Suzuki Grand Vitara shock absorbers

Pair of front shock absorbers +1.6" for Suzuli Grand Vitara from 2007.

These shock absorbers are built at the time of order, production takes about 2 weeks.

Kit consists of 2 front shock absorbers extended +4cm; from the top menu you can choose spring plate in original position or raised 40mm. In the first case +4cm springs should be installed, in the second case springs at original height should be installed. 

They have with 60mm reinforced body, 20mm oversized stem, pressurized twin-tube type, serviceable and recalibrated according to your needs.

Entirely Made in Italy, the proposed kit is built with internally lapped steel tubes for mechanical use and fully galvanized to avoid corrosion.

All components are sintered for maximum calibration control and the seals are in graphited Teflon to improve smoothness and silence.

The shock absorbers are calibrated in compression like the originals to favor comfort, but braked more in rebound to reduce vehicle hopping. This calibration is designed to best adapt to the Italian off-road vehicle and is compatible with any type of set-up; in the order phase, however, the desired one can be chosen without a surcharge.

The shock absorber can be re-calibrated and overhauled in all its parts and in the first year after purchase the re-calibration is carried out free of charge according to your needs.

Inside the shock absorber there is a first internal limit switch in extension resistant up to 5000 kg and a second limit switch in polyurethane which slows down the last 10 mm of travel to avoid excessive stress on the frame supports; these limit switches can be used as travel limit for the bridge.

ROTHEN oil with a high viscosity index is used which guarantees maintenance of the calibration up to 200 °C, therefore these shock absorbers are also suitable for heavy use and raids in the desert.

The new 2021 version has the following features:

  • Air Dried pressurization to improve calibration constancy even in extreme conditions;
  • T.I.G. welding for maximum resistance and refined aesthetics;
  • double tube in internally lapped mechanical steel, painted with epoxy powders and phosphated to prevent corrosion, the external tube has a diameter of Ø60 mm and a thickness of 2 mm to resist shocks, if the body is dented the shock absorber will continue to function normally;
  • stem in steel covered in CrVI free hard chrome with tolerance according to EN ISO 286-2
  • 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;
  • high quality SAE5 oil produced by ROTHEN, specially 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 overhaul of the HM4X4 shock absorber is guaranteed at a cost of 40.00 euros each.
AIR DRYED pressurization is an innovative two-stage pressurization technique. It allows you to pressurize the shock absorber with inert gas, after having created a high vacuum, completely extracting air and humidity from inside. 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, Air Dryed pressurization considerably extends the shock absorber's life over time and guarantees constant calibration even after years of use.
