We know 4Extreme better

Reliability, performance, comfort and legality are certainly the main aspects that are sought in a 4×4 that will have to face thousands of kilometers both in the toughest offroad conditions and in long transfers on asphalt. In the latter case, it is also essential to be able to travel in compliance with the highway code to avoid unpleasant mishaps. Here is the 4Extreme recipe!

The 4Extreme, born in 2001, has represented a point of reference for travelers since its inception by building and installing fittings, suspension kits, compressed air systems, additional tanks for water and fuel, protection plates, bumpers in stainless steel and aluminum, luggage rack and, the list could go on for much longer, for big African trips and raids on various 4×4 vehicles. To also comply with the need to be able to move freely on the road, in 2008 it was the first company in Italy to have tested a complete set-up at the Ministry of Transport. To learn more about how 4Extreme works, we organized a visit to Pastrengo (VR) at the company headquarters and a test with two Wrangler JKs: an Unlimited 2.8 Rubicon from 2013 and a 2.8 Sport from 2011. On this occasion, we wanted to conduct tests with the Jeeps associated with the heavy-duty trailer always made by 4Extreme. In fact, in pure Australian style, the Veronese company has designed these trailers suitable for off-road vehicles and set up in order to make the adventure travel experience even more pleasant and comfortable.


To meet the need to be able to move freely on the road, in 2008 4Extreme was the first company in Italy to have tested at the Ministry of Transport a complete set up of front and rear heavy-duty bumpers, snorkel, winch and Toughdog + 75mm rise for Nissan Navara D40 and Patrol Y61. On Jeep Wrangler JK also tested the Toughdog + 50mm lift kit. Since 2012, 4Extreme always first in our national territory has tested for the Jeep JK 3 different types of front bumper for heavy use, 2 for the rear, the winch, the snorkel, the increase in the maximum width, the rims as an alternative , the wheel spacers, the conversion into a truck, the Mopar half doors and since 2014 it has also tested the Ohlins suspensions in addition to the Fox shock absorbers. Here is how 4Extreme proceeds for these operations: The testing is carried out at the Vehicle Testing Center in Verona and involves a series of visits to original and transformed vehicles where the compliance of the accessories installed for the transformation is verified to what has been tested on the prototype vehicles initials. Very important thing is that it is possible to test the accessories even on new vehicles without license plates and that the manufacturer’s warranty does not expire!
