Hydraulic Bump Stopper (H.B.S.)
In regular shock absorbers, bump rubber is vital to avoid damage from bottoming out. Unfortunately it causes instability, because when a large impact compresses it, energy thus amassed is released upwards.
RX1 however uses the Hydraulic Bump Stopper to convert the impact to thermal energy and absorb it. This strongly reduces the shock, and there's no repulsion force.
The Hydraulic Bump Stopper (H.B.S.) Mechanism
In shock absorbers with inactive or no H.B.S., the operative valve (green) floats, and oil flows freely through the base valve ports. Resistance to the flow from the shim stack then, causes damping force.
Near full compression, when the piston rod strokes beyond a predetermined point, the operative valve is pushed down and activates H.B.S.: the base valve ports are narrowed, blocking the oil flow. This results in high damping force.
A relief valve serves to suppress sudden damping force increase, when the pressure in the cylinder exceeds its regular level.
The setup of the H.B.S. mechanism is optimized per vehicle model, with the right activation point and damping force.
Camber Adjustable Lower Bracket
Lower brackets on strut type suspensions come with camber angle adjustment feature. Camber angle can be adjusted by rotating the eccentric washer 180°. This feature can enable camber angle adjustment, even if it can not be adjusted with the upper mounts.
*Except some models (e.g. strut with insert type brackets)
Full-Length Ride Height Adjustment
Advantage: adjusting ride height has little effect on ride quality.
In addition to combining a low down style with ride comfort, this system offers more setup options for sport driving too.
Twin-Tube System
Compared to the regular mono-tube system, twin-tube attains longer stroke with a smaller repulsive force, resulting in high ride comfort.
Roads may have all sorts of surface conditions. This calls for shock absorbers with ample stroke, that operate smoothly.
Thanks to this unique characteristic, you can negotiate gaps and bumps steadily on rough roads, meaning a smooth ride at low speed and stability at high speed.
Damping Force Adjustment
RX1 features 16-level damping force adjustment, for simultaneous adjustment of compression and rebound.
Modify ride comfort and handling according to your preference, changing the properties of the shock absorber with the adjustment dial.
Mounts Included
An easy-to-install mount, exclusively designed for each vehicle model, is included in the product kit.
For some vehicle models which do not have mount plates, original mounts are used.
We have devised a suitable mount for each vehicle type.
Pillow ball upper mounts for front strut suspensions feature camber adjustment.*
Replacement Service
For this product we offer not overhaul, but a replacement service.
Our replacement service revives your shock absorber, by replacing the main part. It allows you to buy the shock absorber itself without the exterior parts like the upper mount, lower bracket, spring, etc.
Damping Force Modification
This entails changing damping force to suit your driving conditions or preferences, by re-arranging the shock absorbers' internal components.
Stroke Modification
This entails changing the stroking distance to suit your driving conditions or preferences, by e.g. replacing or modifying the shock absorbers' internal components.
Compatible with EDFC Series (Optional)
The EDFC Series offer easy damping force adjustment from the driver's seat.*
High Durability and Reliability
Optimal Dust Boot
Thanks to its smooth compression and high durability, the dust boot guards the piston rod from damage, and keeps foreign material out of the shock absorber.
(Some vehicles use their OE dust boots)
No-Sag Spring
Cold formed with SAE9254 steel (minimum tensile strength 200 kgf/mm2), our springs are outstandingly sag-proof and boast extremely stable quality.
Superior rust protection is ensured with a highly durable powder coating that does not peel or flake. Our high-quality springs can be used without worries, in any conditions.
High-Performance Damper Oil
Since TEIN's damper oil maintains a stable viscosity in a broad temperature range, it sustains smooth strokes and reliable damping force in a variety of circumstances.
Due to excellent anti-foaming properties, it's resistant to cavitation (bubble forming). Since it's strong against heat too, it's suitable for fierce sport driving as well.
Furthermore, the damper oil keeps up its superior performance long-term, because it's resistant to deterioration over time.
Rust-Proofing
Our unique ZTP Coating surface treatment is abrasion resistant against gravel/debris and further enhances rust/corrosion resistance.
With zero claims for stuck parts due to rust in 2,000,000 shock absorbers, TEIN shock absorbers are amazingly rustproof. We're confident of customer satisfaction even in coastal areas or regions with heavy snowfall.
Also, a bright TEIN-green powder paint provides extremely strong and durable barrier, yet this painting technique cuts pollution to a bare minimum with no harmful organic solvents used.
Superior durability and corrosion resistance are achieved by TEIN's patented 2-Layer, 1-Bake powder coating method, which uses 2 layers of anti-rust paint on a blasted surface.
