Progressive rear springs with variable pitch for Jeep Wrangler JK, 2 doors.
They are built in Italy with high quality 52SiCrNi5 steel in compliance with the UNI EN 10089 standard, by a company certified by TÜV according to the UNI/ISO 9001: 2015 standard.
They are longer than the originals, reinforced with a progressive effect and soft calibration.
These springs raise the vehicle by 7,5cm compared to the original set-up, have a soft calibration optimized to give maximum off-road performance but still perfectly suitable for road use thanks to the characteristics of the variable pitch springs.
The technical data sheet explains how a variable pitch spring works.
