Control Arms with Fitting Position Rear for 2015 Subaru Impreza I Sport

Control arms are the platform-specific front and rear suspension arm assemblies and geometry correction kits used to replace worn, damaged or geometry-limited factory control arms across passenger, 4WD and truck platforms. Each control arm connects the wheel hub carrier or knuckle to the chassis through inner pivot bushings and an outer ball joint, defining the path through which the wheel travels as the suspension cycles. The condition and specification of the arm, its inner bushings and its ball joint directly affect suspension geometry, wheel alignment, steering feel, handling precision and tire wear consistency throughout the Subaru Impreza's service life.

The Subaru Impreza range includes OEM-specification lower and upper control arm assemblies for direct factory replacement, as well as OEM+ enhanced assemblies that provide additional geometry correction as a standard upgrade. Heavy-duty fixed and adjustable front lower and upper control arm sets are available for performance and off-road applications. Geometry-optimised upper control arm kits, including fixed offset designs, are engineered to restore correct caster and camber on lifted vehicles. Alloy lower control arm sets with built-in geometry correction are also available, along with rear trailing arm assemblies, complete sets, and ball joint dust boot kits for both 2WD and 4WD applications. Installation guides are available for most products.

Why Upgrade Subaru Impreza Suspension?

Factory control arms are designed to operate within the Subaru Impreza's standard suspension geometry at stock ride height. On lifted trucks and off-road vehicles, raising the suspension displaces the inner and outer pivot points of the control arm beyond their designed operating range, introducing geometry errors at full droop and bump that cannot be corrected through alignment adjustments alone. On high-mileage vehicles, factory arms with worn or deformed inner bushings and degraded ball joint boots allow increased play and compliance that degrades alignment retention, steering response and handling precision with every mile driven.

Replacing factory arms with correctly specified OEM or OEM+ assemblies restores the designed geometry and component condition for everyday and performance-driving platforms. For lifted applications, Subaru Impreza geometry-optimized or fixed offset upper control arm kits restore the correct caster and camber angles at the new ride height, eliminating the bump steer, caster error and uneven tire wear that lifted factory geometry introduces and ensuring the full range of suspension travel operates within correct alignment parameters.

• Subaru Impreza HD Fixed Front Lower Control Arm Sets: Heavy duty fixed-geometry front lower control arm sets for applicable 4WD and off-road platforms requiring increased arm strength over factory specification.
• Subaru Impreza HD Adjustable Front Lower Control Arm Sets: Heavy duty adjustable front lower control arm sets allowing controlled geometry adjustment at the lower arm pivot on applicable lifted and performance 4WD platforms.
• Subaru Impreza HD Adjustable Front Upper Control Arm Sets: Heavy duty adjustable front upper control arm sets for applicable lifted and performance 4WD platforms requiring upper arm adjustment to restore caster and camber geometry.
• Subaru Impreza Geometry Optimized Front Upper Control Arm Kits: Restores correct caster and camber geometry on applicable lifted truck platforms at lift ranges up to the specified maximum, correcting the geometry errors introduced by factory arms at increased ride heights.
• Subaru Impreza Fixed Offset Camber and Caster Correcting Upper Control Arm Sets: Front upper control arm sets with a fixed offset geometry correction engineered to restore correct alignment angles on applicable lifted truck platforms.
• Subaru Impreza Alloy Front Lower Control Arm Sets: Alloy front lower control arm sets providing additional positive caster and negative camber correction on applicable platforms for improved steering and handling geometry.
• Subaru Impreza Rear Trailing Arm Assemblies and Sets: Individual and complete rear trailing arm replacements and adjustable sets for applicable passenger and 4WD platforms requiring rear arm replacement or geometry correction.
• Subaru Impreza Ball Joint Dust Boot Kits: Polyurethane replacement dust boot kits for front ball joints on applicable 2WD and 4WD platforms, protecting the ball joint from contamination and extending service life.

Why Purchase Subaru Impreza Control Arms?

Control arm replacement addresses a structural-level cause of suspension degradation that cannot be resolved through bushing renewal or alignment adjustment alone when the arm itself is worn, bent or geometry-limited by ride height. OEM and OEM+ replacement arms restore the correct structural and geometric baseline for everyday driving platforms. For lifted trucks, geometry-optimized and fixed offset upper arms deliver correct caster and camber angles at the lifted height, eliminating the alignment errors, uneven tire wear and handling inconsistencies that lifted factory geometry introduces and ensuring the suspension operates correctly through its full travel range at the new ride height.

For shops completing Subaru Impreza suspension lifts and off-road builds, providing the correct upper control arm kit as part of the lift installation ensures every geometry variable is addressed at the time of the build, rather than after alignment errors and tire wear have already developed.

Installation and Support

Control arm assemblies and kits are designed for installation at the front lower, front upper and rear trailing arm positions. Installation times range from half an hour for ball joint dust boot kits to two to three hours for full arm assemblies and sets. Installation guides are available across most products. For additional technical assistance, a dedicated support team is available to help confirm correct product selection, geometry correction specification and fitment for the Subaru Impreza, lift height and suspension configuration.

Repair and Upgrade

Control arms are manufactured from high-strength steel and alloy materials engineered to withstand the structural loads, road shock and environmental exposure that front and rear suspension arm positions are subject to in everyday, performance and off-road use. Geometry-optimized and fixed offset upper arm kits are precision-engineered to the correct offset for the applicable platform and lift range, ensuring accurate caster and camber correction that can be set and retained through the full suspension travel arc. Polyurethane Subaru Impreza inner bushings installed in applicable arm assemblies resist deflection and contamination more effectively than factory rubber, maintaining geometry retention for longer under demanding conditions.

Who Subaru Impreza Control Arms Are For

Subaru Impreza Control arms are a practical solution for:

• Workshop technicians installing lift kits and correcting suspension geometry on 4WD trucks and SUVs.
• Off-road and overlanding drivers upgrading to heavy-duty control arms for strength, durability and improved handling.
• Mechanics and DIY users replacing worn front lower control arm assemblies on passenger and performance vehicles.
• Lifted vehicle owners experiencing uneven tire wear or handling issues due to incorrect geometry.
• Vehicles needing ball joint dust boot replacement to protect and extend component life.

The right control arm kit restores correct Subaru Impreza suspension geometry, eliminates arm-induced handling degradation and alignment error, and delivers precise, stable and consistent suspension performance through every mile and every terrain condition.
