THE ROAD TO
WHITELINE PLUS The use of polyurethane in
automotive suspension bushings dates back to the early
1970s when race car enthusiasts looked for improved
handling and suspension performance without having to
resort to solid pivot points and connections.
Traditionally, polyurethane bushings and mounts were
made from very hard urethane compounds exceeding 100 on
the durometer scale; where rubber was much softer and
measured less than 58 on the durometer scale. The main
reason for the extreme hardness was the use of low grade
polyurethanes. In order to achieve abrasion
resistance, tearing and compression set, the
polyurethane needed to be very hard. The second reason
for this hardness was how the component was designed and
manufactured. While high performance polyurethanes were
available they were both very expensive and required
complex machinery in order to process, mix and cast the
component. Few customers would pay for the added
expense; especially when the automotive performance
aftermarket was selling products at a third of the cost.
After extensive development and testing of materials
that would offer strength and durability, geometry
retention and memory without the harshness, WHITELINE
created a progressive, long-chain polymer compound
incorporating polyurethane constituents, which deliver
the combined physical advantages of a solid bushing,
with the extreme flexibility characteristics of rubber.
That range of product is known as WHITELINE PLUS and
delivers LOW SPEED RIDE QUALITY, HIGH SPEED CHASSIS
CONTROL Whiteline Plus polyurethanes provide the
softness needed for low vibration, noise and harshness
characteristics, while displaying extreme abrasion, tear
and cut resistance, and near-zero compression set at
lower durometer reading of 70-80. In addition, these
performance polyurethanes allowed the polymer chains to
be bonded directly to the metal shell, which provided a
method of flow control giving the bushing the
characteristics of soft ride while on smooth roads, and
when under cornering pressure caused the bushing to
become firmer for improved suspension performance.
WHITELINE has engineered a wide range of products to
cover the common passenger, commercial and 4x4 markets
and will continue to grow the range to service new
models and escalating demand. WHITELINE PLUS has been
developed with a ‘NO COMPROMISE’ objective. SERVICING
It provides the reliability, durability, added safety
and ride quality characteristics for everyday vehicles
and servicing. PERFORMANCE
The road holding stability, handling and abrasive
resistence for performance and 4x4 vehicles.
RESTORATION
The neutral (black) appearance for restorers and racers.
PROGRESSIVE BLACK POLYURETHANE BUSHINGS - FEATURES AND
BENEFITS Key Benefits of WHITELINE PLUS
polyurethane bushings:
- The quality of ride of rubber, with the
performance of solid links.
- Long lasting durability.
- Resistant to chemicals, oils and weathering.
- Enhanced handling, steering response and road
holding stability.
- Increased braking capacities and positive brake
pedal ‘feel’.
- Wheel alignment rectification and optimisation
using offset and adjustable bushings and arms
Key Feature of WHITELINE PLUS polyurethane
bushings: As a result of extensive domestic and
export research, we identified that primary coloured
bushings had a mixed reception, especially in
motorsport and restoration markets. As a result
range is made black, but not your standard mat
black. A WHITELINE PLUS bushing appears black in
your hand but hold it to the light to witness it’s
translucent feature. FEATURE ADVANTAGE BENEFIT
Progressive No compromise The ride of rubber at low
speed, chassis control of poly at high speeds
Compliance Chassis Control Positive steering feel
and increased braking capacities
Black Neutral Appearance Less offensive than primary
colours ie, red, yellow
Translucency Modern Appeal Differentiation to rubber
and other black poly alternatives
Durability Longer lasting than rubber Reliability,
longer servicing life
WHITELINE PLUS Spring Eye and Shackle Bushings
- Induce free pivot in spring length changes
under bump and droop loading
- Enhance manoeuvrability
- Eliminate pitching (rocking horse ride) in
short wheel based 4WD’s
- Permit camber and spring length change
ultimately reducing axle tramp
WHITELINE PLUS Shock Absorber Bushings
- Eliminate low speed valving lag,
including the use of heavy duty hydraulic
and gas shocks
- Enhance the performance of both new and
used shock absorbers
- Have superior density and linear flow
properties, radically enhancing capacity to
cope with bump and rebound travel
WHITELINE PLUS Steering Rack Bushings
- Exude characteristics that are
chemically resistant to oils, coolants
and solvents
- Enhances the stability of the
steering rack
WHITELINE PLUS Sway Bar Bushings
- Increase bar rates by 10-20%
- Reduce lag in the suspension as
the bar moves
- Pivot at both mounting points,
utilising entire bar length
WHITELINE PLUS Trailing Arm
Bushings
- Permit optimum pinion angle
changes eliminating
differential, tailshaft and/or
gearbox failure
- Eliminate take off and
driveline shudder under heavy
loads
WHITELINE PLUS Radius Rod/
Caster bar Bushings
- Enhance suspension
geometry retention
- Provide ‘crisp’,
responsive handling
- Optimise braking
capacities
- Achieve more positive
caster from shim, eccentric,
offset and turnbuckle
adjustable bushings and arms
WHITELINE PLUS Control
Arm Bushings
- Enhance handling
characteristics
- Provide a better
steering feel and
vehicle stability
- Induce more
responsive braking
- Rectify wheel
alignment settings with
shim, eccentric, offset
and turnbuckle
adjustable bushings and
arms
REPLACEMENT SUSPENSION
ARMS All would
agree that the time &
stress to remove &
replace bushings and
ball joints to
suspension arms is
possibly not worth it.
Making up press tools &
damaging arms are just
two of the problems one
can endure. Why put
yourself through it when
you can purchase
complete arms, fitted
with market leading
WHITELINE PLUS
polyurethane bushings
and premium quality ball
joints.
Research proves by
purchasing complete arms
you can reduce the time
taken to do the job by
up to 70% which means
less stress for the DIY
repairer and greater job
turnover and profit for
fitters/workshops.
CAMBER & CASTER BUSH
KITS WHITELINE
offers a range of
offset, eccentric
adjustable & shim
adjustable bush kits to
rectify or optimise
wheel alignment
settings. Kits have been
developed to target
caster correction or
camber correction in
order to prolong tyre
life and enhance
handling
characteristics.
WHITELINE’s eccentric
adjustable licensed
design allows wheel
aligners to dial in
incremental wheel
alignment settings with
simple hand tools.
WHITELINE’s shim
adjustable kits also
provide incremental
changes based on shim
thickness and the amount
of shims used.
UNIVERSAL SUSPENSION
PRODUCTS Having
trouble trying to find a
product for your
vehicle? Whiteline plus
offers a range of sway
bar, shock absorber and
spring pad bushings in
various shapes and sizes
to get you out of
trouble. Also available
is a our user friendly
BUSH TYPE AND SIZE
REGISTER, which segments
the entire bushing range
into different types,
based on shape, and then
sorts on size from
smallest to largest.
This is a great tool for
those having difficulty
finding any aftermarket
