Whiteline Front Control Arm Lower Inner Rear Bushing Kit EVO 7/8/9 KCA469

Firstly, Buy Whiteline Front Control Arm Lower Inner Rear Bushing EVO 7 8 9 KCA469. The Whiteline Front Control Arm Lower Inner Rear Bushing Kit EVO 7/8/9 is a performance suspension upgrade designed for the Mitsubishi Lancer Evolution VII, VIII, and IX. Whiteline part number KCA469 is a dual-offset front lower control arm inner rear bushing kit engineered to increase static caster, improve front-end geometry, and provide more consistent suspension control. Whiteline specifies this kit as a Performance Alignment component that adds approximately +0.5 degrees of caster.

The front lower control arm is a critical part of the Evo’s front suspension. Its bushings influence how the control arm moves under braking, acceleration, steering, and cornering loads. As original rubber bushings age, excessive compliance can allow unwanted movement and alignment changes. KCA469 is designed to reduce this unwanted deflection while introducing a controlled caster increase.

For Evo 7, Evo 8, and Evo 9 owners looking to refresh worn suspension components or improve front-end response, the Whiteline KCA469 provides a purpose-built solution without requiring a completely different control arm assembly.

Whiteline KCA469 Front Lower Control Arm Inner Rear Bushing

The Whiteline Front Control Arm Lower Inner Rear Bushing Kit EVO 7/8/9 uses a dual-offset configuration. Whiteline describes its caster kits as being designed to improve cornering grip and straight-line stability while providing greater steering feel, steering weight, and precision through increased static caster and dynamic negative camber gain.

The kit is specifically positioned at the inner rear mounting location of the front lower control arm. It should not be confused with Whiteline’s separate front lower control arm inner front bushing kit, which uses a different part number.

This makes KCA469 a useful choice when you want to address the rear inner bushing location while also making a measurable geometry change to the front suspension.

Why Choose Whiteline KCA469?

Firstly, KCA469 is designed specifically around the Evo 7/8/9 front suspension geometry. Rather than simply replacing an OE bushing with a generic component, Whiteline uses the bushing design to introduce additional caster and improve suspension geometry.

Secondly, the dual-offset configuration provides an alignment benefit. Whiteline specifies approximately +0.5° caster, which can increase steering feel and help maintain tire contact during cornering.

Thirdly, replacing worn or excessively compliant control-arm bushings can help reduce unwanted alignment movement under load. Whiteline specifically states that the KCA469 design provides improved braking performance and less under-load alignment change.

These characteristics make the KCA469 suitable for street-driven Evo builds, performance suspension setups, and vehicles used for spirited driving or track events.

EVO 7, EVO 8 & EVO 9 Fitment

Whiteline lists KCA469 for the Mitsubishi Lancer Evolution 7, 8, and 9. Evo-specific retailers also identify the part for the 2001–2006 Evolution VII, VIII, and IX platform.

Compatible applications include:

• Mitsubishi Lancer Evolution VII
• Mitsubishi Lancer Evolution VIII
• Mitsubishi Lancer Evolution IX
• CT9A platform
• Front lower control arm
• Inner rear control-arm mounting position

Some North American catalogs display narrower year ranges based on market-specific vehicle listings, so checking the exact chassis and control-arm configuration is recommended before ordering.

Dual-Offset Design and Caster Improvement

One of the defining features of KCA469 is its dual-offset bushing design.

Instead of functioning only as a replacement for the original suspension bushing, the offset design changes the position of the control arm within its mounting location. Whiteline specifies the resulting alignment change as approximately +0.5° caster.

Additional caster can influence steering response, straight-line stability, and front tire contact during steering. Whiteline also describes the KCA469 as helping produce dynamic negative camber gain, which can help maintain tire contact during cornering.

Actual alignment results can vary depending on the vehicle’s suspension configuration, ride height, existing alignment settings, and other aftermarket components.

Performance Benefits

Upgrading the front lower control arm inner rear bushings can provide several benefits for an Evo suspension system.

Potential advantages include:

• Increased static caster
• Approximately +0.5° caster change
• Improved steering feel
• More precise front-end response
• Reduced control-arm deflection
• Improved chassis control
• Better front-end grip
• More consistent braking behavior
• Reduced alignment change under load
• Improved cornering response
• Synthetic elastomer construction
• Dual-offset performance alignment design

Whiteline identifies KCA469 as a performance alignment component intended to maximize tire contact with the road and improve cornering and grip.

High-Quality Suspension Bushing Construction

Whiteline’s control-arm bushing range uses synthetic elastomer construction designed to provide greater durability and performance compared with aging factory rubber bushings. Retailer specifications for KCA469 identify the bushings as a high-quality synthetic elastomer design.

A firmer suspension bushing can reduce unwanted movement, but it can also change the overall NVH characteristics of the vehicle. The final driving feel will depend on the rest of the suspension system, including springs, dampers, tires, sway bars, and other bushings.

For a performance-oriented Evo build, replacing several worn suspension bushings together can also help create a more consistent overall suspension response.

What’s Included with KCA469?

Whiteline specifies the KCA469 kit contents as:

• 2 × shell bushings
• 2 × bearings
• 4 × washers

Whiteline lists 1 kit required per vehicle.

This is important when planning a suspension rebuild because KCA469 is sold as a complete application-specific kit rather than as a single individual bushing.

Installation and Alignment

Whiteline lists an approximate installation time of 2.5 hours and recommends a suspension specialist for installation. A wheel alignment is required after installation.

Because KCA469 changes front suspension geometry by adding caster, alignment should be treated as an essential part of the installation rather than an optional adjustment.

During installation, inspect the front lower control arms, mounting hardware, ball joints, and surrounding chassis mounting points. If the vehicle has been modified or lowered, the existing suspension geometry should also be evaluated before final alignment.

After installation, the alignment should be checked using the vehicle’s intended street or track specifications.

Ideal for Evo Street and Performance Builds

The Whiteline KCA469 is well suited to several types of Mitsubishi Evolution projects, including:

• Evo 7 suspension refreshes
• Evo 8 handling upgrades
• Evo 9 performance builds
• Street-performance vehicles
• Track-day Evo builds
• Autocross vehicles
• Suspension restoration projects
• Alignment-focused builds
• Vehicles with worn original bushings
• Enthusiasts seeking additional front-end caster

For a complete front suspension refresh, KCA469 can also be paired with the appropriate Whiteline front-position lower control-arm bushing and other suspension components, provided the parts are confirmed for the specific vehicle.
