SuperPro SPF1907K Rear Trailing Arm Bushings for Subaru Impreza/Forester/Legacy

Vehicle Fitment

• 1992-2000 Subaru Impreza (GC/GF chassis, FWD & AWD)
• 2000-2011 Subaru Impreza (GD/GG chassis, AWD, incl. WRX)
• 1997-2002 Subaru Forester (SF chassis, AWD)
• 2002-2017 Subaru Forester (SG chassis, AWD, incl. XT)
• 1994-1999 Subaru Legacy / Liberty (BD/BG/BK chassis, FWD & AWD)

Fitment Notes

• Rear lower trailing arm position only
• Some North American retailers list a narrower application (e.g., 2002-2007 WRX, 2004-2008 Forester XT); this reflects the same GD/GG and SG chassis covered above, not a different part
• Confirm your chassis code (GC/GF/GD/GG for Impreza, SF/SG for Forester) before ordering, as trailing arm hardware changed across these generations

Product Description

The rear trailing arm on Subaru's Impreza, Forester, and Legacy/Liberty platforms relies on rubber bushings to control toe and alignment as the suspension moves. Over time these factory bushings wear and soften, letting the trailing arm shift under load and causing inconsistent rear-end tracking, especially during hard cornering or spirited driving. The SuperPro SPF1907K replaces these worn bushings with a two-piece polyurethane kit engineered to hold its shape far longer than OE rubber.

Because the bushing controls the rear-lower mounting point of the trailing arm, tightening this joint has a direct effect on rear toe stability - reducing the arm's tendency to deflect helps the rear axle hold its alignment setting more consistently, which translates to sharper turn-in response and more predictable rear grip. This kit is commonly paired with SuperPro's front trailing arm bushing (SPF1491K) for a complete trailing arm bushing upgrade.

This kit suits Impreza, WRX, Forester (including XT), and Legacy/Liberty owners looking to correct sloppy rear-end feel from aged rubber bushings, whether the vehicle sees daily driving, autocross, or track use. Installation involves removing the trailing arm to press out the old bushings and press in the new ones - most owners handle this with basic hand tools and a press, though shop installation is recommended if you don't have bushing press equipment on hand.
