Tein EnduraPro Plus (05-07 STI)

EnduraPro are high-performance OE-shape shock absorbers. Designed to use with the vehicle's original (OE) spring and upper mount, their lower spring seat is shaped identical to the OE shock absorber. In addition to replacing worn or leaking OE dampers, these products are excellent to improve specs like ride quality or handling without changing your ride height. You can also use them with TEIN lowering springs.

Available Per Piece
Because EnduraPro and EnduraPro PLUS can be purchased per 1 shock absorber, you can limit the cost for replacing worn or damaged dampers.

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.

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.

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.

Hydraulic Bump Stopper (HBS)
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.

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.

Damping Force Adjustment
EnduraPro PLUS 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.

EDFC Compatibility
EnduraPro PLUS is compatible with the EDFC Series, which offer easy damping force adjustment from the driver's seat.
