Brand New... Dual Sport Monster High-Performance Suspension System for Early Bronco

We’ve taken our DuckTuff Performance package up another notch and added our Dual Sport 4 Link to it and our Universal Shock Towers. This is the top-tier, most complete 2.5″ 4 link suspension system you can only buy at James Duff, or anywhere else for that matter. What makes it so amazing? We’ve taken all the DNA of our top-performing lift systems such as the 5000t, DuckTuff, and combined them with our brand new Dual Sport 4-Link to give you...well, EVERYTHING! The Dual Sport Monster will make your Early Bronco the best in:

  • Handling
  • Control
  • Performance
  • Driveability
  • On and off-road driving comfort

That's right...Everything!

The Dual Sport is so incredible, it was selected for the Ryan Blaney build which features a 750HP supercharged Coyote and sold as a charity fundraiser for $650,000! In fact, several Early Broncos with 450+ horsepower are finding themselves thirsty for the Dual Sport Monster. Several Bronco Builders have made this their go-to Suspension system. If you have a Coyote Swap or some form of forced induction this is the system we recommend.

With performance comes comfort to push your Bronco harder and faster. We highly recommend upgrading your brake system with our monster disc swap and our hydroboost as well if you want braking power to match your horsepower and possibly even your driving style.
