The Bilstein B8 Performance Plus 24-239349 is a rear monotube shock absorber for the 2011-2016 Ford Fiesta SE with the 1.6L four-cylinder. Bilstein B8 Performance Plus dampers are a performance upgrade to OE dampers designed to be paired with aftermarket lowering springs. The manufacturer's material also describes gas-pressure construction and valving set for each application, so this damper suits a driver who wants more control than a stock shock while running lowered suspension.
Why pay more than for a basic replacement? The manufacturer says the single-tube layout dissipates heat better under hard use, which helps keep damping consistent on repeated stops and corners. It also claims a monotube design resists fade and cavitation far longer than twin-tube alternatives. Each unit is fine-tuned during road testing, so the shock is tuned for lowered handling rather than generic use.
Buyers searching for this part often look for a Fiesta SE 1.6L rear shock upgrade, a B8 Performance Plus lowering-spring damper, or a gas monotube rear shock for a 2011-2016 Fiesta. Before ordering, confirm your model year and drivetrain, because published listings disagree on the covered range. Verify fitment against your VIN with the manufacturer, and match the damper to your lowering springs before installation.
