Frequently Asked Questions
Will the Anti-Rock system fit my 1998 Jeep Wrangler TJ with stock suspension?
Yes the system is designed to work with stock and lifted suspensions. However, for stock-height TJs, you may need to use the shorter arm settings to maintain proper geometry. The frame brackets are universal for all TJ models.
How long does a typical installation take for a first-timer?
to spend 4 to 6 hours for your first installation, including removal of the factory bar. This accounts for dealing with rusted bolts, adjusting the arms, and performing a test drive. Experienced mechanics can complete it in 2-3 hours.
Can I still use my factory rear sway bar with the Anti-Rock?
No, the Anti-Rock completely replaces the factory rear sway bar. You must remove the factory bar, brackets, and end links. The Anti-Rock provides superior performance and adjustability compared to the stock setup.
Do I need to weld anything for the installation?
No welding is required. The Anti-Rock system uses bolt-on frame brackets that attach to existing holes in the TJ frame. This makes it a true bolt-on modification that can be removed and reinstalled on another vehicle if needed.
What is the weight capacity of the Anti-Rock system for a 1998 TJ?
The system is rated for vehicles up to 5,000 lbs gross vehicle weight, which covers a fully loaded TJ with a hardtop, bumpers, winch, and camping gear. It is significantly stronger than the factory sway bar.

“Cars aren’t just machines. They’re freedom, memory, and a little bit of grease under your fingernails.”
I’m Theodore Roosevelt—though my friends just call me “Ted” (and no, I’m not related to the president, though I do share his love for adventure). I grew up in Detroit in the 1970s, back when the city was still the heart of the American auto industry. My first love was a rusted-out 1967 Mustang my father and I rebuilt in our garage when I was fifteen. That project taught me that cars have souls. After spending twenty years as a mechanic and another ten writing for magazines, I started this blog to help everyday drivers and weekend wrenchers feel confident under the hood. Whether you’re restoring a classic or just trying to keep your daily driver alive for one more winter, I’m here to help you get there.
