PowerFlex Black Race Bushings!
For 15 years
Powerflex have been the market leader in high performance
polyurethane suspension bushes with the widest and fastest growing
"street" bushes are developed to offer the best of all worlds
are a number of applications where chassis performance is the only
consideration. For the
ultimate in performance Powerflex introduced The Black Series, a new
range of bushes developed for Race, Rally and Circuit
for the Track - Ready to Race - Engineered to
be the best
Black Series bushes are manufactured using a 95 Shore A compound
to provide maximum control of chassis geometry.

stiffer than PowerFlex purple ("street") performance material.
requirements are purely for the ultimate in handling and chassis
performance then Powerflex Black Series are unique, offering the most
precise and accurate alignment for your chassis.
- Developed for ultimate performance using the toughest materials.
- Engineered for the most accurate control of chassis geometry.
- Manufactured to be easily fitted without the need for special tools.

polyurethane bushings are designed to decrease the amount of deflection
in your car's suspension which improves handling, driver feedback, and
tire wear. A premium polyurethane formulation is used, specifically to provide
minimal NVH (noise, vibration, harshness) and increased longevity over
stock rubber bushings.
are produced in one of three durometers:
Unlike other brands using only one urethane for all applications,
Powerflex design engineers choose the correct hardness to allow for the
specific movement or rigidity required for each location while
minimizing unwanted NVH.
(70A): firmer than stock but offering some compliance for
(80A): firmer than stock with less compliance, balancing
NVH and stiffness
- black (95A): very stiff for maximum
preservation of suspension geometry
hardness is standardized per fitment and location,
while select parts are available in an optional stiffer urethane (The
Black Series) for track and autocross performance where NVH is less
important. Consequently, the "Street" kits will contain mostly Purple
some of the individual components may be Yellow (e.g. steering
shaft ) or Black (e.g. drop links). Likewise,
when selecting "Race" kits, most of the bushings will be the harder
durometer, but some of the individual components may be Purple (e.g.
torsion carrier pivots) or
Yellow (e.g. steering shaft).
copper-based grease is supplied with every bushing set. We suggest
using only a copper based grease for lubrication. Bushings will rarely
need re-lubing due to the unique grooves and knurls cast into the
material to hold the lubricant. It is not suggested to use an
"anti-seize" product for lubrication.
a truly engineered product, not just a copy of the stock part in a
different material. Redesigned to address common factory failure parts,
Powerflex bushings allow the articulation required to far outlast the
stock part it is replacing while maintaining control of the movement
for increased performance. Additionally, Powerflex Engineering Line
products for some fitments include unique features like polyurethane
monoballs and offset geometry to provide ultimate performance without
the harshness of a metallic monoball race part. Polyurethane
engine/drivetrain mounts and reinforcements are available for some
fitments to reduce movement for better throttle response and more power
to the wheels.
