Our
2x4 Suspension Systems use an Equal Length I-Beam Setup
Many
of our customers have asked "Whats the difference between
our I-Beams and our competitors?"
| Why
Equal Length is better |
| Un-equal
Length (Factory Ford I-beams) = Drastic Camber

At
McNeilOff-Road, we incorporated
extensive racing technology and experience to develop long-travel
bolt-on suspension systems that bolt in place of the stock
suspension. Equal Length means that both I-Beams are identical
in length. Factory Ford trucks come equipped with UN-equal
Length I-beams. One factory I-beam can be up to 6 inches longer
than the other depending on the model truck. Equal
Length I-beam front suspension systems have
less camber change, or "camber curve" than
the Factory Un-equal Beams.
Camber
Explained
Positive
Camber Change occurs when
suspension is in full droop |
Negative
Camber Change occurs when suspension is bottomed out |
Less
camber change results in more wheel travel. Many factory suspension
systems are limited to 8 inches of travel, but can be replaced
with our bolt-on kit to achieve from 18 to 25 inches wheel
travel.
Unless
you have Robby Gordon type technology most A-Arm set-ups don't
offer as much travel as an equal length I-Beam. The reason
why A-Arms are preferred is because there is no camber change
as the suspension cycles from full droop to bottoming position.
The tires will stay straight.
Our
competitors offer I-beams that bolt into the stock pivot brakets.
One of these brakets is near the center of the frame rails.
Although these factory replicas give the truck a nice look,
the camber change is too drastic for optimum performance because
only one of these pivot brackets is near the center of the
truck. Our Equal Length set-up is built with custom pivot
brackets that locate the i-beams straight down from each frame
rail. The extended wheel track ends up being 4.5 inches wider
on each side, but one I-beam is up to 12 inches longer than
the stock beam. This can only be achieved with equal length
set-up.
Wheel
Caster
Wheel
caster is an alignment measurement found in all vehicles,
and is very important for wheel traction. When most people
think of traction the first thing that comes to mind is Tire
quality. Just as new tires provide more traction, additional
caster built in to the geometry of the suspension will also
provide better traction for mor precise cornering capabilities.
Our kits are designed with 10° of wheel caster. This makes
the tires grab the ground, cut and turn the vehicle better.
Ride
Height
Ride
height is the height that the vehicle sits when not in operation.
Our suspension systems give the truck an additional 5.5 inches
of ride height or "lift" so the vehicle has plenty
of up and down travel, resulting in a smooth off-road ride.
Our suspension systems use a 0-degree alignment cam. The trucks
alignment remains perfect with the 5.5 inches of lift.Our
suspension systems are completly adjustable in height. Any
McNeil lift may be lowered 2.5 inches or raised 2.5 inches
(camber correction required).
