Jeep Wrangler

Rubicon Express was founded in 1996. We’ve always been a company of dedicated off-roaders, and our goal has always been to provide Jeep enthusiasts with the highest quality suspension components at the greatest value possible. 15 years later, our focus hasn’t wavered, and we’re proud to be the industry standard in after-market Jeep suspension and drive-train products. Our passion for excellence has been our driving force from day one and we’ve never lost sight of our humble beginnings. We understand and respect the investment our customers make in their vehicles. Our staff members are all Jeepers, and will do their best to answer any questions about our products you may have.

Knowing that a Jeep build is never really “finished”, we’ve engineered all of our Short Arm suspension systems with an upgrade path in mind. This was the basis behind the development of the first Jeep Long Arm suspension system. This allows starting out moderately and then upgrading as desired. Moving forward, we’ll continue to design and manufac- ture unsurpassed suspension systems for all of your Jeep needs, wants and budget. From your daily driver, heading out for the day for a little wheelin’ or a week long trip on the trail, we have the products, knowledge and experience to get you there and back!

Located moments from the Rubicon Trail, Rubicon Express products are real-world tested to ensure the highest qual- ity, function, comfort, and safety. When there’s no turning back, get Rubicon Express... A brand and company you can depend on!
