Add to cart

Pair of high pressure rear monotube shock absorbers completely Made in Italy, for Jeep Wrangler JL.

From the drop-down menu you can select the desired length and calibration; below is a brief guide to the first choice:
  • Standard with calibration very similar to the original, ideal for the multipurpose use of the vehicle, thanks to the high quality they are excellent even with raised structures or just to improve the driveability of the original structure;
  • Soft for off-road use without additional loads, ideal when using the mostly open vehicle without hardtop and with half doors;
  • Reinforced with more braking calibration to allow maximum stability on the road even with very heavy set-ups or with loads that raise the center of gravity a lot.
  • Customized for trainers who already know the braking values ​​for the set-up to be built.

Each calibration is in any case defined following the order based on real needs.

HM4X4 monotube shock absorbers are characterised by the following features:

  • Ergal head machined from solid;
  • professional grade silicone valve;
  • T.I.G. welding where necessary for maximum resistance and refined aesthetics;
  • internally ground mechanical steel tube, with an external diameter of 52mm and a thickness of 3mm to resist shocks and guarantee the absence of twisting;
  • electrolytic zinc plating with iridescent white finish and subsequent trivalent chromium-based passivation with surface hardness 80 HV;
  • steel rod diam.20mm coated in CrVI free hard chrome with tolerance according to EN ISO 286-2
  • polyurethane bushings highly 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;
  • sealing band in graphited Teflon to improve the smoothness of the suspension;
  • double bump stop in polyurethane and steel to stop the extension stroke in a controlled way and not weigh on the bindings;
  • ROTHEN Fork oil with very high viscosity index (Viscosity DIN 51562 40°C:13) specifically designed for off-road use which guarantees regular calibration up to 200 °C which is essential for intense use such as races or raids in the desert;
  • double adjustment of the rebound and compression calibration (double effect shock absorber), both at high and low speeds with translation reed valves;
  • linear piston with reed valve and adjustable double bypass for maximum comfort at low speeds;
  • high pressure pressurization with inert gas;
  • calibration on test bench at 10 speeds, from 5 to 500 m/s to have the perfect calibration in all conditions.

The HM4X4 shock absorbers can be re-calibrated and revised in each of their components, the revision of the HM4X4 shock absorbers is guaranteed at a cost of 50 euros each for the entire life of the shock absorber.

In the first year after the purchase, the recalibration, upon request, is carried out free of charge.
