So you've just bought a brand new (or
new to you) 4x4. Looking through countless magazines,
you see a seemingly infinite parade of vehicles outfitted
to the nines with thousands of dollars worth of accessories.
Online forums crawl with users talking about their
latest modifications. The suggestions and possibilities
can seem a little bit overwhelming and confusing.
With your new vehicle purchase you may
not be flush with cash, so you want to make sure that
every modification is a wise one and that your money
is well spent. So where do you start?
First and foremost, you want to make
sure that before you even leave the pavement, your
vehicle is equipped with a proper recovery kit. At
the most basic level, your vehicle needs front and
rear recovery points, a Hi-Lift jack, a tow strap
with closed eye loops, a pair of leather-palmed work
gloves and a few load rated shackles or d-rings.
To keep the gear from getting thrown
around in the back of your truck, we recommend getting
a recovery bag such as those made by ARB. These bags
are available in a variety of sizes, but you should
get a larger one, as you will add to the kit as your
skills and accessories develop.
With a basic recovery kit and a companion
vehicle for trail runs, you will find that you can
extricate your vehicle from most recovery situations.

Upgrade Your Skills
Suprisingly enough, the first, most
significant upgrade is also the least expensive...your
driving skills. While many drivers feel that to get
the most out of their vehicle they must pour thousands
of dollars into outfitting it, the truth of the matter
is that in the majority of situations a stock vehicle
is much more capable than a stock driver. You should
get some seat time in your new vehicle in its stock
form. Learn to make the most of its capabilities and
you will find that your driving skills will change.

For example, the Land Rover Discovery
Series II vehicles come with a sophisticated traction
control system. This system operates by detecting
wheel speed and engaging traction on the wheels that
have grip. However, by feathering the brake pedal
in loss of traction situations, you can "trick"
the system into engaging earlier, thus getting more
traction before precious loss of momentum occurs in
that steep uphill climb.
If you're really serious about upgrading
your skills, there are a number of high quality teaching
companies available world wide with whom you can further
learn the nuances of off-road driving techniques.
Within the United States, some of the better institutes
are Overland
Experts, Overland
Training and the "granddaddy" of them
all, Bill
Burke's Four Wheeling America.
High quality classes will teach you
not only driving skills, but also proper vehicle recovery
techniques, spotting techniques and environmentally
responsible four wheeling. These learned skills will
help later on down the line as you will be able to
get the most performance out of future modifications.
Furthermore, these valuable skills will help you in
the future if you decide to drive other vehicles off
road.

Protection
is key
Once you can get the most performance
out of your vehicle in stock form, then it's time
to begin thinking about modifications. While these
recommendations apply specifically to the Land Rover
product line, however the same concepts and theories
apply regardless of vehicle manufacturer.
For Land Rovers, the first and most
important modification that we recommend is vehicle
protection. Primary amongst these are diff guards.
While relatively strong, the Land Rover differential
is incased in a housing that has a very thin metal
housing on the front end. Off road, it is easy for
a large rock or boulder to hit and bend or puncture
this housing. Repairing this type of damage on the
trail is not only difficult, but time-consuming as
well. We recommend fitting a heavy duty differential
guard such as those made by Safari
Gard or Rover
Tracks.

The other vulnerable part on Land Rovers
is the door sills. The long wheel base of vehicles
such as the Discovery, Range Rover and Defender 110
make the door sills and the lower door vulnerable
to damage from large boulders. The best modification
is to install a heavy duty rock slider, such as those
made by Slick
Rock Fabrication. This modification will easily
pay for itself the first time your vehicle gets high
centered and the sliders save your vehicle's doors.

