Rock Krawler 2021+ Jeep Wrangler JT (Diesel) 3in Adventure-X Trail Runner Long Arm System

The Adventure-X Trail Runner Long Arm System for your 2021+ Jeep Wrangler JT Diesel starts with a 3-inch lift, but it's built for much more than just a bit of extra height. This system uses a unique, adjustable-length long arm design that allows you to fine-tune your suspension geometry for optimal performance on and off-road. The long arms themselves are constructed from solid 1.75-inch OD x 0.375-inch wall DOM tubing, giving them serious strength to handle the stresses of trail running and demanding terrain.

Rock Krawler's Adventure-X system incorporates their proprietary triple-rate coil springs, which are designed to provide a comfortable ride on the street while offering excellent articulation and control when you're out exploring. The system also includes a front adjustable track bar and a rear adjustable track bar, ensuring your axles stay centered under the vehicle as you articulate. This is crucial for maintaining predictable handling and preventing tire rub. The long arm mounting brackets are designed to bolt directly to the frame, simplifying installation and ensuring a solid connection. This system is specifically engineered for the JT Diesel model, taking into account its unique weight distribution and driveline characteristics.

When installing this system, you'll want to ensure you have the necessary tools for working with suspension components, including torque wrenches and potentially a spring compressor. It's always a good idea to consult the manufacturer's detailed installation instructions for specific torque values and procedures. This long arm system is a comprehensive upgrade that will significantly change how your JT Diesel handles both daily driving and serious off-road adventures, offering improved ground clearance and enhanced suspension travel.
