Genuine Ralliart Pillow-Ball Bushing Front Lower Arm Rear EVO 7/8/9 RA519675K1

Firstly, Buy Ralliart Pillow-Ball Bushing Front Lower Arm Rear EVO 7 8 9 RA519675K1. The Genuine Ralliart Pillow-Ball Bushing Front Lower Arm Rear EVO 7/8/9 is a performance-oriented suspension component designed for the front lower control arm of the Mitsubishi Lancer Evolution VII, VIII, and IX. Ralliart part number RA519675K1 is the rear-position bushing for the front lower arm and is associated with Mitsubishi part number MN580142. It uses a pillow-ball design intended to provide more direct suspension movement and control than a conventional compliant rubber bushing.

The front lower arm rear bushing is an important suspension mounting point because it controls how the lower arm is located relative to the chassis. The Ralliart pillow-ball design reduces the compliance normally introduced by a conventional rubber mounting, making it particularly relevant for enthusiasts building an Evo 7, Evo 8, or Evo 9 for sharper handling, spirited road driving, or motorsport use.

Genuine Ralliart Front Lower Arm Rear Pillow-Ball Bushing

Ralliart developed a range of competition-oriented reinforced suspension bushings for Mitsubishi performance vehicles. RA519675K1 is specifically identified as the front lower arm rear bushing for the CT9A platform. Historical Ralliart parts documentation lists it as a Hs90 bushing and specifies two pieces for the vehicle.

Unlike a basic replacement rubber bushing, a pillow-ball mounting uses a spherical bearing arrangement to allow controlled articulation of the suspension arm. Mitsubishi’s Evo 8 technical documentation also identifies pillow-ball bushings within the front suspension lower-arm assembly.

This makes the Ralliart component particularly relevant when refreshing the front suspension of an older Evo where the original bushings have become worn, deteriorated, or excessively compliant.

Why Choose RA519675K1?

Firstly, the Genuine Ralliart Pillow-Ball Bushing Front Lower Arm Rear EVO 7/8/9 is designed specifically for the CT9A front lower arm application. Using the correct application-specific component avoids trying to adapt a generic suspension bushing to the original arm.

Secondly, the pillow-ball construction is intended to provide a more direct connection between the suspension arm and chassis. Reduced bushing compliance can help the suspension respond more directly to steering and road inputs.

Thirdly, Ralliart’s performance suspension components were developed around Mitsubishi’s Evolution platform, making this part particularly appropriate for enthusiasts who want to retain a period-correct Ralliart performance setup.

Evo 7, Evo 8 and Evo 9 Application

RA519675K1 is associated with the CT9A Mitsubishi Lancer Evolution VII, VIII, and IX platform. Historical Ralliart documentation specifically lists RA519675K1 as the front lower arm rear bushing for the Evo VII, while other Ralliart application references cover the CT9A Evo 7–9 suspension range.

Applications include:

• Mitsubishi Lancer Evolution VII
• Mitsubishi Lancer Evolution VIII
• Mitsubishi Lancer Evolution IX
• CT9A chassis
• Front lower control arm
• Rear mounting position of the front lower arm

Because individual markets, model years, and suspension configurations can differ, verify the chassis and existing control-arm configuration before ordering.

Front Lower Arm Rear Position

It is important to distinguish RA519675K1 from other Ralliart front lower-arm bushings.

The CT9A front lower arm uses separate front and rear mounting locations. Ralliart part RA554817K1 is identified as the front-position front lower arm bushing, while RA519675K1 is the rear-position pillow-ball bushing. Historical Ralliart documentation lists the two parts separately.

Therefore, if you are refreshing both mounting positions, make sure you order the correct bushing for each location rather than assuming the two parts are interchangeable.

Suspension Benefits and Performance Characteristics

A pillow-ball suspension mounting is designed to minimize unwanted movement caused by soft bushing deformation. This can make suspension response feel more immediate, particularly during steering, braking, acceleration, and cornering.

Potential benefits include:

• More direct suspension response
• Reduced compliance at the lower-arm mounting point
• Improved control-arm location
• Sharper steering response
• More consistent suspension movement
• Performance-oriented suspension feel
• Ralliart-style suspension specification
• Suitable for road and competition-oriented Evo builds

The exact driving characteristics will depend on the complete suspension setup, including springs, dampers, alignment, tires, control arms, and other bushings.

Ideal for Evo Suspension Restoration and Performance Builds

RA519675K1 can be particularly useful when rebuilding an Evo 7, 8, or 9 front suspension. Older CT9A vehicles can have significant mileage, and suspension bushings are wear items that can eventually require replacement.

This Ralliart component is suitable for projects such as:

• Evo 7 suspension restoration
• Evo 8 suspension refresh
• Evo 9 handling upgrades
• Ralliart-style builds
• Track-oriented Evo projects
• Autocross and motorsport preparation
• Front lower-arm refurbishment
• Replacement of worn suspension bushings
• Period-correct Ralliart builds

When replacing suspension bushings, inspect the control arms, ball joints, fasteners, and surrounding mounting points at the same time. Any damaged or worn components should be addressed before final alignment.

Installation Considerations

Installation of a pillow-ball bushing generally requires suitable suspension-bushing removal and installation equipment. The Ralliart product listing specifically notes that specialized equipment may be required for replacement.

The control arm should be removed and inspected before installation. The new bushing should be installed in the correct orientation and position, with final fastener tightening performed according to the applicable Mitsubishi service specifications.

After replacing front lower-arm bushings, a professional wheel alignment is recommended. Changes in bushing condition or suspension geometry can affect alignment settings, so checking caster, camber, toe, and steering position is an important final step.

Ralliart Pillow-Ball Bushing vs. Conventional Rubber Bushings

A conventional rubber bushing is designed to provide isolation and compliance while allowing controlled suspension movement. A pillow-ball design takes a different approach by allowing articulation through a spherical bearing.

For an enthusiast focused on a more direct suspension response, the Ralliart pillow-ball configuration can provide a different driving feel from a softer rubber replacement. However, increased mechanical directness can also transmit more road vibration, impact, noise, or harshness into the vehicle depending on the rest of the suspension setup.

A performance bushing should therefore be selected according to how the Evo is used rather than simply choosing the stiffest available component.
