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

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 costs.

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 a tensile strength of 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 and long-term stable damping force performance.

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 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 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.

Hydraulic Bump Stopper

When regular shock absorbers fully stroke, their bump rubbers are compressed. The energy 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.
