Jeep Rubicon JK, Modified.

This is the most modified Jeep Rubicon I’ve seen to date that is street legal and it drives like a dream. Many things have been tested beyond its limits and broken. New and stronger parts have since replaced the old and some broken again until this Jeep is in its current state now.

Craig (aka CB) has put a lot of time into this build and it’s not just a rock hopper it’s a full kitted tourer in a short wheel base Jeep Rubicon! Very impressive to say the least…

CB shares a lot of knowledge with building this Jeep and a lot of clever ideas to pack so much into a little big vehicle.

Craig's top 3 trips in the Jeep Rubicon.

1.Tassie West Coast Pieman River North head via Sandy cape American river before it got closed.

2. Great Australian Bite via coast and Cliffs esp Twilight Cove and Bilbunya dunes and Esperance area

3. Madigan line Nth Simson desert into NT.

Unstoppable moment in the Jeep Rubicon:  

Anything sand, high speed rocks follow me if you can and at your peril ??


Most scary situation in the Rubicon: 

Jeep Jamboree 2017;  

The big Step up on the “Commando Track” Coffs harbour Ruby wheel standed (discovered later rear shockers were toast) and just at this point of tipping over backwards (love the shorty) exploded my OE tail shaft uni.

Craig's modification tips:  

Focus first on Tyres, then suspension especially install hydraulic bump stops; they change your life!!!

Things to lookout for with the Jeep JK Rubicon: 

Made in USA so everything ... if it were made in Japan then it  should be made from hardened steel, instead Jeeps are made from mild steel including engines and they don’t care to paint stuff underneath.

Top 3 tips.

1. Keep your build low COG;  its all about up travel.

2.   Replace everything cause it’s going to break anyway.  

3.    Try to  Avoid the “Jeep Rage” that comes from Toyota drivers when you always run circles around them and creates embarrassment moments both on and off road.
