PROGRESS 62.2150 Rear Anti Sway Bar; 24mm (Most wrongly list this as 22mm which is wrong) I ordered this for $170 shipped a year ago, it's still sealed in it's box. Selling for $150 shipped including the ~$20 bolts and nuts that are needed to upgrade to these rear sways for the Prius. I got this for my brother as a birthday present but he preferred a different upgrade. So selling it. Cars this works for: Toyota Prius 2004-2009 Toyota Matrix 2003-2007 Toyota Corolla 2003-2006 Pontiac Vibe 2003-2006 Progress anti-sway bars dramatically improve handling. How? They minimize the traction-robbing body "lean" that rolls part of the outside tires off the pavement. Our Sport-tuned Anti-sway bars replace skinny OEM bars and rubber bushings with larger diameter (stiffer) alloy steel bars and polyurethane bushings. More roll stiffness means less body "lean", and the tires stay flatter on the pavement (larger contact patches). The result is more grip and added driver control! -Less body roll means more traction, faster cornering speeds, and increased driver confidence. -Polyurethane bushings produce crisp response on turn-in. Progress Anti-sway bars are cold-formed in-house using our custom-built precision bending equipment. Both laser-cut and CNC bar ends are MIG welded in place using a precise fixture for an exact fit. Size: 24mm Adjustment Range: None End-links Included: No All sway bars are powdercoated metallic gray. One year limited warranty
