High Capacity Mono-Tube System for highest grade performance in coilover systems with 24-step damper adjustments.
TN Series offer twin needle valving to allow separate tuning of both rebound and compression in separate dial control, offering even wider range of precision setup
With performance potential taken from our SPORT TN_R model, the Sport TN_S has been optimized to accommodate street use with alternate and ideal spring rate and shock valve retune.
Designed for use with performance radial tires for street use, and optimization for daily use with milder tires while seeking performance to the highest levels.
Separate 24 Step Compression and Rebound adjsutments allow for a precise control and setup for the most demanding users. Allows for fine levels of tuning to compensate for braking, turn-in, lateral loads, corner exit, and stability under over and understeer for those who can translate this into subtle differences in driving precision.
Tuned for the street, depending on the model, upper mounts are compliant sports rubber design, for the rear. Double wishbone suspension systems are featured with both front and rear rubber mount.
Large capacity pistons provide the highest level of control between damper requirement of various load speeds, registering a superb range of consistent performance and stability of comfort.
Compression 24 Step, Rebound 24 Step, Two-Way Separated Adjustment
Our new "Twin Needle System" uses a newly developed in-house system of separate compression / rebound fine tuning via rebound-specific valve body fluid path, hence allowing separation of controls as never been achieved before.
With combination of 24 steps in both directions, a total of 576 different settings are possible
A new potential of adjusting for even tiny parameters required to compensate for changes in internal fluid temperatures, and wear over time, as well as other veicle specific areas.
Rebound with blue dial, compression with red dial. Both adjustment on one end of the damper system hence needing no tools or cumbersome ways to modify the car in any way.
Separation of two loads at the core means there is more specific and uni-directional load on each valve channel, and therefore a more precise isolated control and minimal variances in settings are achived.
A linear handing, positive grip, and traction are further enhanced over wider range of loads and speeds.
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 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 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 Street Legal High-Performance Radial 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.
