Suspension lift kit with high excursion designed and built in Italy.
The sophisticated components make this lift kit a high-end product capable of making the vehicle very stable and controlled, excellent for amateur or competitive off-road.
This lift kit has been extensively tested in the Italian XTC championship.
Through the drop-down menus at the top right, it is possible to configure the set-up options.
The kit consists of:
- 4 AETERNUS COMPETITION60 shock absorbers, which can be overhauled and re-calibrated (2 front and 2 rear);
- 4 progressive pitch springs +6cm (2 front and 2 rear).
The shock absorber proposed by us, 100% Made in Italy, is built with steel pipes for mechanical uses internally lapped, as well as being phosphated to prevent corrosion, it is entirely subjected to electrolytic galvanizing with Iridescent White finish and subsequent chrome-based passivation. trivalent with surface hardness 80 HV, therefore it is not affected by atmospheric agents and does not strip off.
The bushings are polyurethane, very resistant to deformation and wear, all components are sintered for maximum control over calibration, and the seals are graphitized Teflon to improve smoothness and quietness.
They are calibrated in compression like the originals to promote comfort, but more braked in rebound to reduce vehicle hopping. This calibration is designed to best suit Italian off-road use and is compatible with any type of setup; however, when ordering, the desired one can be chosen at no extra charge.
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 so as to adapt the shock absorber to the use you make of the vehicle.
Inside the shock absorber there is a first internal limit switch in rebound resistant up to 5000kg and a second polyurethane limit switch that slows the last 10mm of travel to prevent excessive stress six supports to the chassis, are usable as a limit of travel for the bridge.
ROTHEN oil with high viscosity index is used, which ensures that the calibration is maintained up to 200°C, so these nissan patrol Gr shock absorbers are also suitable for heavy-duty use and desert raids.
Each Competition60 shock absorber has the following features:
- T.I.G. welds for maximum strength and refined aesthetics;
- double mechanical steel tube lapped internally, painted with epoxy powder and phosphated to prevent corrosion, the outer tube has a diameter of 60mm and a thickness of 3mm to resist impact, in case the body gets dented the shock absorber will continue to function normally;
- rod diam.20mm made of CrVI free hard chrome coated steel with tolerance according to EN ISO 286-2
- polyurethane bushings very resistant to deformation and wear, they are molded with 80 shore thermoplastic polyurethane specifically for automotive use that is impervious to grease, oil and fuel;
- sintered internal components for maximum control over wear-free calibration;
- graphitized Teflon sealing band to improve the smoothness of the suspension;
- compared with cast iron bands, they are much quieter.
- dual polyurethane and steel limit switches to stop rebound travel in a controlled manner and not burden frame and bridge attachments;
- ROTHEN shock absorber oil specially designed for off-road use with high viscosity index that ensures smooth calibration up to 200°C essential for heavy use such as races or desert raids;
- double adjustment of rebound and compression calibrations at both high and low speeds with translation reed valves preloaded with star springs in compression and coil springs in rebound;
- double seal with o-ring and oil seal with metal base, the high quality of the seal makes it possible not to use stem seals which in the long run create dirt accumulation 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 the perfect calibration under all conditions.
HM4X4 shock absorber overhaul is guaranteed at a cost of 40.00 euro each.AIR DRYED pressurization is an innovative two-stage pressurization technique that allows you to pressurize with inert gas after creating a high vacuum by completely extracting air and moisture inside the shock absorber so as to minimize the phenomena of oil emulsion and rust creation that inevitably moisture inside an unpressurized shock absorber creates. In addition to making the shock absorber perform better, Air Dryed pressurization greatly extends the life of the shock absorber and ensures consistency of calibration even after years of use.
The springs are made of high quality steel, are longer than the original, reinforced and with progressive effect, progressive springs unlike traditional ones have variable pitch, that is, the distance between the coils is not constant but varies along its length, the stiffness of a spring with the same material and wire diameter is given precisely by the number of coils and their pitch.
In case a winch or any additional weight above 20kg is installed, you have to choose the winch version through the drop-down menu, which you will find in the upper right corner.
A progressive spring allows you to insert more coils than a traditional spring resulting in a much softer spring, the variable pitch coils during compression harden the spring progressively thus obtaining an extremely soft, comfortable and capable of copying the terrain but very stable on the road.
The main off-road advantages of a progressive spring:
- greater ability to copy terrain;
- greater travel for the same length compared to a traditional spring;
- very stable in lateral passages since it stiffens as it squishes;
- greater absorption of sudden obstacles as it stiffens progressively brakes any obstacle (boulders, roots, etc.) without coming to a buffer.
The main advantages on the road of a progressive spring:
- very stable on fast sections;
- much more comfortable than a traditional spring due to the high number of coils;
- minimizes roll when cornering as it progressively stiffens as it crushes.
The photos are being updated, the new production shock absorbers are supplied galvanized.
