Solving Bump Steer on a Jeep Wrangler JK

What is Bump Steer in a Jeep Wrangler?

From installing larger tires to gaining additional clearance for a day on the trail, there are many reasons Jeep owners add a suspension lift kit to their Wranglers. However, when you install a lift kit, it can affect the steering and handling of your rig; you may experience a condition that is often referred to as “bump steer,” which is the feeling of your Jeep “wandering” all over the road whenever you hit a little bump or dip. Whether you’re travelling on-road or off-road, this condition is disconcerting because you can feel like you have no control over the vehicle.

Why Does Bump Steer Occur?

When you lift your vehicle, it alters the geometry of the suspension and can cause a misalignment of the steering system. The effects can be dramatic on taller lifts. On a stock Jeep, the track bar and drag link are parallel to each other, so when you add a lift kit or make other modifications to the suspension, the angles of these two key parts changes.

How to Resolve Bump Steer with Rancho® Suspension Parts

To get rid of bump steer and ensure that your Jeep JK handles the way you expect it to, it is necessary to restore the angles of the track bar and drag link so they’re close to factory spec. To get these parts parallel to each other, it may be necessary to replace or add some new parts to your vehicle.

Rancho has a solution for getting the track bar and drag link back in spec to help fix or avoid the problem of bump steer in a Jeep Wrangler JK. Installing Rancho’s high clearance steering knuckles used in conjunction with Rancho’s flipped drag link and track bar bracket will get your steering up and out of the way and address bump steer.
