Szekla4x4
IRONMAN 4x4
Reference: NISS040D
A tired spring means a sagging rear end, worse geometry and shock absorbers that wear out faster. This part is made for specific models rather than sold as a universal fit.
This variant is built for an additional load of 50-110 kg — that figure is where the choice of spring starts. Dimensions: wire 17.5 mm, coil diameter 81 mm, free height 380 mm.

Springs are replaced in pairs on an axle — otherwise the car sits unevenly. When you change ride height, check the shock absorbers at the same time: factory shocks on a lifted car work on the wrong part of their travel and wear out quickly.
We do the fitting and pick the whole kit in our workshop in Warsaw. After a lift, a wheel alignment check is recommended.
What does "additional load of 50-110 kg" mean?
It is permanent weight above the factory figure — a steel bumper, a winch, a roof rack, a canopy, a long-range tank. If you carry less than that, pick a softer variant, otherwise the car will ride hard.
How many do I need?
This is one axle set — lifting the whole car needs a set for the other axle as well.
Ironman 4x4 is an Australian brand built for vehicles that really work off-road and carry weight. We fit everything we sell in our own workshop in Warsaw, so if you are not sure which version suits your car, write to us — we will work it out with you.