Wheels, Tires
and springs
With only a handful of exceptions, most
vehicles come from the factory with tires that are
biased towards on-road performance and longevity than
off-road traction. Many of these tires have soft sidewalls
or tread patterns that underperform in challenging
off-road conditions.Which tires you change to is largely
a matter of preference, as well as what features you
are willing to compromise on.
For example, an excellent, moderate
off-road tire such as the BFGoodrich All-Terrain makes
for a good compromise tire. It provides improved off-road
performance with good street manners and excellent
tire longevity. For additional off-road performance,
you can upgrade to BFG Mud Terrains, Goodyear MT-Rs
or even Super Swamper tires. However, in almost all
cases, you'll increase on-highway ride handling, noise
and tire longevity.
|
 |
For many people, when they upgrade their
tires, they also want to go with a larger tire size.
Tire size is primarily dictated by wheel arch openings.
In order to fit larger tires, you can either cut out
the wheel openings (a very permanent modification),
or add a vehicle lift. Contrary to popular belief,
the lift itself does not allow for the fitting of
larger tires. Room for additional tire size is dictated
primarily by the amount that this addtional lift limits
axle-up travel. For example, the thicker coils of
an Old Man Emu suspension actually reduces up-travel
on most Land Rover vehicles by almost 2", thus
allowing the fittment of larger tires.
|
 |
At the same time, fitting the taller-than-stock
OME coils allows for additional down-travel in the
suspension IF matching shocks are installed at the
same time. Matched OME shocks allow for 2" of
additional down-travel. This means that while suspension
droop is increased by 2", up-travel is also limited
by 2", meaning there is no net gain in suspension
travel overall.
Adding this heavy duty suspension will
benefit your trucks off-road performance by improving
a number of critical angles on the truck. |
 |
The higher
the truck sits off the ground, the greater the approach
angle is. This means that you are less likely to bump
against rocks on the trail as you drive over them.
You will also have a bit more choice in routes that
you can take over obstacles. Break-over angles are
improved as well, making it less likely that your
vehicle will get hung up on rocks or high-centered.
Finally, departure angles are also increased. The
higher your vehicle's departure angle, the less likely
you are to drag the rear of the vehicle or get hung
up climbing steep obstacles or descending off tall
rocks.
|
 |
With the new lift and tires, off road
performance should increase significantly. The higher
lift allows you to pick your line better and clear
obstacles easier. Your new tires bite on the rocks
and dig through the mud easier, and with your improved
driving skills, you are now getting the most out of
your 4x4. The next step to maximize your off-road
performance is to protect the front end of your truck.
The factory front bumper can get scratched easily,
it offers minimal front end protection, and the approach
angle can be abysmal on some vehicles. |

Protection
part 2
To match your vehicle's newfound capablities,
we recommend considering an upgrade to your vehicle's
front bumper. A heavy-duty bull bar will help provide
valuable front end protection, increase approach angle,
plus provide the option for adding additional off-road
accessories like a winch or auxilliary lights down
the road.
There is a myriad of options available,
but we're partial to the ARB
bumpers (they not only protect but also compliment
the lines of most vehicles), and the Safari Gard bumpers.
Each has its pros and cons (the ARB is more widely
available while the Safari Gard offers a better approach
angle) but either choice is a significant upgrade
from the stock front bumper.
|
 |
The next modification that we recommend
won't improve your vehicles handling or performance,
but it will make a significant contribution to enjoyability--
organization. There are a multitude of ways to organize
your vehicle, some of which we'll get into in future
articles, but whatever direction you take, establish
a consistent, reliable packing system. This will ensure
that you not only remember every item that you need
for the trail, but you'll also be able to find it
with ease when you get to your campsite at the end
of a long day. |
 |
And then...?
With this handful of simple modifications,
your vehicle should now be a much more capable machine,
able to handle the harsh trails of the remote back-country.
Unfortunately, upgrade choices and direction from
here are much less clear and more subjective: Those
who prefer to travel alone might consider a winch,
while a driver drawn to hard-core four-wheeling may
find their money more well spent on lockers and gear.
For whatever you decide to do with your
vehicle, following these simple steps will ensure
a pleasant, relatively pain free introduction to the
world of four-wheeling and overland travel. The end
result is a vehicle that can get out there and help
you discover the world.
