Trail Ratings - READ FIRST!!!
« on: July 01, 2010, 11:15:27 AM »
I thought it might be helpful to have a more organized place for AZ trail information. Please avoid posting directions & maps. This is a work in progress so comments & suggestions are welcome.  :)

Also, please do your best not to post pics or videos from areas that you know are not regarding the particular trail thread. If you are attempting to identify the trail and not sure please be clear about it. We want to do our best keep the trail info pertinent and as accurate as possible. Posting pictures or videos, or comments regarding other trails will make the trails thread confusing and difficult to use.

borrowed from AZVJC:
The following trail ratings are based on a Nissan Xterra or similar vehicle. The extreme trails realistically should be done with rock buggies or very highly modified vehicles. There is also simply no substitute for experience no matter the rig.

Trail ratings may seem subjective to some. This is an attempt to start with some idea of a standard that is somewhat consistent. These have been compiled based on many years of collective experience of some very experienced drivers. The ratings are intended to give people an idea as to what to expect.

There are many opportunties to break and cause yourself or others lots of grief or even misfortune on any trail. You can keep it a fun adventure with a little bit of preparedness and planning.

Always carry spare parts specific to your vehicle. Vital fluids both for yourself and for your vehicle are requiredfor your own safety in the desert. Recovery equipment, spares, tools and the knowledge to use them safely are highly recommended.

Please carry "pig pads" and "peat sorb" or equivalent products for cleaning up spills on the trail. Blue Devil Products has an excellent idea called a Trail Pail. It has everything you need to clean up spills completely and safely in one convenient bucket. Check with local retailers to see if they carry similar products, and if they don't insist that they do. Cleaning up accidental spills, our own or someone else's, will go a long way to show we deserve the right to access these resources.

Thanks & enjoy!  8)

Vehicle & Equipment: Passable by most high-clearance 2-wheel drive vehicles.
Example: Most Forest Service roads.

Rating 2: Unimproved Dirt Road
Description: Potholes, minor wash outs, medium sized rocks and mud holes. Higher ground clearance helpful.
Vehicle & Equipment: Passable by most stock 4x4 vehicles.
Example: Box Canyon, Gas Pipeline, East side of Table Mesa

Rating 3: Challenging Trail
Description: Loose gravel, large pot holes, steep inclines, 12-24" rocks.
Vehicle & Equipment: 4-wheel drive required, 33" tires with aggressive tread & lowered tire pressure helpful, rear traction device suggested.
Example: Log Corral Trail, Raw Deal, Upper Woodpecker, Martinez Cabins, Broken Arrow, Sunflower Mine

Rating 3.5: Difficult Trail
Description: Some rocky sections, bypasses at most major obstacles. Body damage possible for inexperienced or careless drivers. 16-28" rocks
Vehicle & Equipment: Upgraded bumpers (Useable as a hi-lift point), sliders, skid plates, Hi-Lift, 33" Tires, Rear locker.
Example: Judgement Day, Upper Terminator, Lower Terminator, Predator, Rocker Panel Pass, Martinez Canyon (not Cabin)

Rating 4: Moderate Rock Crawling Trail
Description: Frequent ledges, crevices, large boulders, steep inclines & off camber situations. Body and/or tire damage likely. Spotters may be needed for some obstacles. Lower tire pressure required. Possible component breakage. 18-36" rocks.
Vehicle & Equipment: 33" tires, 1 traction device, Upgraded axles, lower gear ratio, transfer case gear reduction (w/ manual transmission), winch, recommend spare axles, recommend spare steering parts
Example: Axle Alley, Bad Medicine, Highway to Hell, Lower Woodpecker, Lost World, Payeatt Draw, Squeeze Rock, Upper Firebird

Rating 4.5: Hard Rock Crawling Trail
Description Same as a 4.0 rated trail but the obstacles are bigger, tighter squeezes and bigger risks to body & 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 specific).
Vehicle and Equipment 35" Agressive off-road tires such as Swamper/Bogger/MTR, D44 or better axles, source for on-board air, flexible suspension, wider than stock track width.
Example Anaconda, Landslide, Overdose, Woody's Wash

Rating 5: Extreme Rock Crawling Trail
Description: 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.
Vehicle & Equipment: Realistically these trails should be run with rock buggies. 37" Aggressive off-road tires such as Swamper/Bogger/MTR. Transfer case gear reduction (w/Automatic transmission). Remove all unneeded body parts.
Example: Annihilator, Collateral Damage, Die Hard, Matrix, Skullcrusher, Twisted

Rating 5.5: Insane Trail
Description: 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. Skinny pedal will get a work out.
Vehicle & Equipment: Rock buggy on 39" sticky tires
Example: Asylum
