High Durability and Superior Quality

Sealed Structure

A "sealed structure", attained by a new production formula,

combines high quality with reduced cost.

'Repairable' Unit of Parts → 'Sealed Structure' Fixed Unit

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 EnduraPro and EnduraPro PLUS

Partial Production Process

High Strength and Durability

Fortified Installation Points

Example: Thickness comparison of front installation bracket for Honda Jazz/Fit GP5

: OE

: EnduraPro

For strut-type suspensions a thickness increase improves the strength and durability of the bracket attaching to the vehicle (steering knuckle) compared to OE shock absorbers. This higher rigidity of the knuckle's support also improves steering feel and makes the ride feel more stable. Please note that the thickness increase varies per vehicle model.

Fortified Shell Case with Large Oil Capacity

The shell case, the key part of the shock absorber, is made of a high-strength material with tensile strength around 150% of the OE shell case. Weight increase is curbed by keeping the thickness of the cylinder wall the same. A bigger shell case diameter expands its oil capacity, for improved durability as well as a long-term stable damping force performance.

Example: Comparisons for the Honda Jazz/Fit (GP5)

Shell Case Tensile Strength

	OE	EnduraPro
Tensile Strength (Mpa)	340	510

Shell Case Diameter

	OE	EnduraPro
Front Shock Absorbers	φ45	φ55
Rear Shock Absorbers	φ45	φ50.8

Please note: tensile strength and diameter of shell case vary per vehicle model.

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.

Rustproof Surface Treatment

The shell case's bright TEIN-green powder paint coating excels in strength and durability, while our coating technique is eco-friendly and without organic solvents. After pre-treatment, TEIN's patented 2-Layer, 1-Bake powder coating method with corrosion-proofing paint is used for superior durability and rust protection.*

Outstandingly corrosion-resistant, EnduraPro and EnduraPro PLUS can safely be used in regions with heavy snowfall or coastal areas, etc.

Hydraulic Bump Stopper (H.B.S.)

More comfort and higher durability at maximum passenger and cargo load.

How the H.B.S. Mechanism Works

Regular Shock Absorbers / Shock Absovers with H.B.S.

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 EnduraPro and EnduraPro PLUS, featuring H.B.S., internally convert 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.
