What Is Bump Steer — And How to Fix It on Your Lifted Jeep
Ever hit a bump and feel your steering wheel tug in a weird direction? That’s bump steer — and if you’ve lifted your Jeep, you’re probably already familiar. But what causes it, and how do you fix it for good?
Let’s break it down.
🚧 What Is Bump Steer?
Bump steer happens when your suspension compresses or rebounds, and the steering linkage doesn’t stay aligned with your axle movement. This causes the wheels to turn without input from the steering wheel. It feels twitchy, unpredictable, and downright sketchy — especially at higher speeds.
🧰 What Causes It?
-
Incorrect drag link and track bar geometry
-
Lift kits that raise the frame and body but not the steering components
-
Mismatched components or quick installs with poor testing
-
Worn parts and loose joints that exaggerate the movement
🔧 The Fix: Rusty’s Drag Link Flip + HD Steering System
Rusty’s Drag Link Flip relocates the drag link above the knuckle instead of below it, dramatically improving the angles. This realigns the drag link and track bar so they move in the same arc, reducing steering input caused by suspension movement.
Pair it with Rusty’s HD Aluminum Steering System for:
-
1.825" OD solid 7075 aluminum links — strong but lightweight
-
Beefy replaceable ends for easy maintenance
-
Massive control improvement on lifted JL Wranglers and JT Gladiators
🛠 Who Needs This Setup?
If your JL or JT is running 4.5” or more of lift, this upgrade isn’t optional — it’s essential. Whether you're cruising backroads or crawling boulders, your Jeep deserves steering that keeps up with your suspension.
🚙 Final Word from Rusty
We’ve been building, testing, and pushing Jeep steering systems for over 47 years. This isn’t just a quick fix — it’s a tested upgrade built to last.
