TeraFlex 1167204

The TeraFlex JK Outback suspension system is designed as a complete suspension system exclusively for expedition style overland travel. This kit was designed from the ground up for a dedicated vehicle capable of supporting sustained self-reliant travel over extreme terrain.

Legendary tracks such as the Canning Stock Route in Australia, or the Silk Road in China prove to be some of the toughest challenges a vehicle will ever face. This approach required TeraFlex to evaluate every component and verify the performance factor for each item. It was found that the majority of our products are by virtue of their original design perfectly suited for dedicated overland applications. Some components were modified to make them more suited for long stretches of washboard roads with no maintenance required. Some of these changes are found in the FlexArm joints - opting to use factory style rubber bushings at both ends of the flexarm. This delivers maximum vibration damping. The allowable flex provided by rubber bushings provides full articulation, utilizing maximum shock travel available. Special consideration and attention was spent on correct spring rate tuning and development.

Dedicated overland travel requires the use of specific spring rates suited to heavy loads and continuous mechanical resonance that react differently than ‘standard’ coil spring rates. This system incorporates custom load-enhanced heavy-duty spring rate coils to meet the performance demands of a fully loaded Jeep and maintain the lift height.

Suspension limiting straps prevent any potential damage to drivetrain or suspension by maximizing down travel safely. Additional details are addressed such as critical gusseting, bracing and other bracketry to beef up areas that are prone to damage and fatigue typically experienced with extended overland trips.

This kit will allow you to run up to a 35” tire (aftermarket wheels with 4.5” backspacing or less are required). Fits all JK Wrangler Unlimited models including Rubicon.
