1.0 - Improved Dirt Road
- Dirt road that is clear and in good condition.
- Passable by most two wheel drive vehicles.
2.0 - Unimproved Dirt Road
- Potholes, minor wash outs, medium sized rocks and mud holes.
- Higher ground clearance helpful. Vehicle and Equipment Passable by most
stock 4x4 vehicles.
3.0 - Difficult
- Loose gravel, large pot holes, steep inclines, medium sized rocks.
- Four wheel drive required, tires with aggressive tread and lowered tire
3.5 - Hard Trail
- Some rocky sections, bypasses at most major obstacles. Some body damage
possible. Rocker panel and rear quarter panel protection helpful.
- Upgraded bumpers (Useable as a hi-lift point), rocker panel skids, skid
plates, Hi-Lift, 32" Tires, Rear locker
4.0 - Moderate Rocky
- Frequent ledges, crevices, large boulders, steep inclines and off camber
situations. Body and or tire damage likely. Spotters may be needed for some
obstacles. Low tire pressure required, good chance of loosing a bead.
Possible component breakages.
- Front locker, 35" tires, upgraded axles, lower ring & pinions, transfer
case gear reduction (w/ manual transmission), winch, recommend spare axles,
recommend spare steering parts
4.5 - Hard Rocky
- Same as a 4.0 rated trail but the obstacles are bigger, tighter squeezes
and bigger risks to body and mechanical components. Few bypasses if any.
Longer wheelbase vehicles may have problems with breakover angles, short
wheelbase vehicles may have to use a winch or strap on some obstacles. Large
vehicles will damage sheet metal. Spotter may be needed for all major
obstacles. Rollovers possible. Plan for common component breakages (vehicle
- 38" Aggressive off-road tires such as Swamper/Bogger/MTR, D44 or better
axles, source for on-board air, beadlock rims, flexible suspension, wider
than stock track width.
5.0 - Extreme Rocky
- Same as a 4.5 rated trail but the obstacles are bigger, tighter squeezes
and bigger risks to body and mechanical components. No bypasses. Body damage
guaranteed. Spotters needed for most of trail. Rollovers likely. Some
obstacles may require a winch for larger vehicles. Trail may be impassible
when wet. Plan for major component breakages.
- Realistically these trails should be run with rock buggies. Aggressive
off-road tires such as Swamper/Bogger/MTR. Transfer case gear reduction
(w/Automatic transmission). Remove all unneeded body parts. 100" Wheelbase.
5.5 - Insane Trail
- This type of run is pushing the outer limits of what is (currently)
possible. This is the same as a 5.0 rated trail except all of the obstacles
are bigger. Constant spotting required, vehicles will get hung up
frequently, undercarriage will catch rocks. At some point a winch will be
required to support the full weight of the vehicle.
- Light rock buggy.
