Discovering Your JK Wrangler’s Off-Road Potential with a JKS Jspec 2.5-inch Suspension System and the Right Tires

Hidden Potential

When Jeep introduced the JK Wrangler with a four-door option in 2007, they created a new type of Wrangler owner. While the two-door JK customer stayed closer to the conventional Wrangler customer’s roots, the new JK Wrangler Unlimited was flying off dealer lots, often to serve a more domesticated role in some cases: commuting to work, carpooling to school, picking up groceries, and yes, crawling the mall. In 2012, Jeep introduced a refreshed JK with a modernized interior, an adequate 3.6L Pentastar V-6, and the stellar Mercedes-sourced W5A580 five-speed automatic transmission, further cementing the JK Unlimited’s place in the mainstream.

Like generations of Jeepers before them, the aftermarket bug has bitten JK Unlimited owners too. Today, there are a dizzying number of options, from spacer lifts to Ultra4-inspired coilover suspensions. What’s the JK Unlimited owner to do?

We were invited to Krusher Offroad in Burbank, California, a specialist in late-model Wranglers, to watch a ’13 JK Unlimited Sahara be transformed from mall machine on bald tires to off-road ready. This Jeep’s owner uses his rig for daily tasks typical of a four-door SUV, but also likes to travel off-road. Drivability and reliability were some of the key requirements when it came to suspension selection.

A basic 2.5-inch JKS Jspec suspension system was chosen along with several upgrades to beef up the Jeep’s drivetrain components. It’s worth noting that there’s also a 3.5-inch Jspec suspension available for the JK Unlimited and both 2.5- and 3.5-inch Jspec suspension systems for the two-door JK Wrangler. The JKS Jspec line takes the entire Jeep into consideration with its complete suspension kits that are designed for the driver who wants performance and durability but wants to maintain good handling and ride quality. The takeaway is you don’t have to go big. With a little planning and proper application, a high-quality, moderately sized suspension lift and tire combo can create a very capable JK that is at home on city streets and the dirt. Follow along as we cover some of the highlights of the install.
