EnduraPro and EnduraPro PLUS are high-performance OE-shape shock absorbers, made from high strength steel and, uniquely at this price point, featuring Hydraulic Bump Stops.
EnduraPro and EnduraPro PLUS 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 low down springs.
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.
High Strength and Durability - Fortified Installation Points
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.
High-Performance Damper Oil
An essential component of a quality damper - this oil exhibits 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
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.

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.
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.
