KSport Rally Spec AR Coilovers

2004–2006 Scion xB

CSC010-AR

Overview:

The KSport Rally Spec AR Coilovers are engineered specifically for the 2004 to 2006 Scion xB, delivering a suspension solution tailored for asphalt rally competition. Designed to enhance handling precision and durability under demanding conditions, these coilovers offer extended stroke and heavy-duty internals to withstand the rigors of aggressive driving. With simultaneous compression and rebound adjustment, drivers can fine-tune their suspension setup to balance comfort and performance, making these coilovers ideal for enthusiasts seeking improved control without sacrificing ride quality.

Whether you are competing in rally events or looking to upgrade your xB’s suspension for spirited street driving, the Rally Spec AR coilovers provide a robust and adjustable platform that maintains OEM suspension geometry while allowing up to 3 inches of adjustable ride height.

Key Features:

The KSport Rally Spec AR Coilovers combine advanced technology and thoughtful design to deliver superior performance and reliability. Key features include:

• Specially designed springs optimized for rally conditions with 7.5kg (420 lbs) front and 3kg (168 lbs) rear spring rates
• Extended piston stroke for increased suspension travel and improved handling on rough surfaces
• Reinforced heavy-duty internals built to endure extreme track and rally conditions
• 36-way adjustable damping that simultaneously adjusts compression and rebound for precise tuning
• Pillow ball top mounts in the front (and rear reuse of OEM mounts) for enhanced steering response and suspension geometry retention
• Camber adjustability integrated into pillow ball mounts, eliminating the need for separate camber kits
• Adjustable lower mounts allowing ride height changes up to 3 inches without sacrificing suspension travel
• Monotube high-pressure damper design for superior heat dissipation and reduced aeration compared to twin-tube shocks
• Lightweight and corrosion-resistant 6061 billet aluminum components with T6 heat treatment for increased hardness
• Electroplated steel shock bodies for enhanced rust and corrosion protection

Construction & Design:

The Rally Spec AR Coilovers are crafted from premium materials to ensure durability and performance longevity. The majority of the coilover components, including mounts and adjusters, are machined from 6061 billet aluminum treated with T6 heat processing to increase strength and hardness while minimizing weight. The shock body is constructed from steel and electroplated with zinc, providing excellent resistance to rust and corrosion, essential for rally environments where exposure to moisture and debris is common.

The monotube damper design separates oil and gas within the cylinder, allowing for more consistent damping performance, better heat dissipation, and reduced cavitation compared to traditional twin-tube shocks. This advanced engineering results in a smoother, more controlled ride and improved handling response under demanding conditions.

Installation & Fitment:

Designed as a direct fit for the 2004–2006 Scion xB, the KSport Rally Spec AR Coilovers install using existing mounting points with minimal modifications required. Front pillow ball mounts replace factory mounts to maintain suspension geometry and provide adjustable camber settings, while the rear reuses OEM mounts for a straightforward installation. The adjustable lower mounts allow for precise ride height tuning without compromising suspension travel, making it easy to comply with rally event regulations or personal preferences.

What's Included:

• Front and rear coilover assemblies with springs pre-installed
• Front pillow ball top mounts with camber adjustment
• Adjustable lower mounts for ride height tuning
• All necessary hardware for installation
• Detailed installation instructions

Ideal For:

The KSport Rally Spec AR Coilovers are ideal for Scion xB owners who participate in asphalt rally competitions or seek a high-performance suspension upgrade that balances durability, adjustability, and ride quality. Enthusiasts looking to improve handling precision, suspension travel, and driver feedback will benefit from this coilover system’s advanced features and robust construction. Additionally, those requiring compliance with rally ride height regulations will appreciate the adjustable height capability up to 3 inches below OEM levels.
