EnduraPro SP KIT and EnduraPro PLUS SP KIT are high-performance OE-shape shock absorber kits. Designed to use with the vehicles 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, exclusively-designed low-down springs included in the SP KIT allow for lowered ride height while also improving the ride quality and the cornering performance.;Sold as a Complete Set;EnduraPro SP KIT and EnduraPro PLUS SP KIT are sold as a set for 1 car, combining EnduraPro / EnduraPro PLUS dampers with the matching low-down springs, to offer a complete entry model damper kit at a very affordable price.;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.;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 vehicles 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 vehicles 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.;ENDUREPRO SP PLUS ADDS THE FOLLOWING FEATURES;Damping Force Adjustment;EnduraPro SP 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 SP PLUS is compatible with the EDFC Series, which offer easy damping force adjustment from the drivers seat.
