For those aiming to achieve competition setup chasing 1/1000th of a second advantage. Designed for professionals, Designed Competion Victories

Motorsports, Competition Tire matched damper and spring tuning for high load and exacting calibrations.

For competition users who are more dedicated for racing only automobile tuning, and designed for very specific parameters of raceway use.

For absolute and critical professional racing environments

Features the ability to cater to fine level adjustments in absolute precision and with isolated parameters for racing.

Ability to adapt to a huge range of spring rates

3 Way, 24 Step High Speed Compression, 24 Step Low Speed Compression, and 24 Step Rebound Rate adjustments

Based on our reliable in-house designed professional mono-tube system, a separate reservoir tank is added to increase fluid/gas capacities for more stability, and consistency.

For Double-Whishbone applications, anodized CNC machined, high-tensile alloy case is supplied.

Mono-Tube Damper System
By using a very high quality, high capacity valve system, the system will allow efffective damping of low to high rate of motions effectively. Since the mono-tube design allows shell case walls can dissipate heat directly, heat related inconsistencies are eliminated.

Separate Reservoir System
By addition of a reservoir, the fluid and gas temperature can be much more stable with increased volume and isolation from shock body. And overall performance consistency can be enhanced from this increased capacity.

24 Steps x 3 Way Damper Adjustments
24 Ways with separated controls of Rebound, High Speed Compression, and Low Speed Compresson offers nearly infinite control of ranges and parameters for any build, tune focus, and with ultra-precise performance goals realized.

Separate Height Adjustment Bracket
Fine tuning of ride height is possible without alteration of spring preload or stroke range changes. Assuring full and ideal stroke performance, even with lowest of ride height settings.

NEW Cusco Original "Blue Spring"
Double Shot Peened and designed with anti-sagging manufacturing methods, the Cusco Blue Springs are uniquely precise and consistent, offering a much more acccurate tuning goals.

Upper Mounts
"Strut Type applications are packaged with adjustable camber, rigid upper mounts.
For others a more street oriented fixed hard rubber bushings are supplied. "
For applications without upper mounts, a center-lock rigid upper can be optional.
Also for exacting needs of motorsports, an adjustable camber and caster control upper is also optional.

Ram Type Damper Layout (Inverted Piston)
For strut type applications, the front suspension feature an inverted ram layout, positioning the case and piston inverted and allowing the case to become the structrural support. This design like many high-end cars, allow for a huge improvement in rigidity and precision under high loads of braking and cornering.
This design also acts to better cooling, and reduction in unsprung weight for suspension components.

Designed for Circuit Specification Tires and Racing Tires
Optional Spring Rates at the time of ordering
Anti-Corrosion Treatments that survive 500 hours of salt spray testing for various components.
Rebuilding and Retuning are possible through select qualified shops
Manufacturing is done in Japan with full compliance and exceeding ISO9001 and ASEA standards.
