Rear shock absorbers Suzuki SJ 80
Pair of rear shock absorbers +5cm for Suzuki SJ 80.
The shock absorbers are pressurized double-tube, completely Made in Italy. They can be re-calibrated and revised in every part. In the first year after the purchase, the recalibration, upon request, is carried out free of charge in order to adapt the shock absorber to the use you make of the vehicle.
All HM4X4 off-road shock absorbers have the following specifications:
- Air Dried pressurization to improve calibration constancy even in extreme conditions;
- T.I.G. welding for maximum resistance and refined aesthetics;
- double tube in mechanical steel internally lapped, galvanized and phosphated to prevent corrosion, the external tube has a diameter of 50mm and a thickness of 2mm to resist shocks, if the body is dented the shock absorber will continue to function normally;
- 16mm steel rod covered in CrVI free hard chrome with tolerance according to EN ISO 286-2;
- bushings molded with 80 shore thermoplastic polyurethane specific for automotive use, resistant to grease, oil and fuel, highly resistant to deformation and wear;
- sintered internal components for maximum wear-free calibration control;
- sealing band in graphited Teflon to improve the smoothness of the suspension, compared to the 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 weigh on the attachments to the frame and axles;
- ROTHEN shock absorber oil specifically designed for off-road use with a high viscosity index which guarantees regular calibration up to 200 °C, essential for intense use such as races or raids in the desert;
- double adjustment of the rebound and compression settings, both at high and low speeds with translation reed valves preloaded with star springs in compression and coil 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 which in the long run create dirt accumulation and damage the shock absorber, any debris that settles on the rod is cleaned by the double lip of the metal oil seal;
- calibration on test bench at 10 speeds, from 5 to 500 m/s to have the perfect calibration in all conditions.
The HM4X4 shock absorber overhaul is guaranteed at a cost of 40 euros each for the entire life of the shock absorber.
AIR DRIED pressurization is an innovative two-phase pressurization technique, which allows you to pressurize with inert gas, after having created a high vacuum by completely extracting air and humidity inside the shock absorber, in order to limit emulsion phenomena to a minimum. of the oil and the creation of rust, which moisture inside an unpressurized shock absorber inevitably creates. This technique makes the shock absorber more performing and considerably lengthens its life and the constancy of the calibration.
