Pair of rear reinforced eye/pin shock absorbers +2.4" for Mercedes class G, with 60mm pressurized twin-tube body, which can be revised and adjusted according to your needs.
The shock absorber proposed by us, 100% Made in Italy, is built with steel tubes for mechanical use internally lapped and fully galvanized to avoid corrosion.
The bushings are in polyurethane, very resistant to deformation and wear, all components are sintered for maximum calibration control and the seals are in graphite-coated Teflon to improve smoothness and silence.
They are calibrated in compression like the originals to promote comfort, but more braked in rebound to reduce the hopping of the vehicle. This calibration is designed to best adapt to the Italian off-road vehicle and is compatible with any type of set-up, however the desired one can be chosen at no extra cost when ordering.
The shock absorber can be recalibrated and overhauled in every part, in the first year after purchase the recalibration is carried out free of charge in order to adapt the shock absorber to the use you make of the vehicle.
Inside the shock absorber there is a first internal bump stop in extension resistant up to 5000kg and a second polyurethane bump stop that slows down the last 10mm of stroke to avoid excessive stress six supports to the frame, can be used as a travel limit for the axle.
ROTHEN oil with a high viscosity index is used which guarantees the maintenance of the calibration up to 200 °C, therefore these shock absorbers are also suitable for heavy use and raids in the desert.
Each Competition60 shock absorber has the following features:
- T.I.G. for maximum resistance and a refined aesthetic;
- double tube in mechanical steel lapped internally, entirely galvanized with electrolytic galvanization with Iridescent White finish and subsequent passivation with trivalent chromium base with surface hardness 80 HV, the external tube has a diameter of 60 mm and a thickness of 3 mm to resist shocks , should the body be dented, the shock absorber will continue to function normally;
- steel rod Ø20 mm 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 limit switch 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 absorber is guaranteed at a cost of 40.00 euros each.
AIR DRYED pressurization is an innovative two-phase pressurization technique that allows you to pressurize with inert gas after creating a high vacuum by completely extracting air and humidity inside the shock absorber in order to minimize oil emulsion phenomena. and creating the rust that humidity inside a non-pressurized shock inevitably creates. In addition to making the shock absorber more performing, the Air Dryed pressurization considerably extends the duration of the shock absorber over time and guarantees constant calibration even after years of use.
TECHNICAL SPECIFICATIONS:
- fully open length: 680 mm
- stroke: 250 mm
- they are installed on the original attachments without making any changes.
