Jeep Wrangler JK Bolt-On Steering ConversionPosted in How To: Suspension Brakes on October 1, 2010 0) (
The track bar is one of the most vital parts of your vehicle's suspension and steering system if you aren't running leaf springs. It determines the vehicle's roll center, centers the axle in relation to the vehicle, and controls the side-to-side motion and sweep of the axle as the suspension cycles. In most cases the more length, height, and horizontal positioning that you can set the bar up with the better.?>
But modifications done to the track bar must be mimicked in the steering system.
Failure to do so will result in poor handling and often bumpsteer. Bumpsteer is unwanted movement in the steering wheel that occurs when the suspension cycles. This is usually the result of an incorrect relationship between your track bar and steering linkage. The ideal configuration for the track bar and steering linkage is for both to be of similar or equal lengths and mounted in parallel. Having the lengths the same and the bars parallel will allow the system to cycle in harmony.
One vehicle that has a bit of a tracking issue from the factory is the '07-current Jeep Wrangler JK. From the factory the JK's draglink is made longer than the track bar. In the stock configuration this is hardly noticeable by the driver, but as the vehicle is raised and suspension geometry modified the effects can become more evident.
To address the JK's tracking issues, Evo Manufacturing has introduced a kit called the Correct Track System (CTS). The CTS is a completely bolt-on steering and track bar combo kit designed for JKs running over 3 inches of lift. The CTS works by altering the draglink and track bar configuration to gain a closer parallel and length between the two.
To take a closer look at the kit, we tagged along as our buddy tossed one on his '08 JK, which is equipped with a 5-inch Trail Master lift. For more info you can check out the kit on the web at www.evomfg.com.
