hardcore off-road vehicles due to the high cost and weight of the necessary equipment.
Off-roading is not just about having a vehicle with high ground clearance and the right tires.
It’s a diverse activity that includes various forms of driving, from leisurely exploration to competitive challenges. Off-roading requires skill and knowledge of approach and departure angles and the best path.
Whether it’s taking a truck on a gravel road or riding dirt bikes off-road, the appeal of off-roading lies in the ability to reach places inaccessible by regular vehicles.
The thrill of going up steep hills and navigating tricky terrain makes off-roading an exciting sport, and the necessary knowledge of approach and departure angles, tire pressure, and optimal paths make it a skill.
While some may view it as simply exercising the capabilities of their off-road vehicles, for those who truly appreciate the sport, off-roading is about the connection with the vehicle and the challenge of conquering the terrain.
In that particular sequence, the key factors influencing off-roading performance are the tires, drive configuration, suspension, and engine torque. No matter how much power or torque you’ve got under the hood, it’s all for naught if you can’t channel it effectively.
As for the optimal drive configuration, 4-wheel drive reigns supreme- although AWD may be worth considering depending on the terrain. And pay attention to the suspension – it can make all the difference in traction on challenging terrain and safeguarding against damage.
