4x4 DAMPER SPORT
Specifications
Product Specifications
Lift Up
The ride height can be adjusted by moving the lower spring seat up or down. Its simple structure allows for easier handling.
Standard ride height for 4x4 DAMPER SPORT is set at 40mm (approx. 1.5 inch) higher than the original, to accommodate various driving scenes from streets to off-roading.
Sealed Structure
A New Formula and a New Structure!
Making an Incredibly Low Price a Reality
About the Sealed Structure
The top end of the shell pipe is narrowed, oil and gas are injected, and the whole unit is sealed by crimping the metal.
This new approach massively shortens the production process. As a result, we have succeeded in vastly cutting production cost.
Partial Production Process of 4X4 DAMPER SPORT
Twin-Tube System
Compared to the regular mono-tube system, twin-tube attains longer strokes 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 flexible strokes, you can negotiate gaps and bumps steadily on rough roads, meaning a smooth ride at low speed and stability at high speed.
Hydraulic Bump Stopper (H.B.S.)
H.B.S. improves comfort and durability, even when the vehicle is fully loaded,
as well as off-roading drivability.
How the H.B.S. Mechanism Works
When regular shock absorbers fully stroke, their bump rubbers are compressed. The energy that is generated by that escapes as a repulsive force, which can disturb the vehicle's behavior. Furthermore, repeated full strokes can damage the damper.
In the same situation, 4X4 DAMPER SPORT, featuring H.B.S., internally converts the impact of the stroke to thermal energy (heat) and absorb it, strongly reducing the impact that disturbs the vehicle's behavior. With less damage to the dampers, H.B.S. also contributes to their durability.
Driving over a bump, the vehicle jolts and bounces. It takes a while to regain control.
The vehicle smoothly processes the impact, does not bounce, and its behavior swiftly stabilizes.
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.
Swiftly absorbing the impact of big jumps, H.B.S. effects a steady vehicle.
Use OE Mounts
4X4 DAMPER SPORT uses the vehicle's original upper mounts (not included in our product kit).
High Durability and Reliablility
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 extreme resiliency.
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
Exhibiting a stable viscosity in a broad temperature range, the high-performance damper oil sustains smooth strokes and a reliable damping force under all kinds of circumstances. It has excellent anti-foaming properties that protect it from cavitation (bubble-forming), and is resistant to overheating, so that it works noiselessly even on rough roads. The damper oil keeps up its superior performance long-term, because it is also resistant to deterioration over time.
Rust-Proofing
TEIN-Green Powder Coating
A bright TEIN-green powder paint is used on the shock absorber's shell case. Our powder coating technique produces an extremely strong and durable barrier. No harmful organic solvents are used, for minimal pollution.
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.
(Japanese patent number 4347712)
Damping Force Adjustable
4X4 DAMPER SPORT 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.
The above are examples; actual settings vary according to the vehicle's circumstances.
