A comprehensive guide to suspension lift kits
Suspension Lift Kits
All Comprehensive Guide
The purpose of a
suspension lift kit when installed in a car, truck, SUV or van, is to improve
its ground clearance. Improving a vehicle’s ground clearance allows it to
handle more easily on any type of unpaved surface such as gravel, desert,
rocks, sand, mud and even riverbeds. Don’t skimp on quality truck lift kits.
Get the best you can afford if you want to make off-road travelling smooth and
comfortable.
Why a suspension kit is better than a body lift
Modifying a vehicle
can be done with a body lift kit instead of a suspension lift kit, but the
latter is a superior choice. With the first option, there are spacers attached
to the frame on the mount of the body. This is done to add height to the
vehicle, which looks great, but doesn’t do anything practical. Suspension lift
kits are a better choice since they are practical and you can use them to make
off-road travelling better. Suspension lift kits are more costly than a body
lift but it’s the best choice for those serious about travelling on different
types of terrains. Suspension lift kits are highly recommended for those who
want to travel the most challenging trails and require adequate height,
superior handling and ground clearance.
How a suspension lift kit works
A suspension lift kit
increases the height of your vehicle by replacing the front and rear leaf
springs as well as the shocks on your vehicle. With the kit, the axles of the
vehicles are raised significantly above the ground so that it’s much easier and
comfortable to travel bumpy trails. Be aware that not every tuff country
suspension lift kit is made the same. Some are more basic than others. There
are kits that require the installation of additional components like steering
stabilizers to offset the altering steering geometry of the vehicle. Expect a
height increase of four to six inches typically, although there are some lift
kits that will add a foot and a half of height. While impressive, it’s not
suggested to use these specialized lift kits since they alter the vehicle’s
center of gravity which could make the vehicle unstable, alter safe handling
and ultimately make driving the vehicle more dangerous. Extreme lifts are
usually only installed for car shows a
Choosing the height
For off-road use, the standard height is four inches for a suspension
lift. There is the option to install a lift kit that adds more than four inches
of height to your vehicle, but a substantially raised ride can compromise
safety. It’s important to be aware of all the safety precautions. Be aware that
the higher the vehicle the more difficult it will be to make sharp turns or
avoid any type of obstacle. A tuff country EZ ride that is higher than four
inches can cause you to topple over should you find yourself in the situation
where you need to quickly jerk the wheel. In the worst case scenario, this
could cause death.
When driving in a vehicle that has been substantially raised, it’s
extremely important that care is taken when driving on off-ramps and along
freeway interchanges with banked turned since the higher suspension will cause
the vehicle to tilt over. Also be aware that with a lift kit, you will get a change
in perspective when you’re driving. You’ll be up higher so it may be more
difficult to see smaller obstacles on the ground. Driving with a lift kit will
affect your vehicle’s performance and dynamics, so you’ll need to once again
learn what your vehicle can do and how to drive it.
Getting bigger tires with your
suspension
Many off-roaders like the idea of tires two sizes larger than the stock to
provide more traction on bumpy trails and make the ride more comfortable. In
order to accommodate such large tires, it’s necessary to install suspension
lift kits. Skyjacker lift kits are often used and if this is your goal, be
aware that your vehicle’s speedometer and odometer will no longer work. These
calculations are done according to the stock’s circumference and your new
bigger tires will have a completely new circumference. You’ll need to re-gear
the rear end to keep your mileage as close to stock as possible. This is done
using gear ratio charts which are easily accessible online. To use one, all you
need to do is enter the stock gear ratio and tire size or the VIN (vehicle
identification number).
If you want to simply
get a suspension lift, you can keep your stock tires, but they will look a lot
smaller once you raise your vehicle. Your vehicle will look better with larger
tires, but there are some downsides. Bigger tires are usually noisier and can
be uncomfortable when highway driving. They tend to wear out faster on paved
roads and provide poorer traction on wet roads. Choose to switch stock tires to
off-road tires if you’re planning to enjoy a significant amount of off-road
driving, but keep the stock tires if you’ll be travelling mostly on paved
roads.
Installing suspension lift kits
If you’ve decided to
increase the height of your vehicle, the good news is that there are many
DIY-kits available for the handy person. They provide detailed instructions
that walk you through every step. The skyjacker lift kits, for example, are
fairly straightforward to install if you have the proper skills and tools. But
to make sure all the equipment is correctly installed, it’s much more
convenient to hire a professional mechanic to do this for you. This way you’ll
be guaranteed professional results which you may not get if you have no
experience in automotive mechanics and dynamics.
Aftermarket suspension
kits are available for all sorts of vehicles, and you may be surprised with the
selection. But choosing the right one is crucial. Every state has laws
regarding the height limits and legal suspension limits of vehicles. Make sure
you know what they are by contacting a local 4x4 shop before you buy a
suspension lift kit. And be aware that
any modifications to your vehicle may void the manufacturer’s or dealership’s
warranty.
