Shop Subaru Legacy floor protection and accessory applications by exact generation and engine. Compare front/second-row coverage and current equipment before selecting shared Outback references. Floor Coverage by Generation Combined cabin packages differ from second-row-only liners. Match exact production, contours, retention points and the supplied pieces. A shared Legacy/Outback title needs the specific year and floor-layout application confirmed. Earlier-generation liners should not be extended to a newer cabin by model naming alone. Lighting and Engine Accessories Fog-light pocket kits require matching bumper geometry, brackets and wiring. Confirm the exact kit application and installation contents. A BRZ-led damper reference needs the correct Legacy engine and supported adapter combination. Pedal controllers separately require exact vehicle and connector coverage.

Shop Subaru Outback exhaust and cabin-protection applications by exact year, engine and floor layout. Match XT/Wilderness exhaust coverage separately from front, second-row and cargo-liner requirements. 2.4T Exhaust and Rear Clearance The displayed AWE 0FG reference targets the specified Outback 2.4T application. Confirm exact year and engine rather than extending it to all Outback powertrains. Its dual BashGuards are designed for rear clearance, while the system includes AWE’s drone-control technology. Review the complete cat-back contents and installation interfaces with existing equipment. Cabin and Cargo Protection Front/second-row sets, second-row-only liners and cargo liners protect different areas. Match exact generation, retention points and load-floor arrangement. Shared Legacy or Forester headings require exact Outback support. Do not assume an earlier cabin or cargo contour fits a later vehicle. Choose Your Part Identify year, engine and trim.

Shop front sway bars, rear sway bars, matched anti-roll bar kits, adjustable sway bars, heavy-duty truck stabilizer bars, off-road Antirock systems, bushings, and service components at Black Ops Auto Works. This collection covers street cars, muscle cars, trucks, SUVs, Jeeps, European performance vehicles, Japanese sport compacts, autocross builds, track cars, and off-road applications. Sway Bars and Anti-Roll Bar Kits A sway bar, also called an anti-roll bar or stabilizer bar, connects the left and right sides of a suspension through a torsion spring. When the suspension moves differently from one side to the other, the bar twists and contributes roll stiffness. This can reduce body roll and change how lateral load transfer is distributed between the front and rear axles.
