Steering damper for Suzuki Samurai
Steering damper and reinforced with 50 mm body and 16 mm oversized stem.
The shock absorber can be adjusted and overhauled in all its parts.
The HM4X4 steering damper has the following technical specifications:
- Air Dried pressurization to improve calibration consistency even in extreme conditions.
- T.I.G. for maximum resistance and a refined aesthetic;
- double tube in mechanical steel internally lapped, painted with epoxy powders and phosphated to prevent corrosion, the outer tube has a diameter of 50mm and a thickness of 2mm to withstand impacts, in case the body is dented the shock absorber will continue to function normally;
- 16 mm steel rod coated in hard chrome CrVI free with tolerance according to EN ISO 286-2
- polyurethane bushings very resistant to deformation and wear, they are molded with 80 shore thermoplastic polyurethane specific for automotive use, resistant to grease, oil and fuel;
- sintered internal components for maximum wear-free calibration control;
- graphite teflon sealing band to improve suspension smoothness, compared to cast iron bands they are much quieter.
- double bump stop in polyurethane and steel to stop the extension stroke in a controlled way and not to burden the attachments to the frame and bridges;
- ROTHEN shock absorber oil designed specifically for off-road use with a high viscosity index that guarantees regular calibration up to 200 °C, essential for intense use such as races or raids in the desert;
- double adjustment of rebound and compression settings, both at high and low speeds with preloaded travel reed valves with star springs in compression and helical spring in rebound;
- double seal with o-ring and oil seal with metal base, the high quality of the closure allows not to use the fork protectors that in the long run create accumulation of dirt and damage the shock absorber, any debris that settles on the stem is cleaned by the double lip of the metal oil seal;
- calibration on a 10-speed test bench, from 5 to 500 m/s to have perfect calibration in all conditions.
The overhaul of the HM4X4 shock absorbers is guaranteed at a cost of 40.00 euros each for the entire life of the shock absorber.
AIR DRYED pressurization is an innovative two-stage pressurization technique. It allows to pressurize the shock absorber with inert gas, after having created a high vacuum, completely extracting air and humidity from its interior. This allows to minimize the phenomena of oil emulsion and the creation of rust that humidity inevitably creates inside a non-pressurized shock absorber.
In addition to making the shock absorber more performing, the air dried pressurization considerably extends the life of the shock absorber and the constancy of the calibration.
