Quick Primer: Drivetrain Basics
2WD / AWD
Fine for dirt roads. Not recommended for serious trails.
4H (4-High)
For higher-speed traction: snow, loose gravel, mild mud.
4L (4-Low)
Low-range for slow technical sections: steep climbs, rocks, sand.
Pro tip: Shift into 4L BEFORE you need it — don't try to shift when stuck mid-slope.
Tires & Pressures
Tires are the biggest single upgrade for off-road performance. All-terrain (AT) tires are fine for most beginners; mud-terrain (MT) helps in heavy mud but is louder on road.
Tire Pressure Guide
| Terrain | PSI (Full-Size Truck) | PSI (Compact/Midsize) |
|---|---|---|
| Gravel/Dirt | 28-32 psi | 30-35 psi |
| Soft Sand | 12-18 psi | 15-20 psi |
| Rocks/Technical | 18-25 psi | 20-28 psi |
