My Jeep Wrangler YJ '89 went up 2.5 inches First I installed a single Rough Country sway bar to keep the steering under control. I once saw a duplicate stabilizer on Amazon. I thought that installing a dual steering stabilizer would make my bike more stable, but when I bought and installed a dual stabilizer I was shocked, the single stabilizer was stronger. I wasn't impressed with this double stabilizer, waste of money.
