Fitment Note: These adjustable LCAs do NOT
have any provisions for mounting a factory style rear sway
bar. These are race inspired rear lower control arms that should be used
in conjunction with an aftermarket
rear sway bar or anti-roll bar that does not mount to the
rear lower control arms.
The control arm bushings on the 1979-2004 Ford Mustang and
Fox Body cars have a significant impact on your vehicle's ride, comfort,
handling, acceleration, noise and
vibration. When the vehicle leans (rolls) in a turn, one
side of the chassis moves up relative to the rear axle and the other
side moves down.
The control arms must twist to allow for the axle to
articulate, this causes the control arm bushings to bind. If this bind
becomes excessive, it will raise the rear
wheel rate and produce sudden and uncontrolled changes in
handling such as snap oversteer.
The factory minimizes this suspension bind by using
compliant rubber bushings. These soft bushings help accommodate the
necessary motion of the control arms during
body roll. However, the rubber bushings do not provide much
in the way of forward and aft support which can cause wheel hop during
hard acceleration and braking.
It is common to replace the stock rubber control arm
bushings with polyurethane bushings to resolve the shortcomings of the
factory's soft rubber bushings.
Polyurethane bushings eliminate wheel hop, reduce axle
deflection, and improve straight line traction. However, the downside of
polyurethane bushings is they prevent
the necessary movement of the control arms during body roll,
which in turn produces significant binding in the suspension when the
vehicle is cornering.
The polyurethane bushings also place high stresses on the
control arm mounts on the vehicle. Polyurethane bushed control arms do
not allow for rotation of the control
arm during cornering because of the stiffness of the
bushings.

100% bolt in installation - Ships to you jig set at OEM length
- Available powder coated in your choice of the above colors for a brilliant and durable finish
These combo ended adjustable LCAs will wipe out most bind,
yet keep the road noise increase minimal for a street driven car. The
Del-Sphere pivot joints provide for
"bind-free" handling performance. They will work best when
combined with our
SKU# M4-605 Del-Sphere pivot jointed adjustable rear upper control arms.
